cies has the right side of the base somewhat more obliquely trun- 

 cated ; so that there is much less of inequality between the two 

 sides than in the ' Challenger ' species, which is also slimmer, has 

 the sculpture both of ribs and spirals very much finer, the apex 

 much smaller and higher, the suture less deep, and the nick of 

 the canal in front very much more distinct.

This species extremely resembles P. septangularis, Mont., in 

 general appearance and in sculpture, both as regards ribs and the 

 fine spiral striae. In form it is smaller, narrower, and much more 

 cylindrical, the body- whorl is similarly tumid ; but it and the 

 mouth still more are shorter ; the penultimate whorl is very much 

 smaller and especially is narrower ; while the upper whorls are 

 broader, and the apex very much broader and blunter. The spe- 

 cimen is in too bad condition for detailed description.

Shell. — Small, rather narrow, biconical, continuously ribbed, 

 microscopically spirally striated, with a very blunt tip, a rather 

 fine but expressed labral varix, and a very slight shallow sinus 

 which does not cut through the lip. Sculpture. Longitudinals — 

 there are eight narrow, rounded, prominent, direct, very slightly 

 oblique ribs, which run continuously from apex to point of base ; 

 there are also very faint scratches in the lines of growth. Spirals 

 - — the whole surface is very delicately fretted with microscopic, 

 regular, sharpish spiral stria?. Colour warm yellowish-white, with 

 a ruddy band below the suture. Spire regularly conical. Apex 

 consists of rounded, globose, smooth whorls, of which the tip is 

 broken. Whorls 6 remaining, of regular but rather rapid increase, 

 rather high and narrow, just perceptibly convex; the last is 

 small, very little tumid, with a short, conical, lop-sided base, ending 

 in a very short, flattish snout, crossed by the longitudiual ribs. 

 Suture linear, scarcely impressed. Mouth very small and narrow, 

 with almost parallel sides, narrowed above into a small narrow 

 sinus, which cuts only halfway through the thick outer lip ; the
