Middle Permian fusulinids from Szechuan, China

The Yanghsin limestone of the Mt. Omei region, China, is divisible into three units which we refer, respectively, to the Moscovian(?), Lower Permian, and Upper Permian. In this paper eleven species of fusulinids are described and illustrated from the upper unit of the Yanghsin limestone, and they are referred to the genera Schubertella, Neofusulinella, Ozawainella, Staffella(?), Schwagerina, Eoverbeekina, Verbeekina, Pseudodoliolina, Neoschwagerina, and Sumatrina. The following forms are described as new: Eoverbeekina cheni, Verbeekina grabaui, and V. heimi. Several reports have been published in recent years on the geology of the vicinity of Mt. Omei, on the southwestern edge of the Red Basin, Szechuan Province, China, but very little paleontological work of a systematic nature has been published on the rich faunas found in many of the sedimentary rocks of that part of China. Foster (1923) has discussed rather briefly the stratigraphy and structure of this region, giving a list of fossils collected about 5 miles east of Mt. Omei from strata which he considered Upper Carboniferous or Permian in age. Chao (1929) worked out the general stratigraphic section for the Mt. Omei region and proposed names for the larger lithologic units. Heim (1932) discussed at some length the structure of the Mt. Omei area and summarized the stratigraphy of the region as known up to that
