Angas (G. French, C.M.Z.S., &c.) — Descriptions of two 

 genera and twenty species of marine shells from 

 New South Wales. — P. Z. S., 1877, p. 34 to 40 and 

 plate V. 



The two new genera are Microvoliita and Cirsonella — the 

 latter of which is placed provisionally among the Trochida: it 

 differs from Crossea A. Ad., Puiilla A. Ad., Microthyca A. Ad., 

 and Umbonella K. Ad., by characters which are pointed out. The 

 new species are Purpura ( Crotiia) anomala, Microvoluta austral is, 

 Columbella (Anachis) speciosa, Turbonilla /estiva, Cingulina 

 Brazieri, Apicalia Gicentheri, Cerithiopsis purpurea, Conus 

 ( Stephanoco?ius ) Sniithi, Drillia amiila, Mangelia Jacksonensis, 

 M. flavescens, Clathurella Brenchleyi, C. ritfozonata, C. pustulota, 

 C. modesta, Cirsonella australis, Ethalia Brazieri, Myonia 

 sifiuata, Tornatina Hofjnani and Tornatina Brenchleyi. 



Angas (G. French, C.M.Z.S., &c.)— Descriptions of a new 

 genus of Gasteropodous moliusca from Japan, 

 and of a new species of Bullia from Kurrachi.— 



P. Z. S., June 5, 1877, PP- 529 and 530 and plate liv. 



The new genus Thatcheria cannot as yet — in the absence of 

 a knowledge of the operculum — be allocated to its precise generic 

 position; but is for the present referred to the sub-family Fusijice. 

 The new species — T. mirabilis — is founded on a unique example 

 from the Japan seas. The new species of Btillia—B. (Leio- 

 donius) Kurrachensis, was collected by Mr. Angas' daughter at 

 Kurrachi.
