by about fourteen of these transverse liroe, whereof nearly all, with 

 the exception of a few at the base, are more or less granular on the 

 plicae. Aperture equalling about two fifths of the entire length of the 

 shell, Hght brown ; fissure in the lip, below the suture, and above the 

 nodulous angle, broad and moderately deep ; labrum thin, prominent 

 in the middle, with a very shallow sinuation near the base, smooth 

 and not lirate within ; columella callous at the base ; canal very 

 short. Operculum elongate, rather acuminate at both ends ; nucleus 

 terminal. 



Length 18^- millims., diam. 6 j. 



Hab. Station 29. Also China Seas {Mus. Ciimincj). 



The style of sculpture of this species is' considerably like that of 

 P. metcalfei, Angas. However, the whorls are fewer, the nuclear 

 one being larger, the last proportionally broader. The few lirations 

 within the lip of that species are wanting in the present one ; and the 

 tubercles around the middle of the whorls are less oblong than in P. 

 metcalfei. 



\7. Drillia peradmirabilts. (Plate XIX. fig. 12.) 



Shell robustly fusiform, whitish or yellowish white, stained with 

 brown beneath the suture, and obscurely banded with the same 

 colour about the middle of the last whorl, spotted and dotted with a 

 lighter tint irregularly over the rest of the surface, but leaving a 

 plain white zone at the angulation of the whorls and a second just 

 above the median brown one on the last whorl ; apex white. Volu- 

 tions 8^; one and a half nuclear smooth, globose; the rest concavely 

 sloping above, then obtusely angled about the middle, rounded, and 

 much contracted beneath, obliquely plicated and spirally lirated ; 

 plicoe rounded, oblique, but little elevated, more or less obsolete at 

 the upper part. Transverse lirae most beautifully and finely granu- 

 lated, separated by deep-cut striae of different sizes, those in the 

 concavity of the whorls subequal and finer than those beneath, which, 

 again, are not all of uniform tenuity ; on the penultimate wiiorl 

 they number about 20, and on the last as many as 55 ; those around 

 the lower part of the last whorl are pretty regularly alternately 

 larger and small, the latter being the more granulous. The body- 

 whorl is contracted at the lower part, and is destitute of the plicae 

 on about a third of its extent near the lip. x'Vperture together with 

 the canal a little less than half the length of the shell, brownish 

 within, with a single white central zone, and a white patch parallel 

 with the margins of the lip, corresponding to a stout exterior sub- 

 marginal varix, and stained with dark brown between this and the 

 thin prettily crenulated edge of the labrum, which is curved and very 

 shallowly sinuated towards the base, and finely sulcated within, but 

 at the edges ; sinus deep, at the suture ; columella a little oblique and 

 tortuous, whitish, without markings or callosity, only furnished 

 with a small whitish tripartite tubercle at the upper part, just a little 

 below the sinus, and connected with the suture by a thin callus. 



Length 23 millims., diam. 7|.
