carinse, and riblets finely transversely striate througliout ; 

 aperture entire, ending in short canal ; outer lip denticulate 

 interiorly. Long, about 22mil., lat. 8. Rare, Table Cape. 

 This shell, though smaller, approaches very close to T. tor- 

 tuosum, Reeve. I have, unfortunately, broken the aperture 

 after it was partly described. 



MiTEA ANTICORONATA, n.S. 



Shell small, narrowly ovate, rugose ; whorls 7, sloping, 

 slightly convex, spirally niultihrate (12 on last whorl) ; lirae, 

 regularly sub-distant on upper portion of whorl, but become 

 more and more distant as they approach base ; lirse inter- 

 sected by sharp lirae-like riblets (25 on last whorl), giving a 

 cancellate appea^rance to the shell, and becoming slightly 

 granulose at points of intersection ; suture faintly impressed ; 

 aperture ovate, scarcely exceeding the spire ; anterior canal 

 pointed, narrow ; columella quadriplicate, the two central 

 folds being most prominent. Long. 13, lat. 5, long, apert. 7, 

 lat. 2. Rare (one specimen), Table Gape. This unique 

 shell approaches nearly to M, coronata, Lamarck. It is much 

 smaller than the Mitra granatina, Woods and Swainson, 

 which latter name must be altered, as a very similar shell has 

 been described and so named by Lamarck, and is figured in 

 Chenus* Manual of Con. 



Pyeamidella polita, n.S. 



Shell minute, white, turreted, shining ; whorls, 6f , smooth, 

 flattened ; under 1-inch object glass, very fine longitudinal 

 lines are visible, crossed with fine wavy lirse ; base of last 

 whorl somewhat truncate, with an indistinct sub-angular 

 keel ; nucleus exserted, sub-central ; aperture auriform, 

 rounded and slightly expanded anteriorly ; inner lip twisted 

 back plait-like over columella, and forming a deep regular 

 spiral channel behind ; outer lip continuous with the plait- 

 like inner lip, simple. Length 4mil., breadth l|mil. Rare, 

 Table Cape. 



RiNGICULA LACTEA, n.S. 



Shell white, shining, minute, conical, sub-turreted, of about 

 6 rapidly-increasing whorls ; whorls convex, ornamented by 

 regular, distant, punctate, spiral sulci, about 12 on last 

 whorl ; under lens broad distant obsolete transverse lirse may 

 be traced ; suture deeply impressed ; columella abbreviate, 

 with two thick tortuous folds, the lower being the largest ; 

 aperture roundly notched posteriorly and anteriorly ; outer 

 margin thick and reflexed, forming a broad varix continuous 

 with the last tortuous fold of columella. Long. 6mil., lat. 

 3mil. Rare, Table Cape.
