«Testa late flabelliformis, rotundata, crassa. Valva sinistra convexa, laevigata, concentrice levissime laminata, carneola, fasciis irregularibus undulatis rufo-fuscis et carneo-albidis picta, costis 20, rotundatis, haud striatis, auriculisque latiusculis, complanatis, striatis, subaequalibus instructa. Valva dextra minus convexa, costis paulo latioribus. Long 110, alt. 120, lat. 45 mm.
Hab.— Kurachi. The type is in the collection of Mr. J. J. MacAndrew. This fine shell was discovered by Mr. F. W. Townsend, after whom I have much pleasure in naming it. There is another specimen from the same locality in the British Museum (Natural History). Compared with P. crassicostatus, Sowerby, it is rounder, the left valve more convex, the auricles more nearly equal, and the ribs much less numerous, not angular or squamose, but smoothly sloping. Neither ribs nor interstices have any longitudinal striae.» GEORGE BRETTINGHAM SOWERBY III, 1895

«Material:— Sample Qm.903 (4 miles N. of Lingeh; Pecten vasseli Beds (Pliocene)), 3 specimens (including L.86096-7); sample MN.231 (Shir; Pliocene), 1 specimen.
Remarks:— The specimens, which are about 150 mm. high, are of the same size as the largest Recent specimens in the British Nluseum (Natural History) and larger than the holotype, which is 120 mm. high. Their ribs (about 27) are rather more numerous than in the Recent-specimens, in which the number is 20 or 21, but the general character of the ribbing and the shape and ornament of the auricles is similar. So far, this species has been found living only at Karachi, the type locality, where Winckworth has recorded specimens as large as 196 mm. x 197 mm.» EAMES, F. E. & L. R. COX. 1956.
