Venus alla Sowerby is undoubtedly synonymous with Chione [Claîisinella) foliacea (Philippi), 

 while Sowerby and Reeve hâve regarded the latter species of Philippi as a synonym of C. (C) 

 tiara (Dillwyn). Dautzenberg, on the other hand, in his récent work remarked "mais cette 

 assimilation est fort douteuse car les figurations de Born, Chemnitz, etc., citées par Dillwyn 

 représentent des coquilles plus grandes et ornées de lamelles beaucoup plus espacées". I am 

 unable to accept the above view, as in large collections from any area the spécimens of this 

 species vary according to âge and size, both in respect to the form of the shells and the 

 lamellar projections on them. 



Distribution : — C. (C) tiara) lias a wide range in the Indo-Pacific and has also been 

 recorded from the Red Sea and the Persian Gulf. 



In the "Siboga" collection it is represented by shells collected at the Anchorage off 

 Djangkar, Java (St. 4), Bay of Pidjot, Lombok (St. 33), Kambaragi Bay, Tanah Djampeah (St. 64) 

 and St. 319 (6° 16'. 5 S., ii4°37'E., 82 mètres).

Klein's pre-Linnaean name Anomalocardia ') does not invalidate Schumacher's genus of 

 the same name, and 1 hâve, therefore, with Deshayes and Dall adopted it in préférence to 

 Cryptogramma Morch. 



The génotype is Anomalocardia jiuctuosa (Linn.). Dall proposed a new section Anomalo- 

 disciis (loc. cit., p. 359) for the Indo-Pacific form Anomalocardia {Ano?7îalodisctis) sgtiajnosa {]Jinn.), 

 in which the surface of the shell has a reticulate, subequal sculpture, and the hinge is without 

 rugosities.
