Ohs. From tlie Island St. Thomas. The point 

 has probably been worn ott", it has nevertheless been 

 «closed by the animal, so that it may be termed decol- 

 lated. Two circumstances are remarkable in this 

 shell, the broad Hat depression of the upper part of 

 the volutions, and the straight edge of the outer lip. 

 AM'are that it is generically distinguished by this lat- 

 ter circumstance from Turritclla, we would not have 

 added it to this genus had there beeii any more con- 

 venient place for it. Two other specimens are among 

 the shells which I bought from G. Humphrey. 



1503. PLEUROTOMA CRYPTORRHAPHE. 



P. testa turrit.1, transverse striata umbilicatA; an- 

 fractibus infra medium unicarinatis, line.1 superne

Obs. The keel appears to be placed in the mid- 

 dle of each volution, because the impressed line be- 

 neath the suture is much more conspicuous than the 

 suture itself.
