Eulima ague, Angas ! is correctly named.

Ataxocerithium serotinum (A. Ads.), Tate, J. Roy. Soc,

 the type of a new genus.

Quoy and Gaimard's types which I have studied were obtained 

 at Port Western, Victoria ; the species is very common in Tas- 

 mania and South Australia ; it inhabits the mud-flats in the 

 region of about half-tide. Its operculum is circular and many 

 whorled. 



This shell has been misquoted by Menke and subsequent 

 authors, which is traceable to a confusion of Quoy and Gaimard's 

 own creation ; thus they describe and figure a shell from Port 

 Dorey in Papua as Cerithium turritella (t. 55, f. 8), whilst the 

 Victorian shell is called Turritella cerithium. The Southern 

 shell is the latter, and it extends to West Australia, if my quo- 

 tation of Menke is right, who, however, mentions only the name, 

 but adds a reference to Kiener, Icon. p. 64, t. 22, f. 1, which I 

 cannot consult. 



The generic name Batillaria, Benson, 1842, replaces Lampania, 

 proposed four years after by Gray. 



Triforis Angasi, Crosse !, is rightly identified. 



Diala monile, A. Adams !, is rightly identified, though the 

 types are immature ; T. tessellata, Ten. -Woods !, better exemplifies 

 the species than the commoner form in South Australian waters. 



Diala lauta, Adams !, is rightly identified. 



Littorina Mauritiana, Lamarck. The smaller and rotund 

 variety, which lives at the high-water-mark is L. Diemensis, 

 Quoy and Gaimard !. 



Paludinella Gilesii, Angas !, P.Z.S., 1877, t. 26, f. 2, 171, was 

 redescribed by me, Trans. Roy. Soc. S. Aust., vol. XVI., p. 196, 

 under the name of Blandfordia Stirlingi, an excusable over- 

 sight on account of the faulty figure, which better represents 

 Bithynia australis. The present species may be quoted as 

 Blandfordia Gilesii.
