82 THE NAUTILUS. 



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

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

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

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

 noveboi-acense, tliat difference is mucli less marked, and in P. vir- 

 giiiiciim tlie cardinals are about equidistant from the laterals.

This shell, received by SIM. Sowerby and Fulton as E. clansom- 

 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. Dormer i,\\\\\Q\\ appears to be very close to it and of which I have 

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