The species belongs to the group of the Cystoids. Among the brachiopods, S t r o p h e o d o n t a v a r i s - t r i a t a [fig. 35] is the most abundant and characteristic of the lower beds. It is fre- quently larger than in the Manlius. Other characteristic brachiopods are : C a m a r o - Fig. 34 Lepadocrinus gebhardi t 0 e c h 1 a s e m i p 1 i c a t a [fig. 36], a small species, smooth in the upper portions and with a few small plications near the base; very abundant in some of the layers and represented by a variety [see fig. 27 ah] in the transition beds at the top of the Manlius; U n c i n u 1 u s m u t a b i 1 i s [fig. 37], a robust, rounded form with numerous rather faint and rounded plications, and pro- nounced anterior emargination. Fig. 35Stropheodontavarlstriata often occurs m considerable abundance; Atrypa reticularis [fig. 38], generally robust and easily recognized by the unequal convexity of the valves and the reticulated surface markings, and S i e b e r e 11 a galeata [fig. 39], easily recognized by its form, the strong [overarching beak of the pedicle valve and the strong rounded.
