82 THE NAUTILUS. 



A well-marked feature of the hinge is, as it seems, the relative 

 position of the teeth, the distance between the cardinals and posterior 

 lateral cusps being twice as long as that between the cardinals and 

 anterior laterals. In other species, e. g., Pis. compression, variabile, 

 noveboracense, that difference is much less marked, and in P. vir- 

 ginicum the cardinals are about equidistant from the laterals.

This shell, received by MM. Sowerby and Fulton as E. clansottL- 

 phalos (?), Dev. & Hupe, is quite unlike the latter, but is related to 

 a species of smaller size that one of these gentlemen sent me some 

 years ago as E. Farrisi Higg., or rather E. Higginsi Pfr., the former 

 name being preoccupied. However it does not seem to correspond 

 with the original diagnosis. The present species is larger, its sur- 

 face is rough but of a plain brown color, ornamented with a brown 

 band and the umbilicus is nearly closed. 



Epiphragmophora Turtoni Anc. 



This I have described in the journal as probably Bolivian, but 

 subsequently my friend Mr. Gude has described from Paraguay an 

 E. ZW/ttm, which appears to be very close to it and of which I have 

 seen the type in his collection. Both are probably from the same
