 310-2199 fins. 



Has somewhat the size and appearance of E. glabra, but is more 

 cylindrical, and differs particularly in the apex, which is blunt in the 

 present species, thus connecting it with E. stenostoma. It is not the 

 E. oblusa of De Folin (' Les Fonds de la Mer,' p. 211, pi. xxxviii. 

 f. 11), which is apparently E. stalioi.

Several names of other species both of the present genus and of 

 Odostomia have been proposed by the Marquis de Monterosato in 

 his catalogues ; but as they were not sufficiently, if at all, described, nor 

 any of them figured, I cannot identify them, and I fear the names 

 must be treated as manuscript.
