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 (SowerRsy, Pitspry). 
This species may easily be confounded with the young of Card. coronatum, Spgl., 
from which 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. Pitspry, however (loc. cit. p. 556), describes two varieties of C. Hunger- 
fordi, to which some of these characters cannot be applied.

West of Koh Chang, 20 fathoms, mud (2). 
Long. 11—12 mm. 
Distribution:— Salang, Mergui Isls., Andamans, Ceylon, Gulf of Manaar, 
Maldive Archip., Gulf of Oman, Aden, Red Sea, Seychelles, Amirantes, Mascarenes, 
Zanzibar, Cape of Good Hope (Jay). — Poulo Condor, Philippines, China Sea, 
“Coasts of Australia,’ Lifu, Viti Isls., Samoa Isls. 
As neither Sowerby nor Epa. Smiru 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 Epc. Smirx 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 haye examined,’ because 
already in 1878, in the “Proc. Zoo]. Soc. London,” p. 819, he had written concerning 
this same species “The Andaman examples are rather young and bear the remains
