Not the recent shell. 

 Our recent shells of X. ovoidea collected by the Hartt expe- 

 dition at Bahia, Brazil, show the spire is spirally striate, not 

 costate. In the fossils the spire is strongly tuberculately costate for 

 about five whorls, and the three columellar plications are decidedly 

 heavier. Length 178, width 71 mm. 



We collected a number of specimens and have also some 

 very fine ones sent by Gabb.

Specimens of Vasum engo?iatum Dall from the Chipola 

 River, Florida are very close to Guppy's figure of Sowerby's 

 type of V. haitense and to our Santo Domingo specimens. The 

 most striking differences are ( 1 ) the very squamose surface and 

 ( 2 ) the greater flatness of the later whorls in V. haitense.

 We have a number of specimens resembling V. dominicense 

 Gabb but with only three instead of four plications on the 

 columella. Dr. Dall kindly examined one and notes that it is
