Abstract

IN a recent communication (Mahadevan 1959) attention was drawn to an interesting association of the pearl fish Fierasfer homei (Richardson) with the wing mussel Pteria sp.,** found in the Gulf of Mannar off Tuticorin. A re-examination of the pearl fish showed that the position of the vent is at the base of a line just behind pectoral origin and the origin of the dorsal is in a line above the middle of pectoral (Plate, 1, Fig. C). Further, other distinguishing characters of this fish described elsewhere in this account justified the earlier doubts (Mahadevan op. cit.) of the likelihood of its coming under Carapus (syn : Fierasfer) margaritiferae (Rendahl), a brief account of which is given by de Beaufort (1951) based on specimens collected from Pulu Punga, Pulu Missa, coast of Flores and Cape Jaubert N. W. Australia, mostly in association with the wing mussel or sometimes with a holothurian. Smith (1955), while reviewing the family Carapidae has mentioned the occurrence of C margaritiferae in South African waters also where three specimens, 75-93 mm. in length, were ' taken from inside clams at Durban.' The data on two specimens of 63.5 and 85.0 mm. examined by the present author indicate differences in some of the characteristics as compared with the South African form described by Smith. In order to facilitate comparison of the Indian form with others occurring elsewhere a detailed description of the material in hand is given below.
