MOLLUSKS. 43 



mark on fuci, show such great variations in form of aperture, acuteness 

 of the spire, and general proportions, that I am unwilling to describe 

 them as new, though the diagnosis of Mr. Smith does not seem in all 

 respects applicable to them. None of them exceed four and a half 

 whorls in extent, the aperture being nearly one-half as long as the 

 shell. A faint umbilical chink is perceptible in a greatly enlarged 

 camera-drawing. The largest specimen is 4.5™°i. in length and 2.3'"™. 

 in width. If, on comparison, the specimens should be found to differ 

 from the form described by Mr. Smith, they may be called Eatoniella 

 inflata. 



The operculum of this species, besides being subspiral instead of con- 

 centric, differs from that of Rissoella Gray {=Jeffreysia, Alder) in having 

 the process extended at a much more obtuse angle, but on the same 

 side of the operculum.
