Commonly distributed at Koh Chang, Koh Kut, Koh Kahdat and Koh Bidang, 

 3 — 30 fathoms, soft clay, sand and mud. 



Largest specimen: Long. 95 mm. 



Distribution: — Japan (Sowerby, Pilsbry). 



This species may easily be confounded ^vith the young of Card, coronatum, Spgl., 

 from ^vhich it is, however, distinguished by a stronger gloss, the absence of ribs 

 at the middle, and by its often being ornamented with two reddish-brown tints 

 at the middle on each side of the umbones (young specimens of C. coronatum 

 have often reddish-brown wavy lines transversely across the valves), the valves 

 are more tumid, and the posterior side somewhat prolonged in a rostrum-like 

 manner. Pilsbry, however (loc. cit. p. 556), describes two varieties of C. Hunger- 

 fordi, to which some of these characters cannot be applied.

Long. 11 — 12 mm. 



Distribution:— Salang, Mergui Isis., Andamans, Ceylon, Gulf of Manaar,

As neither Sowerby nor Edg. Smith mention Card. Australe, Sow., in their lists 

 of the Mollusca of South Africa I think that Jay's record of the occurrence of the 

 species at the "Cape of Good Hope" should be regarded as open to doubt. It is a 

 mistake when Edg. Smith in his report on the Lamellibranchiata of the Challenger 

 Expedition writes regarding this species that "it is not apparently adorned with an 

 epidermis, judging from the series of specimens which I have examined," because 

 already in 1878, in the "Proc. Zool. Soc. London," p. 819, he had written concerning 

 this same species "The Andaman examples are rather young and bear the remains
