As Smith has shown, Cooke was certainly wrong- in including in the synonymy of 

 V. spongiaruin the species V. pholadiformis^ V. isocardia^ V. crenulata^ V. trita^ V. dilatata 

 and V. hugeli. The synonymy of the species given above is mainly dravvn up from Smith, but 

 I hâve satisfied myself about its correctness. 



Distribution : — l\ spongiaruin has been recorded from the Austrahan and Tasmanian 

 waters and from the Seychelles. 



A complète shell was dredged by the "Siboga" Expédition at St. 164 (i°42'.5S., 

 130° 47'. 5 E., 32 mètres) and a single valve in the Bay of Bima (St. 47).

For a good description of Pteria Scopoli référence may be made to Woodring's paper 

 cited above. The génotype is Pteria hirundo (Linn.). 



In the "Siboga" collection I hâve not been able to refer 3 forms to previously described 

 species; thèse are described in the présent work under the names P. toinlini, P. triangiilaris 

 and P . sibogae. Some shells are very young and, therefore, unidentifiable, while two badly broken 

 shells from Bay of Bima (St. 47) appear to be young spécimens of Pteria heteroptera (Lam.) ^).
