抄録

During his journey from March to June of 1976, Dr. Tetsushi Senta, the head of the Fisheries Experiment Station attached to the Faculty of Fisheries, Nagasaki University, investigated the milkfish of the Philippine Islands. While in N. W. Luzon Island he saw by chance an edible fresh-water prawn from Paoay Lake, boiled plain in a restaurant at the town of Batac; then he visited the Lake near the town and obtained one of that type of prawn from a fisherman. According to Dr, Senta it is caught in a small fish trap composed of a split bamboo fence, placed in the shallow waters (about 1m. deep) on the Lake at night. As the result of the present writer's examination of the said collection (5♂♂, 2♀♀), the formulae of the rostrum teeth (Table 1) and the character of fingers of the second hand (Text-fig. 4, C) of the adult male who's body length is 58mm., agree well with Dana's original description and Cowles' detailed observation of Palaemon lanceifrons (=Macrobrachium lanceifrons lanceifrons) from the neighbourhood of Manila. The teeth of rostrum range along its whole upper margin at varied intervals. The second hand is not slender than the carpus. The eggs borne by 43mm. long mother prawn are subglobular in shape, and about 0.95mm. long and 0.85mm. broad, which is a little larger in size than that used in Cowles' data.
