The only specimeu.s referred to this species are those from the Uinta Moun- 

 tains, which were so identified b^- White. Although the}' are mere casts, so that 

 I have been able to see none of the surface ornamentation, from their size and 

 configuration it seems not improbable that White'.s identification may be correct. 



Some of the exfoliated specimens which have been placed with EuplieinvM nodo- 

 carinaims^ or even with Belleroplion crassus maj- , however, belong here. I am dis- 

 posed to give this type, for which White proposed only a varietal name, full specific 

 rank. 



Locality and horizon. — Uinta Mountain region, near the south fork of the Ver- 

 milion and near the east base of Diamond Peak (station 2189); Bellex-ophon lime- 

 stone at the ver}' top of the Carboniferous. 



CEPHALOPODA. 



DOMATOCERAS Hyatt, 1891. 



DOMATOCERAS Sp. 



It is probable that the .same species occurs at both the localities cited below, 

 though the condition of my material does not permit me to speak with confidence. 

 The form is not determinable from the specimens in the collections. 



Locality and horizon. — Leadville district (stations 2275 and 2276); upper portion 

 of the Weber formation.
