38 PEOCEEDINGS OF THE MALA.COLOGICAL SOCIETY. 



growth-strise are visible in the interstices ; the cingula on the third to 

 fifth whorl are faintly nodulous, but those on the later whorls remain 

 smooth. Colour light yellowish-white. Spire high, sub cylindrical, 

 much higher than the aperture ; outlines straight. Protoconch pauci- 

 spiral, globose, of two smooth and convex whorls. Whorls about 6, 

 regularly increasing, very little convex ; base smooth, slightly 

 concave. Suture not deep. Aperture subquadrangular, with a short 

 and open canal below. Outer lip sinuated by the spiral sculpture ; 

 basal lip almost straight. Columella subvertical, nearly straight, 

 narrowing to a point below. Diam. -8, height 2*5 mm.

Shell small, acicular, slightly polished, rather fragile. Sculpture : 

 the first whorl smooth, the next one or two with two keels, succeeding 

 whorls with three, the last with four keels and one upon the base ; 

 sometimes the last two to four whorls bear four keels, the lowest of 

 which, however, may be reduced to a suprasutural thread ; the axial 

 sculpture is very variable: fine growth-lines in the interstices between 

 the keels, or distinct threads passing over the keels, very often 

 rendering them moderately nodulous. Colour light brown. Spire 

 high, subcylindrical ; outlines straight. Protoconch of one broadly 

 convex whorl. Whorls about 1 1 , regularly increasing, almost flat. 

 Suture not much impressed. Aperture broadly oval, vertical, angled 

 above, produced below into a short, slightly recurved, and narrowly 

 open canal, its base not emarginate. Outer lip sharp, sinuated by the 

 spiral sculpture. Columella short, perpendicular, bent off and drawn 

 out to a point upon the inner margin of the canal. Diam. r5, 

 height 5-25 mm., one of the types with 11 whorls. 



Hah. — Stewart Island, in 30 fathoms, type ; Whangaroa Harbour 

 (C. Traill) ; near the Bounty and Snares Islands, in 50 fathoms 

 (Capt. BoUons). 



The specific name minima being preoccupied in Triphora by Pease, 

 1870, I change it to T. Huttoni. The nearly allied Australian 

 T. Angasi, Crosse, has a much more prominent axial sculpture, the 

 cingula are gemmate, and the base has two keels. T. Kesteveni, 

 Hedley, from Sydney Harbour, is another nearly related form. Type 

 in the Colonial Museum, Wellington. 



49. Tkiphoea eascelina, n.sp. PI. Ill, Pig. 49. 



Shell small, slender, and narrow. Sculpture : the polygyrate 

 protoconch has the first whorl smooth, the second microscopically
