slope on the anterior side ; lower part of the cone obscurely plicated, 

 aperture nearly round. 



This singular expression of Platyceras, noteworthy for its broad, blunt 

 apex, is quite unusual in American faunas, but such a shell has been noticed 

 by OEhlert in the Lower Devonic of Angers and figured in the Bulletin 

 de la Socihtd Geologitjuc dc France, 1890, volume 17, plate 19, figure 4.

There seems no doubt of identity in this case. The species is a Platy- 

 ceras with a Diaphorostomalike spire from which the body whorl expands 

 rapidly and carries a deep revolving sulcus on the lower side. 



Locality. Edmunds Hill, and in the Spiriferensandstein of the Hartz 

 qountains at the Kahleberg.

A shell of relatively rare occurrence with very faint sinuous ridges on 

 the internal cast. It suggests the species referred to from the Spiriferen- 

 sandstein of the Hartz mountains.

The pterineoids of this fauna are chiefly true Pterineas and none show 

 the degenerative condition of the hinge structure which accompanies ami 

 characterizes the generally later genera Actinopteria and Liopteria. This 

 species is radially and coarsely ribbed, quite convex and oblique along the 

 crescence line, the anterior wing strongly developed on the abrupt anterior 

 slope and' the hinge teeth both beneath the beak and behind it very pro- 

 nounced. In all respects it is very like the species cited so far as the former
