Cox includes Ostrea imbricata Lamarck in the synonymy of O. (Z,.) hyotis, as had also 

 been suggested by Deshayes and several of the earlier v^orkers. Dunker, Reeve, Pilsbry, Lynge, 

 Melvill, Dautzenberg consider ^ it as quite distinct. I hâve carefully examined the available 

 material, and am of opinion that it can be distinguished as a distinct variety. 



The shell of the var. imbricata is usually thinner, the pHcations of the valves more 

 numerous and angulate and the hinge-Hne more extensive. 



Distribution : — - O. [L.) hyotis var. imbricata has been recorded from Japan, China, 

 New Guinea, Java, Mekran Coast and the Persian Gulf 



In the "Siboga" collection this variety is represented by a single adult spécimen collected 

 from the Ambon Reef
