176 THE VOYAGE OF H.M.S. CHALLENGER. 



which lies a furrow. Colour white. Spire low and stumpy, and subscalar. Apex broken. 

 Whorls : there are 4f remaining ; they are short, broad, and convex ; the last is a little 

 tumid, with a short rounded base. Mouth direct, small, round. Outer lip regularly 

 curved ; the canal, with reverted lip, is very oblique, lies in front of the pillar point, and 

 comes short of the prominence of the basal lip. Inner lip is flat across the body, and 

 advances there very little ; at the base of the pillar it is flatly concave ; the pillar is 

 excessively short, and its extreme point does not project beyond the canal edge and the 

 bottom of the canal, these two being, in consequence of the obliquity of the canal, at the 

 same level. H. 0-54 in. B. 0-36. Penultimate whorl 0'14. Mouth, height 0-29, 

 breadth 0-17. 



I know no Nassa which approaches this in the shortness of its pillar and the shallowness and 

 obliquity of its canal. In general form and sculpture it recalls Nassa ventricosa, Bellardi, or some 

 of the other allied fossil forms from the Upper Miocene of Piedmont. Nassa perpinguis, Hinds, with 

 which Bellardi compares that species, is very much longer, with stronger and more oblique sculpture, 

 than the Challenger form. Our species is unfortunately in the worst possible condition.
