Ann. Mag. N. H. (5), vi, p. 318 ; Rep. Br. Asso., 1873, p. 114, as 

 Utriculus striatulus. See Nuova Ri vista, p. 48, and Journ de Conch. 

 1874, p. 281. 



Still undescribed, unless the preceding note by Monterosato be 

 called a description ; and originally mentioned as a Utriculus by in- 

 advertence. Reported thus far from off coast of Algeria 207 fms. 

 (Jeffr.), Palermo and St. Vito, 90-200 meters (Monts.), and Bay of 

 Biscay (Jeffr.).

P. INFUNDIBULUM Dall. Unfigured. 



In the multiplicity of species of Philine this one is best described 

 by a comparative diagnosis. The soft parts externally are whitish, 

 and resemble P. quadrata and P. finmarchica as figured by G. O. 

 Sars. It is nearest P. quadrata so far as shell characters go, and 

 belongs to the group of species which have the spire entirely im- 

 mersed and the posterior junction of the outer lip descending upon 

 it in a sort of spiral. The shell is thin, pellucid, and finely closely 

 spirally striate. It differs from that of P. quadrata chiefly by its 

 larger size and the much smaller proportion wrapped in the body- 

 whorl. The soft parts though larger, are remarkably like those of 

 P. quadrata, but in that species the ventricular plates are wanting. 

 In the present species they are present and of large size, the large 

 (right) plate being lozenge-shaped, whitish and slightly concave on 

 the side of insertion, covered with a convex, polished nearly smooth 

 brown coating on the interior, which is generally worn away by 

 friction toward the center. The small plates are nearly the shape 

 of half the large one partly hollow and without granules. They 

 resemble on the whole, the plates of P. angulata Jeffreys as figured 

 by Sars (loc cit., t XII, fig. lOd), but are larger, longer, and more 

 pointed at the extremities. The adult shell comprises about two 

 whorls, maximum length 12'0, max. breadth 9'0 mm. The large 

 plate measures about 4'0x8'0 mm. The axis of the shell is wound 

 in a wide pervious spiral, and the body-whorl viewed from below 

 extends about half way across the base from side to side, and two- 

 thirds the distance from the apex to the front edge. (Dall, Blake 

 Gastr., Bull. M. C. Z., xviii, p. 57, 1889).
