In November, 1964, the research vessel Cape St. Mary of the Fisheries Research Station, Hong Kong, made her seventh cruise of the year to the coast of Sarawak, Borneo. During this cruise, a series of AGASSIZ trawl-hauls were taken from deep waters. At Station 32, which was about 270 miles north of Kuching, Sarawak, 19 fish species were collected from depths of 456 to 450 fathoms. Among these fishes, a new skate of the genus
Anacanthobatis has been identified. The following account of this skate is the first record of
Anacanthobatis, as well as the second record of the Anacanthobatidae, from the South China Sea.
According to BIGELOW and SCHRODER (1962),
Anacanthobatis is distinguished from
Springeria, the other genus of the family, by the absence of the leaf-like expansion at the tip of the snout. It is known only by three species:
A. marmoratus VON BONDE and SWART, 1924, from Durban, Natal, and
A. americanus and
A. longirostris, both of BIGELOW and SCHROEDER, 1962, from the Gulf of Mexico. The present new species from the South China Sea is, therefore, the fourth species of the genus, which can readily be distinguished from the known forms by the following simple key.
