UROSALPINX, Stimpson. 

 U. Floridana, Conrad. — PI. 12, fig. 4. 



Bescriptioyi. — Fusiform, longitudinal ribs distant, prominent, 

 thick, rounded ; spire prominent, scalariform ; whorls 6, penulti- 

 mate whorl with 3 prominent revolving lines ; last volution 

 profoundly ribbed and having 10 conspicuous prominent revolving 

 lines ; caudal ridge prominent, curved ; beak recurved, longitu- 

 dinal prominent wrinkled lines are conspicuous over the whole 

 surface ; aperture and columella purple ; labrum with 7 lines 

 within. 



Locality. — Tampa Bay, Florida. 



This shell somewhat resembles Murex craticulatus. 



It is rough, cinereous in color, and the lower part from labrum 

 summit to extremity of siphonal canal is three-tenths of an inch 

 longer than from the summit of labrum to apex.

Mr. R. E. C. Stearns has presented to the Academy a fine adult 

 specimen from Florida and a young shell, which, compared with a 

 specimen of carica of about the same stage of development, pre- 

 sents the following differences : thicker than carica, the spines 

 larger in front, but suddenly becoming very thick, distant and pro- 

 foundly elevated on the back, whilst in the carica they continue of 

 a comparatively very small size. The color of elieeatu is bright 

 reddish brown, having a tinge of purple, with a broad white colu- 

 mella. The columella of carica is striated and has dark purple 

 lines, whilst the general color of the markings is purple black. 

 The lines of distinction between eliceans, carica, Kieneri, perver- 

 sum, coarctatum and candelabrum are strongly defined. If jB. 

 carica and B. perversitm are one species, how is it thdii p)erver sum 

 should be abundant in Florida and unknown on the coasts of the 

 Middle and Eastern States, where carica abounds ? The perver- 

 sum attains a far larger size than carica; indeed I have never 

 seen an adult specimen of the latter among Florida shells, nor 

 did I see a specimen of any kind during the two months I was 

 collecting on the southern coast of Florida.
