SUPPLEMENTARY DESCRIPTION OF CALLIANASSA

Callianassa (Callichirus) tridentata VON MARTENS, reported for the first time from the coast of Java about a century ago, was recently collected by Dr. Torben WoLFF of the Universitetes Zoologiske Museum, Denmark during the Noona Dan Expedition to New Britain, the Bismarck Archipelago in 1962. The morphology of this species has not yet been fully described. VoN MARTENS ( 1868) originally reported this species, however, his description does not always fix the species as DE MAN (1928a, p. 27) pointed out that "the original description, without figures, appears insufficient for well recognizing it. " CouTIERE ( 1899) examined the type specimen, but he was unable to refer to the carpus and chela of the larger cheliped, because these segments were wanting on the specimen. Follow-ing him, DE MAN ( l928a) examined the type specimen again and gave a good ref-erence to this species, though he could not make a close observation of the same parts of the larger cheliped either. For the above-mentioned reason, the present author is going to give here the supplementary description of this species basing on the four specimens, one of which was collected from New Britain and the others from Ceylon
