REPORT ON THE GASTEROPODA. 221 



7. Phos smithi, n. sp. (Plate XVII. fig. 7). 



Station 122. September 10, 1874. Lat. 9° 5' S., long. 34* 50' W. Off Pernam- 

 buco. 350 fathoms. Mud. 



Shell. — Long, narrow, fusiform, closely and narrowly ribbed, spiralled, with a high 

 narrow spire of flatly convex whorls, a small sharp apex, a shortish conical base, termi- 

 nating in a short, lop-sided, straight snout. Sculpture: Longitudinals — there are on the 

 last whorl 18 or 19 ribs, which diminish slowly in number up the spire; they stretch 

 from suture to suture, are more or less continuous from whorl to whorl, and extend to 

 the snout ; they are narrow but well rounded, though on the last whorl they tend a 

 little to spread out and flatten ; the furrows between them are rather broader than they, 

 especially on the body-whorl, for towards the apex they are crowded ; on each whorl one 

 or two of these ribs swell into a slightish varix : the entire surface is densely covered 

 with fine hair-like lines of growth. Spirals — the whole shell is scored with rounded 

 threads a good deal finer than the ribs; of these there are 2 on the first regular 

 whorl, 7 to 8 on the penultimate, and about 1 6 on the body-whorl ; in crossing the 

 ribs these threads rise into broadish compressed white tubercles ; the furrows between 

 the threads are more than double the breadth of these, but generally have a finer thread 

 in the bottom ; two of the threads at the periphery, and the two on the snout, are 

 stronger than the rest ; the point of the snout is scored with the old canal scar, and 

 is streaked obliquely with narrowish threads. Colour an ochrey white, stained with 

 three bands of pale chestnut brown. Spire high, narrow, conical. Apex is sharply 

 conical, and consists of 4 small white carinated angulated whorls (the extreme tip is 

 broken, but was evidently minute), of which the last is feebly ribbed longitudinally. 

 Wlwrls 8 below those of the apex ; they are short and convex, and of very slow 

 increase ; the last is small and narrow, and has a short rounded base, ending in a 

 smallish, lop-sided, slightly twisted, barely reverted, emarginate snout. Suture a little 

 impressed, rather oblique. Mouth small, oval, pear-shaped, prolonged into a very short 

 oblique canal. Outer lip thin, flatly convex in its curve, patulous in front, where it 

 becomes concave in its curve, and then it runs oblique and direct down the short canal. 

 Inner lip narrowly excavated into the texture of the shell ; it is flat on the body, concave 

 at the base of the pillar, which is short, straight and feebly double-toothed at its point, 

 where it is obliquely cut off and twisted. H. 1'25 in. B. 0"45. Penultimate whorl, 

 height 0-23. Mouth, height 0"52, breadth 0"25. 



This species a good deal resembles Phos mmingii, Reeve, in form, but the sculpture is quite 

 different. I have given it the name of Mr Edgar A. Smith, whose ever kind help I have 

 repeatedly had to appeal to.
