a very distinct little species. I place this in H ninnlHi 

 with some diffidence, but it seems to come closer to such 

 species as //. .^raiigri than any other forms. 



PI. XV.. fig. 16. 



AjII'lllTH.VL.VMUS LUTEOFUSCUS, Sp. nOV. 



Shell minute, turbinate, smooth, lustrous red-brown, 

 with the first half of the body whorl and mouth, yellow, 

 also a light band below the suture. Whorls four, much 

 rounded, body whorl large in jDroportion. Aperture : 

 The actual opening is small, oval, and set very obliquely 

 to the spire; it is surrounded by a raised edge or keel. Tho 

 peristome, which is continuous, is broadly pyriform. ex- 

 panded and planulate, recessed towards the aperture ; it 

 IS projected somewhat from the base of the shell, which 

 is sub-umbilicate. The operculum is thin, semi-trans- 

 parent, and appears to bo subspiral. 



Length, 1 ; Ineadlh, .6 mill. . 



Habitat. Type, with several others, from Kelso, near 

 Tamar Heads, collected by Augustus Simson. 



This minute shell is in size and general appearance 

 similar to A. Jorlsonl, Brazier, but differs sufficiently in 

 the detail? of the mouth, and also in the coloration; it is 

 in some respects still more like A. (ifinjnir/titrfa. That, 

 however, is a much more ventricose and massive shell, 

 which does not seem to have been heretofore recognised 

 as a member of this genus, although it is extremely 

 characteri.-tic, and closely allied to A. jdckatmi.

NOTOSETIA PURPURE0.STOMA, Sp. UOV. 



Shell minute, bluntly turbinate, smooth, polished, 

 pale I'ose colour, lip rose-purple. Whorls three, much 

 rounded, suture impressed. Aperture, roundly oval, lip 

 continuous, with a thickened edge, and reflexed on the 

 columella side. 



Length, 1 ; l)readth, .8 mill. 



Type, with a dozen others, fi-om Penguin, in shell 

 sand. It has a superficial resemblance to Anijihifhaldmii'^ 

 (ifropnr/titreo. Frauenenfelt, from which the latters typical 

 aperture at once separates it.

Rissopsis BREVis, .?p. nov. 



Shell very small, cylindrical, blunt, smooth, puro 

 white, pellucid. Whorls, four and a half, rather rounded,
