LARVAE OF DECAPOD CRUSTACEA 383 Stage I, and his second larva represents stage III, in which the uropods appear. The development of Stenopus thus conforms to the normal sequence with the exception of the early appearance of leg i. The next known stage attributed to S. hispidiis (Gurney, 1924, p. 136) is probably stage V, and has a total length of 14-8 mm. (rostrum 4 mm.). This stage is that shown in Fig. 2.

The first three pairs of legs are developed, with setigerous exopods, but with very small endopods, borne low down on the basis. Legs 4 and 5 are minute uniramous rudiments. Pleopods absent, but uropods large, with numerous Fig. 2. Stenopus hispidus (Olivier), 15 mm. St. 705 Stage VI?. Length 17-18-6 mm. This stage differs only in the appearance of pleopods and the greater development of limbs. Beyond this size it is probably impossible to define stages, as it appears that develop- ment goes on for a long time with increase of size but very little change in structure. The largest specimens seen were taken by the 'Atlantis'. Stage (Fig. 30-^). Length: rostrum 8-8 mm.; thorax 5-0 mm.; abdomen 17-5 mm.: total 31-5 mm. General form of body and spines the same. Telson long and narrow, with a pair of terminal spines and setae between. Antennule, peduncle of three segments; rami about three times as long as segment 3. Antenna, endopod longer than scale, without setae. Mouth-parts very little changed. Maxillipede i with very large epipod; exopod with eight setae; endopod of three segments. Maxillipede 2 with epipod; exopod with.
