U. obliqui-radiaius is nothing but a female U. radiatus, 

 Lam. U. auratus, Swains., and U. fragilis, Swains., both from 

 the Island of Chiloe, appear to me to be the same species.

We hope that Mr. Sowerby will find sufficient encourage- 

 ment to proceed with the publication of "Conchologia Iconica," 

 now threatened with discontinuance, in consequence of the 

 recent deaths of Hugh Cuming and of its author and pub- 

 lisher, Mr. Lovell Reeve.
