Sipho tuomeyi, PI. 6, fig. 5. 



Syn. Bulbifusus tuomeyi A\d., Bull, i, Geol. Surv. Ala., 1886, p. 23, pi. 

 6, figs. 12a. 



AldricK s original description . — "Shell large, bulbiforni ; whorls 

 seven ; spire moderate ; body whorl very large and globose, 

 flattened above and slightly concave, contra(5led below and 

 fineh^ striated ; aperture oblong-ovate ; outer lip smooth within ; 

 columella strongly excavated, canal wide and curved. 



"'Locality. — Bell's landing, Alabama. 



' 'This species may onl}^ be a strongl}' marked variety of B. 

 inauratus Con. , * * * but the younger specimen * * * from 

 Gregg's landing differs from Conrad's species in having finel}^ 

 revolving lines over its whole surface, whorls convex, closely 

 appressed at the suture, while the other has the whorls concave, 

 the lines obsolete on the central part of the body whorl, is 

 shouldered at the suture, which is in a groove, and generalh' has 

 the first four whorls of the spire with a row of revolving nodes 

 above the suture." 



This is a very thin delicate form, found at Gregg's landing. 

 Aldrich's type specimen bearing the original label with statement 

 that it is the type and has been figured, says plainly "Gregg's 

 landing. ' ' 



This thin shell with very rounded or bulging spiral whorls may 

 possibly be related to Mazzalina but it seems to us closer still 

 to the living Sipho ventricosus off the coast of Newfoundland.
