抄録: Two berried females of the spiny lobster, Pamulirus polyphagus (Herbst) were caught with trawl net operated by the T.S. Nagasaki Maru of Nagasaki University at the fishing ground (Lat. 2° 35.4' N, Long. 109° 57.0' E) of sandy mud bottom in the South China Sea off Kuching, Borneo (Fig.1, Table 1). The spiny lobsters caught on August 30, 1971 were kept in an aquarium provided with a running water system on the ship, fed with fish meat, and transported to Nagasaki (Lat. 32°40, 5'N, Long. 129°50. 5'E), Japan. After the arrival in Nagasaki on September 16, 1971, the spiny lobsters were landed and reared in a concrete tank of the Fisheries Experimental Station of Nagasaki University situated in Nomozaki near Nagasaki. Numerous individuals of the phyllosoma were hatched out from the berried lobsters in the nights of September 16 and 18, 1971. After the larva hatchings, the parent lobsters were fed mainly with the clam, Tafes (Amygdala) philippinarum and reared until next March. During the rearing period the water temperature of the concrete tank descended from 25℃ to 10.5℃. One of the parent lobsters (Spec. No.1 in Table 1) again produced eggs on October 6, 1971 at the water temperature of about 22℃, but the eggs dropped off from the parent lobster by the 20th of the month. Another parent lobster (Spec. No.2) molted on December 8, 1971 at the temperature of 14.5℃, but the growth of the lobster was not induced by the ecdysis.The rearing experiment of the phyllosoma hatched out from the lobsters was carried out but in vain. The first phyllosoma of the present spiny lobster (Spec. No.1) ranges 1.43 to 1.46mm in body length and it is the same in both form and size as the phyllosoma hatched out from the same lobsters of Penang, Malaya and Bombay, India which was already described by Ong (1967) and Deshmukh (1968) respectivelly, except that the present phyllosoma has minute teeth on the stems of the first and second antennas, while the phyllosoma of Bombay has very smooth antenna stems (Table 2, Fig.2). And also the present phyllosoma is the same as that of the Japanese common spiny lobster, Panulirus japonicus (Von Siebold), but the former having a sub-expedial spine on every periopod differs from the latter having no sub-expedial spine (Fig.3).
