pyramidal, nucleus of two smooth turns, apex blunt, 

 whorls (without nucleus) 8, flattened, with 20-24 straight 

 round ribs which continue unaltered (though some- 

 times slightly flexucus) from suture to suture ; interstices not 

 so wide as the ribs, and very closely spirally grooved, which 

 sometimes pass over the ribs; base roundly convex and 

 spirally Urate, suture submarginate, aperture broadly ovate, 

 outer lip thin, columella slightly arched, canal short, very 

 slightly recurved. Long. 5f , Lat. 1|. 



EuLiMELLA stJBULATA. Douovan. {Ncit. Hist. Brit. Shells, 

 vol. 5, t. 173 — 1799 as Turbo.) This shell, which is very fully 

 described and figured by Homes, Nyst, Wood, and others, as 

 Eulima, would come under Prof. Forbes genus of Eulimella. 

 It has received a host of names during the last 11 years of its 

 scientific life. I can see no difference whatever between the 

 specimens found at Table Cape and those found existing in 

 the British seas. It is extensively known as European 

 Miocene and Pliocene fossil. Not common. Two specimens 

 forwarded by R. M. Johnston, one by — Stephens, many 

 found by myself at Muddy Creek, Victoria, Mordialloc, etc. 

 It has not yet been found living in Australia, unless some 

 only closely allied forms of Eulima should be identified with it. 



AcTiEON scEOBicuLATUs. U.S. Shell oblong, ovate, solid, 

 apex acute, smooth only at the extreme summit, whorls 7, 

 cancellate with very distinct spiral lirae, much finer longitudinal 

 strise ; interstices rounded or punctate, lirse on the last whorl 

 broad and subdivided by a fine groove, longitudinal strise sub- 

 distant (so that the interstices are transversely oblong) and 

 passing occasionally over the liree, so as to make them sub- 

 granular, especially at the anterior margin ; aperture 

 subaurifoi'm, posteriorly acutely attenuate, peristome anteriorly 

 everted and recurved, plait conspicuous, solid, obtuse. Long. 

 12, Lat. 6, apert. 6. 



A form very closely allied to the A. inncjids, D'Orb., of the 

 European Miocene, from which it differs in the narrower 

 form, the character of the plait, the anteriorly produced mouth 

 and everted lips. It has no Tasmanian nor Southern Aus- 

 tralian congener. 



Cylichna arachis. Quoy. Still living in Tasmania and 

 Australia, and not uncommon in the Table Cape beds. 



Liotia discoidea. Reeve Zool. Prov., 1844. Living in 

 Tasmania and extending to Philippines; somewhat small in 

 the fossil state and rare. 



FissuRELLA concatenata. Crosse. Shell thin, oval, 

 laterally and anteriorly depressed, tumid posteriorly, irregu- 

 larly concentrically ridged with lines of growth, and covered 

 all over with fine hexagonal depressions which grow broader
