couchologist and naturalist, M. Hippoly te Crosse, of Paris, wliose lat)ors 

 have ameliorated every department of malacology. 



The exact locality of this shell is not known, but it is probable that 

 Colonel Jewett collected it with other minute shells on one of the Keys. 

 It w^as presented by him to Dr. R. E. C. Stearns, and acquired by theU. 

 S. National Museum with the Stearns collection. 



Genus BLAUNERI^ Shuttlewortli. 

 Blauneria Sbuttlewortli, Berner Mitth. Diagn. Neue. Moll, p. 148, 1854. 



Foot simple, i)ointed behind, transversely sulcated (?) ; tentacles short, 

 cylindrical, eyes behind and above their bases ; shell ovate elongate, 

 sinistral, thin, aperture long, narrow ; peristome slightly thickened, 

 outer lip slightly incurved in the middle, continuous with the twisted 

 subtruucate columella ; one strong, parietal fold, with a thin callus on 

 the body whorl ; last whorl the largest, suture indistinct, appressed. 

 Type B. heterocUta Montague. 



The sulcation of the foot in the typical species does not seem to have 

 been recorded, though it is known to exist in B. gracilis Pease, accord-, 

 ing to Dr. Paul Fischer.

Habitat. — Cuba, Jamaica, Porto Rico, Arango; Tampa Bay, Florida, 

 Jewett and Stearns ; in damj) moss of dried-up brackish swamp near 

 Marco, Fla., Hemphill ; introduced into England, Laskey. 



I understand from Mr. Tryon that he suspects the Cuban shell to be 

 different from the British and Floridian specimens, but all that I have 

 seen seem to belong to one species, and the various figures seem to 

 agree very well together.
