The systematic position of the genus Lyubimovina

The new subfamily Galliaecytherideinae is established in Cytherideinae Sars, 1925 for Galliaecytheridea, Lyubimovina, Palaeocytheridella, Asciocythere, Rubracea and Procytheridea. Lyubimivina is removed as a subgenus Palaeocytheridella and given generic status. Morphologic, phylogenetic and geographic justifications for the above actions are discussed. — I. G. Sohn.     

Bivalve mollusks of the Far Eastern Seas of the U.S.S.R. (Order Dysodonta)

This short section of Skarlato's monograph, Bivalve Mollusks of the Far Eastern Seas of the U. S. S. R. (Order Dysodonta), discusses the genus Arvella Bartsch, 1940 ms. The genus includes the species formerly assigned to Crenella. Diagnostic features of the species included in genus Arvella Bartsch are given. Vilasina Bartsch, 1940 ms is discussed, also The author states that the hinges of Vilasina clearly assign the species to the genus Crenella. The form and position of the umbo relate the species closely to the genus Arvella, though. The almost entirely smooth laminated surface distinguishes Vilasina from both genera, as does the finely serrated ventral edge of the shell. The last section discusses the genus Modiolus Lamarck, 1799. — A. W. Bellais.     

NEW SILURIAN GENUS,URALOGRAPTUS

A new graptolite genus is described from lower Wenlockian rocks on the Molyud-Vozh river in the northwest Urals. Uralograptus closely resembles Cyrtograptus but lacks the spiral coiling of the main part of the rhabdosome. U. insuetus, the type species, was collected from the zone of Oktavites spiralis (Geinitz). --B.S. Norford.

New species of Miocene foraminifers from eastern Ciscarpathia

Putrya describes the new species Streblus galicianus, S. mjatliukae, S. pseudobeccarii, and S. granulosus from upper Tortonian (Miocene) deposits in Ciscarpathia.—M. A. Buzas     

New gymnosperms from the Lower Cretaceous of the Primor'ye

A new species of Caytonia, C. orientale, and a new genus and species Chankanella vachrameevi are described from Neocomian-Aptian coal bearing strata in the Primor'ye Territory, Suifun basin. The new species of Caytonia is differentiated from C. sewardii Thomas and C. canadensis (Berry) Bell on the basis of size and slight morphological variances. Only one specimen of a megasporophyll was available for study. Leaves found in the same stratum and attributed to the new species differ from other species of Sagenopteris chiefly in the greater length of the petioles of the leaflets. Chankanella vachrameevi is described as a Sagenopteris-like leaf. It differs from Sagenopteris in having a larger number of leaflets and in lacking anastomoses of veins in the leaflets. It is compared with Lesleva Lesquereux. Its leaflets are compared with Thinnfeldia pinnae, and the leaves of Tersiella Radczenko, Linquifolium and Protophyllocladus. — F. M. Hueber.     

VERTICAL MIGRATION OF PETROLEUM INTO CARBONIFEROUS AND PERMIAN DEPOSITS OF THE VOLGA-URAL PROVINCE

Three new species and two new genera of scleractinian corals are described from the upper Oxfordian (Jurassic) limestones of Azerbaijan. Cyathopora parva, Thecosmilia vurguni, and Thecosmilia zagaliensis are described as new. The genus Brevimaeandra (Type species: B. alizadei nov. sp.) is compared with Mycetophyllopsis and Maeandrastraea, and is placed in the Family Montlivaltiidae. Grandifavia (Type species: G. bendukidzeae, nov. sp.) is placed in the Family Faviidae and is compared with Favia and Nefocoenia. No other constituents of the fauna are listed nor are references to such lists given. A brief introduction states that the limestones of middle Oxfordian age are probably reworked reef deposits, and that the coral and sponge reefs were deposited in waters probably not over 90 m deep. No stratigraphic sections are given. — D. F. Squires.     

Beresellids from the Carboniferous of the Russian Platform

The classification of the tribe Bereselleae of the family Dasycladaceae is discussed in some detail. The genera Beresella, Samarella and Dvinella are placed in the tribe with Trinodella, being treated as a subgenus of Dvinella. A number of new species are described: four in Beresella, six in Dvinella subgenus Dvinella and two in Dvinella subgenus Trinodella. The stratigraphic occurrence of the tribe in the Carboniferous at a number of localities on the Russian Platform is represented and a strong generic-facies association is pointed out. A pattern of variation in morphological form with sediment type is also discussed. — W. Adey.     

