HEMIPLEUROTOMA TASMANICA, N.S. (PL. 

 XIV.. FIG. i6.) 



391 



Shell solid, rugged, elongate fusiform, dull bluish 

 white; whorls nine, including the protoconch of three 

 Avhorls, of which the first is smooth and round, the others 

 obscurely axially ribbed; these whorls show little increase 

 in size, giving the shell a mucronate appearance; spire 

 whorls rounded; suture well impressed; aperture ob- 

 liquely oval; canal open, of medium length; outer lip im- 

 perfect; the sculpture indicates a large, shallow sinus at 

 the carina; columella arched above; the enamel of the 

 inner lip spreads well out on the base of the shell. The 

 sculpture consists of two rows of rounded tubercles 

 separated by a depression, but connected by a low axial 

 ridge between each; there is also a roughly nodulous rib 

 below the suture; the nodules are comparatively larger 

 and more distinct on the spire; on the body whorl the 

 lower row becomes increasingly less distinct, and there 

 are several plain keels on the base. 



Length, 21 m.m.; breadth, 8 m.m. ; length of aperture, 

 9 m.m. 



Locality ; Type from 40 fathoms three miles east of 

 Schouten Island, with four others, all imperfect. I have 

 placed it with Hemipleurotoma because of the sinus at the 

 carina, but possibly the canal is somewhat long. It has 

 an obvious resemblance to H. quoyi, from which, how- 

 ever, it is sufftciently distinct, both by its sculpture and 

 the peculiar peg-like apex. 



DRILLIA SCHOUTAXICA, X.S. (PL. XIV., 

 FIG. 17.) 



Shell pure white, turretted, subfusiform ; whorls seven, 

 including a blunt protoconch of two smooth rounded 

 whorls; spire whorls convexly angular, girt with a row 

 of distant nodules at the periphery, and a smaller row at 

 the suture, on the lower part of the whorl is a somewhat 

 nodulous keel, and between the two upper rows on the 

 flatly sloping shoulder are four narrow raised lirse. The 

 body whorl has about 1 5 lirae on the base, the first, oppo- 

 site the suture, being nodulous; some of these lirse form 

 ridges Vv-ithin the aperture; mouth squarely oval, opening 

 into a short wide canal; lip thin, angled at the upper
