prolons^ed downward obliquely in the form of small riblets, which, 

 on the subsntural band, become strongly excurved, thinner and more 

 shai-ply raised ; these whorls are also sculptured by a few, distinct, 

 raised, spiral lines, both below the shoulder and on the lower part of 

 the broad subsutural band. The nucleus appears to have been regu- 

 larly tapered and finely cancellated, but is eroded in both specimens. 

 The aperture is rather large, elongated, fusiform, with an acute pos- 

 terior angle and a short, straight canal a little constricted at the 

 base ; the columella is nearly straight, with its edge only slightly 

 sinuous. 



The color of the shell within is dull flesh-color, with a patch of 

 brown on the columella; externally the color is brownish salmon or 

 pale chestnut-brown. 



Length of the largest specimen, 22™"^; greatest breadth, 11'"™ ; 

 length of body-whorl in front, 17™"^ ; length of aperture, 14"™; great- 

 est breadth, 4™™. 



The living specimen (No. 44,652), described above, was taken at 

 station 2,225, in 2,512 fathoms, N. lat. 36°, 05', 30"; W. long. 69°, 

 51', 45". A smaller, dead specimen (No. 44,651), occurred at sta- 

 tion 2,224, in 2,574 fathoms. 



This species bears considei-able resemblance to P. Mnertoni V. in 

 form and general appearance, but differs very decidedly in color and 

 the details of its sculpture.

Plate XLIV, figure 5. 



Shell of moderate size, rather thick and solid, elongate-ovate or 

 subfusiforra, with a rather long, regularly tapered spire, consisting 

 of about six whorls below the nucleus, which is small and consists of 

 two or more whorls, eroded in our specimens. The whorls of the 

 spire ai*e a little convex and slightly angulated or shouldered just 

 above the middle, and have a rather broad, slightly concave subsu- 

 tural band ; the last whorl is more evenly convex and the shoulder is 

 rounded and rather indistinct. 



The surface is covered with numerous rather fine, flexuous riblets, 

 parallel with the lines of growth ; these curve forward on the middle 

 of the whorl below the shoulder, but are strongly excurved in cross- 

 ing the subsutural band, and become thin and more prominent just 

 below the suture, which is distinctly impressed. The surface is also 

 covered with very numerous thin, revolving cinguli, which are sepa-
