 Philippia liilea. Gray.

 of the Mediterranean and Australia.

 Solarium oxylropis, Hanlev. 



Ilab. New Caledonia. 



Mr. Cuming's specimen of -S". oxylropk is an immature 

 shell, but it is the young of a very diti'erent species with 

 tliat to \vluch it has been assigned, .S'. hybridum. It is a 

 depressly discoid shell, of light structure, encircled at the 

 periphery with a conspicuous keel, not beaded, but smooth, 

 studded with faint red dots.

Hab. ■ ? 



This shell was selected by ilr. Hanley for publication 

 in his recent monograph of tliis genus in Mr. Sowerby's 

 ' Thesaurus Conchyliornm,' but accidentally mislaid during 

 its preparation, and not therefore included. The two 

 belts of spots and dots are both characteristically cut 

 through or duplicated by a spiral linear groove.
