agree with typical specimens of that species from Hong Kong. 

 I consider that it is an example of R. doliaris with an unusually 

 thickened lip. So R. arctata Gould, can be eliminated from the 

 fauna of this State.

In the British Museum are two specimens of T. brenchleyi 

 Angas, from 10 faths., Sydney, presented by J. Brenchley, in 

 1873. Though not so marked, these are obviously the types of 

 Angas. They seem to me to be identical with the types, four 

 specimens, of T. avenarius Watson, collected by the Challenger 

 Expedition, in 10 faths., Sydney. With these agrees a photo- 

 graph of T. apicina Gould, from the same habitat, kindly taken 

 for me from the type in the National Museum, Washington, by 

 Dr. Paul Bartsch. 



From the China Sea are six shells marked, in the British 

 Museum, as the types of Tornatina fusiformis A. Adams. These 

 have an upright, projecting, heterostrophe apex, and arcuate 

 longitudinal riblets. I think that Angas was mistaken in identi- 

 fying this with an Australian shell. Cook* considered that 

 T. fusiformis was T. olivaformis Issel.

In the British Museum, I noticed five, marked " types C. 

 decussata A. Adams, Thes., &c, China Seas. M.C." These ap- 

 peared to me like R. impasta, so that, after my return to Sydney,
