As RoMER pointed out P. {P.) undulata is closely allied to P. [P.) textile (Gmelin), but 

 the latter species has a thinner, higher, more inflated and elongated shell with the anterior 

 dorsal margin less concave and the posterior dorsal margin more oblique. The valves of P. [P.) 

 undulata^ further, hâve a sculpture consisting of well marked, though not deeply impressed, 

 irregular concentric ridges particularly on the anterior part and the lower half of the shells. In 

 old or worn shells the valves hâve an almost smooth surface. 



Distribution: — P. {P.) tindulata has a wide range in the Indo-Pacific; it has been 

 recorded from the Persian Gulf, Ceylon, Mergui Archipelago, Gulf of Siam, Arafura Sea, 

 Australian waters, the Philippines and Chinese and Japanese seas. 



In the "Siboga" collection it is represented by a number of shells from the Bay of Labuan 

 Tring, west coast of Lombok (St. 19), Macassar (St. 71), Saleyer Anchorage (St. 213) and the 

 Anchorage off Noimini, south coast of Timor (St. 296).
