less tumid, and the outer lip does not, as in that species, rise 

 above the crown except, and but occasionally, in the very young 

 shell : the sculpture too is quite different. 



4. Philine teachyosteaca, n. sp. (rpaxvoorpa/cos, rough- 

 shelled.) 



Shell oval, hut slightly truncated across the top, flattened, 

 thin, translucent, very rough and fretted on the outside surface. 

 Sculpture : the whole surface is very harshly roughened by a 

 network of coarse, sharp, narrow, unequal projecting bars, which 

 give a crusted appearance to the shell ; where this network is 

 rubbed off the surface of the shell appears like frosted glass 

 fretted in squares : the longitudinal bars run on the lines of 

 growth, those which cross them are spirals. Colour : the surface 

 made up of the bars is dead dirty white. Spire : a little sunken ; 

 in the bottom of a small, open, funnel-shaped depression is the 

 mammillary apex, round which coil two whorls. Suture barely 

 impressed. Mouth pear-shaped, rather small. Outer lip rises 

 shortly, makes a short and narrow curve at the top, runs down 

 with a hardly prominent edge and but slight curve to the base, 

 where it sweeps round freely (but is barely patulous) to join the 

 point of the pillar. Inner lip : down the body from well inside 

 the mouth this lip projects as a narrow square-set shelf, which 

 dies off on the straight longish sharp-edged pillar, which is 

 slightly truncate at its point. — L. 0*11. B. 0-07. 



Of this curiously marked Fhiline I got only two specimens, 

 one of them young — both from about 50 fms. Punchal Bay. 



5. Philine desmotis, n. sp. (Seo-juwns, enchained.) 

 Shell rhomboidal, but with the upper left-hand corner rounded 

 off; flattened, thin, but not fragile, horny, hardly glossy. Sculp- 

 ture : there are many unequal and somewhat irregular lines of 

 growth, coincident with whose curves are very fine microscopic 

 lines which seem to pervade the substance of the shell ; crossing 

 these nearly at a right angle are impressed chain-like lines 

 whose links are 3 to 4 times as long as they are broad, towards 

 the lower edge of the shell these links are more and more elon- 

 gated, the raised surfaces between the chains are slightly wider 

 than the chain lines, and project on the edge of the shell which 

 they crenellate strongly above, more feebly but still more or less 

 traceably, especially in the young shell, all along its whole edge ; 

 a slight translucent pad encircles the top of the shell. Colour
