Plate 15. Tellina (Cadella) semen Hanley. Fig. 1. External view of the left valve, Durban, NM 1809 (length = 18 mm). Fig. 2. Internol view of the right valve, Durban, NM 1809 (length = 12.1 mm). Figs. 3 and 4.

This morphological configuration indicates the relationship of the Tellinidae with the Semelidae; the latter nomially have a larger conspicuous internal resilium supported by a well- developed chondrophore. Striking similari- ties are most evident bet\\een CadcIIa and the various species of the semelid genus Semehin^iihis. as noted bv Dall. Bartsch, and Rehder (193S). Another variable morphological char- acteristic exhibited in populations of T. semen is the nature of the concentric sculpture along the posterior slope in the right valve. Usuallv the concentric lirations become stronger, somewhat raised, and sublamellate. Tliev are often reduced in number, becoming confluent with each other at various distances from the posterior margin. Such a pattern of intercalations of concentric lirations was chosen by Bar- nard (1964a) as the best distinguishing trait in his synonvTn europisthus. RaniS,c. TcUiiui semen lives in offshore waters, usually in relatively coarse sub- strates from along the coast of east Africa as far south as Durban, through the East Indies and the Philippine Islands to as far east as the Fiji Islands. Smith (1903) first listed the species from Durban, and further documentation of range has been given by Lvnge (1909). Under the name
