 species. 



1449. TURRITELLA SPIRATA. 



T. testa turritd, albid^, apice obtuso, anfractibus 

 transverse costellatis, longitudinaliter fusco-fasci- 

 tis, supern6 ad suturam depressione complanat^

Obs. From the Island St. Thomas. The point 

 has probably been worn off, it has nevertheless been 

 closed by the animal, so that it maybe termed decol- 

 lated. Two circumstances are remarkable in this 

 shell, the broad flat depression of the upper part of 

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

 Aware that it is generically distinguished by this lat- 

 ter circumstance from Turritella, we would not have 

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

 venient place for it. Two other specimens are amon^ 

 the shells which I bought from G. Humphrey. 



1503. PLEUROTOMA CRYPTORRHAPHE. 



P. testa turritd, transverse striata umbilicatd; an- 

 fractibus infra medium unicarinatis, linea superne 

 infra suturam profunde impress^ ; cauda brevi ; 

 long. 2^ unc. lat. f unc. 



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.