A Fammenian rhynconellid assemblage common to North America and the Urals

Rozman, describing in 1960 the Famennian deposits of Mugodzhar, mentioned a new genus Pseudonudirostra to which were assigned Pseudonudirostra uralica (Nalivkin, 1947), P. posturalica sp. nov. and P. planoovalis (Nalivkin, 1937). Sartenaer in 1961 distinguished the genus Trifidorostellum with the type species Leiorhynchus dunbarense Haynes, 1916. A year later Rozman (1962) described the new genus Pseudoleiorhynchus (= Pseudonudirostra), with the type species Leiorhynchus uralicus Nalivkin. Sartenaer in 1963 visited Russia and both authors concluded that Pseudoleiorhynchus was a junior synonum of Trifidorostellum. The early Famennian T. dunbarense of America and the late Famennian T. uralicum of Russia form a single group of species of stratigraphic value for intercontinental correlation of Famennian deposits.--A.W. Norris.     

SOME EARLY TRIASSIC AMMONOIDS FROM THE NORTHERN CAUCASUS

Ammonoids of early Upper Scythian age are described from three localities in the Northern Caucasus. No data on relative stratigraphic position is given, but some forms are common to the different exposures and the author concludes that all the ammonoids are Upper Scythian (Olenekian). Affinites with Pacific faunas are stressed and the faunules are correlated with the Owenites zone of North America. Two new genera (Parinyoites and Subowenites) and three new species (Dieneroceras caucasicum, Parinyoites ,mastykensis, Subovvenites slavini)are proposed. Flemingites pulcher Waagen, Wyomingites aplanatus (White), Parussuria compressa (Hyatt and Smith), and Owenites koeneni (Hyatt and Smith) are described and figured. Parinyoites differs from Metinyoites in having rounded saddles and it lacks the keel and costation of Inyoites. Subowenites has reticulate ornamentation, unlike Owenites, Parowenites, and Pseudowenites; it also lacks the adventive notches in the median saddle of Pseudowenites. --E. T. Tozer.     

The genus Nathorstia (ferns)

Nathorstia is a genus of Cretaceouslern with a broad distribution in the Northern Hemisphere. Previous authors have disagreed on the systematic position of Nathorstia, but investigation of the epidermis and sori of material from the lower Cretaceous of Primor'ye, Suyfun basin, has helped to clarify the problem. The genus was originally described by Heer, who assigned it to the family Marattiaceae, because of erroneous interpretation of the son. However, the true affinity is apparently with the Matoniaceae, particularly with the genus Phlebopteris Brongniart. A diagnosis of Nathorstia is presented, and N. pectinata (Goeppert) Krasilov, n. comb. (formerly Reussia pectinata Goeppert) is designated the type species. — S. H. Mamay.     

Microstructure of septal system in some Silurian tetracorals

The microstructure of the septa is examined for some genera of the Lykophyllidae. Two distinct types of microstructure can be recognized, enveloping lamellar microstructure in which the fibers parallel each other and the median part of the septum, and pinnate-fibrous microstructure in which the fibers diverge at an acute angle from the median part of the septum and are commonly arranged in bundles. The Lykophyllid corals have thick septa in the young stages but the thickening reduces with growth. Three patterns of such reduction of septal thickening can be recognized: 1) reduction proceeding from the counter quadrant to the cardinal quadrant; 2) reduction proceeding from the periphery towards the axis; 3) reduction proceeding from the cardinal quadrant towards the counter quadrant. The Lykophyllidae are divided into two subfamilies, the Lykophyllinae with enveloping lamellar microstructure and the Semaiophyllinae with pinnate-fibrous microstructure. The pattern of reduction of septal thickening is different for the two subfamilies. A new genus, Rukhinia (type species R. cuneata n. sp., Upper Llandoverian of the western margin of the Siberian Platform) is proposed and is closely related to Semaiophyllum Vollbrecht.—B.S. Norford     

Phylogeny of Gaudryina-Gaudryinella

Kurgalimova discusses the displacement of the aperture and the modification of its shape in the genera Gaudryina, Belorussiella, and Paragaudryina. The species G. navarroana Cushman, B. intermedia sp. nov., and P. pseudonavarroana (Balakh.) occur in fairly distinct stratigraphic position in lower to middle Eocene deposits of the southeastern part of the Turgay depression, South Emba and Bukhara Province.—M.A. Buzas
