These are small shells of oval outline with an almost uniform convexity, 

 beaks well toward the front and very low umbonal ridge. They are about 

 one third longer than high and are especially noteworthy for the strong 

 development of the umbonal teeth, which are slightly curved ridges, the 

 median one much the strongest, bounded by deep sockets and a more 

 subdued tooth above and below. 



There are no Cypricardellas of this type in the New York faunas where 

 they are chiefly characterized by sharp concentric lines and strong umbonal 

 ridge. Such shells as these are however very closely similar to C . b i c o s- 

 tata Krantz and C. elongata Beushausen, 1 especially to the former. 



Locality. Moosehead lake, a little north of Soccatean point, Me.

We have already noted the probable presence of this species in the 

 Chapman Plantation fauna. The specimens before us though not abundant 

 in our collections seem to present no distinction from the lower Coblentzian 

 shell referred to, and we are disposed to assign them to that species without 

 further question. 



Localities. Moosehead lake, a little north of Soccatean point ; also on 

 Presque Isle stream, Chapman Plantation, Me.

Shells elongate with anterior beaks ; narrow in front, widening behind 

 and with a very high and bluntly angular umbonal ridge behind which is 

 an abrupt posterior slope and in front a well marked sinuosity or radial 

 depression. The posterior extremity of the shell is quite narrow and 

 subacute.
