Tryon's figure and description are both unsatisfactory. The 

 species attains greater size than he indicates ; a decollated shell 

 before me, of which 8|- whorls remain, is 237 mm. long and 1 00 mm. 

 broad, thus exceeding the original dimensions by about two 

 inches. In general shape narrow fusiform ; whorls of the spire 

 angled in the middle, the angle cut into 12-14 sharp projecting 

 nodules. On last whorl the angle occurs above the flattened 

 periphery, base excavated. Ground colour cream on which 

 chocolate appears everywhere in dots or lines. On the base 

 these gather into obscure bands ; between the peripheral nodules 

 and on the tip of the canal the chocolate appears in darker 

 patches. Entire surface covered with flat topped spiral lublets 

 parted by wide and shallow furrows. Outer lip denticulate at 

 the edge by external sculpture, lirate within. Inner lip a mere 

 smear of callus. Canal broad, open, varying from nearly straight 

 to flexed in an S curve. 



The series at my disposal is imperfect, but so far as it goes it 

 leads me to dissent from the following opinion so emphatically 

 expressed by Prof. Tate* and endorsed by Pritchard tt Gatlift'if
