TAINOCERAS Hyatt, 1883. 

 Tainoceeas sp. 



A single specimen, crushed in shale and macerated, has been found. It is 

 evidently related to T. occidentalis Swallow, but it is too poorly preserved to admit 

 of identification. 



Locality and Iwrizon.. — San Juan region (station 2201); upper portion of the 

 Hermosa formation.

Sandstone of the Missouri; near Engineer Cantonment. 



This species has been identified at three localities, but at each only one specimen 

 was found. They are veiy imperfect, being more or les.s crushed and exfoliated. 

 Differences have been noted which, were the material better and more abundant, 

 might have justified me in discriminating two groups where now I recognize but one. 

 The form from Ouray, especially, shows characters which, if constant, should separate 

 it from the two other specimens, which are mutually more alike. Herrick " casts doubt 

 upon Meek's identification, in his Nebraska report, of Shumard's species. The 

 Colorado forms are of the type figured by Meek, but show departures which might, 

 with adequate material, prove varietal, or even specific.
