周口店多足类化石

1932—1937年间在周口店中国猿人产地及其他地点采得八十馀件节足动物化石,多破碎,完整者极少。颜色不一,由乳白而棕黄,兼有呈半透明玻璃状者。经初步观察,应属节足动物门,多足纲,倍脚目,马陆科,计一属两种: 一、山马陆(Julus of.terrestris)此种在第一,三,十五地点及山顶洞均有发现。此与现生的山马陆无甚差异,仅肛板及由二肛板所成之肛门沟稍大。二、裴氏小马陆(Julus peii Chia & Liu(sp.nov.)此种於第一,四,十五地点及山顶洞均有发现。由身体及头部形态,身体环节数目(三十个以上),知其与山马陆同属。但其决非幼小山马陆,因其体节数目多於长成之山马陆。但与现生於日本的一种 Nipponoiulus truncatus 近似,惟後者体节数较少,尾端钝圆。关於马陆属化石,据现在所知最早发现於始新统地层中,直到现在仍有生存,变异极小。以上所述二种若非与其他脊椎动物化石共生於周口店地点,则其年代颇难鉴定,因其有以後爬入岩隙死後石化之可能,不过上述之标本不但有共生脊椎动物为证,且有的已埋藏於固结的砾岩中,其属於更新统时期可无疑义。

STRATIGRAPHY OF SOUTHEASTERN HUPEI

The geology, of the southeastern part or Hupei has been studied by Mr. Seijirro Noda of the Japanese Geographical Society in 1912. A geological map in the scale of 1:400,000 was prepared by him, covering the districts Ta Yeh, Yang Sing, O Cheng and Wu Chang. Mr. Noda classified the sedimentary rocks into the following series:
