This is, as the author himself suspects, perhaps an elongated 

 variety of Marinula cequalis.

4. PEDIPES, Adanson. 



Shell imperforate, ovate- or globose-conic, solid, striated 

 spirally ; whorls few, the last inflated, much larger than the 

 spire; aperture rather semicircular or ellipsoidal, modified by 

 three plaits, of which the parietal one is very large, lamelli- 

 form, entering spirally ; the two others dentiform, placed on the 

 margin of the flattened columellar lip ; peristome sharp, callous, 

 or toothed within. 



Animal like that of Melampus, except the foot, which is 

 divided into two parts, separated by a transverse groove. The 

 anterior part is broader than long, transverse, rounded ante- 

 riorly; the posterior part longer than broad, truncated ante- 

 riorly, somewhat attenuated and obtuse posteriorly, short, semi- 

 ovate.
