REPOET ON THE GASTEROPODA. 571 



to a sharp point above, and at the front of the pillar. Outer lip thin and sharp, con- 

 tinuously and evenly arched throughout. Inner Up short and barely convex across the 

 body, openly concave at the base of the pillar, which on the left is rounded and twisted 

 with a minute umbilical furrow in the middle behind the sharp small slightly reverted 

 pillar lip, which, as well as the pillar itself, are fined off to a sharp point short of the 

 extremity of the shell. H. 0'07 in. B. 0-044. Penultimate whorl, height 0'013. Mouth, 

 height 0'039, breadth 0-023. 



In the solitary specimen of this species the outer lip is a little broken, which gives the appearance 

 of a canal, but the lines of growth show that this appearance is deceptive. At the same time I do 

 not feel at all certain that this is a Stiliferina ; it may be only a young shell of some other genus, 

 but the whole group would need more study than it has yet received, and I greatly doubt whether 

 the genus or subgenus has, even after the changes it has already undergone, found its true place in 

 classification . 



7. Alaba (Stiliferina f) fulva, n. sp. (PI. XLII. fig. 5). 

 September 7, 1874. Off Cape York, Torres Strait. 3 to 4 fathoms. 

 Station 186. September 8, 1874. Lat. 10° 30' S., long. 142° 18' E. Off Wednesday 

 Island, near Cape York. 8 fathoms. Coral mud. 



Shell. — Strong, elongate, curvedly conical, mucronate, fulvous, 1 ribbed and spirally 

 striate, with oval mouth, longish body- whorl, and impressed suture. Sculpture : Longi- 

 tudinals — there are on each whorl from 18 to 20 small, feeble, rounded riblets, parted by 

 shallow and broader furrows ; on the upper whorls these extend from suture to suture, on 

 the last whorl they die out on the base ; they do not appear on the first two normal 

 whorls below the style. Spirals — on the penultimate whorl there are eight slightly rounded 

 threads, of which the third and sixth are very slightly stronger than the rest ; on the base 

 there are about four more, of which the last closely entwines the pillar; the parting 

 furrows are of about the same breadth and strength as the threads. Colour dark yellow. 

 Apex consists of two turbinated smooth whorls, of which the second is rather broader 

 than the first regular whorl. Spire high and conical, with convex profile lines. Wliorls 

 10 (exclusive of the style), convex, short, and broad, only the last being a little elongated, 

 with a rounded base. Suture strong, coarse, impressed and almost horizontal. Mouth 

 oval, pointed above ; the whole base at the front of the mouth is very obliquely cut off 

 backwards. Outer lip sharp and thin, very regularly curved all round ; it is cut off back- 

 wards across the whole base. Inner lip concave throughout, thin, appressed, very obliquely 

 cut off in front, but not so as to produce a truncated point to the pillar ; there is across 

 the body a faint trace of a layer of shell connecting the outer and inner lips. H. 0'13 in. 

 B. 0-045. Mouth, height 0-033, breadth 0-024.
