than the lamellar portion which is distally truncated, it pro- 

 jects beyond the antennular peduncle. The peduncle reaches 

 more than half the length of the scale, the flagellum is slen- 

 der and long. 



The third maxillipeds are similar to those of the preced- 

 ing species, reaching forward nearly as far as the upper flag- 

 ellum of the antennule. 



The first pair of legs are strong, with the chelate limb on 

 the right side, in this the merus is longer than the carpus and 

 propodus together, the carpus is short, the palm a little longer 

 than the carpus, the fingers are short.er than the palm, they are 

 acute and simple. On the opposite limb the propodus tapers 

 much, and is slightly longer than that of the right side, and 

 slightly setose, the dactylus is short, sharp, and curved. 



The second legs are very slender, the ischium joints are 

 considerably more expanded than in the preceding species, that 

 of the right side has the ischium and merus subequal in 

 length, the carpus being as long as these two together, very 

 mobile, and composed of about 40 articuli, which do not ex- 

 pand towards the distal end : the limb ends in very minute 

 chelae. The limb of the left side is shorter and has the 

 carpal joint with about 20 articuli, which become gradually 

 more expanded distally, the propodus and chelae being well 

 developed. In these limbs the meri have very obscure annula- 

 tions. 



The three pairs of ambulatory legs are long and slender, 

 with — except- in the last pair — the carpi slightly longer than 

 the propodi, the propodi have on their anterior margins a 

 close row of very minute and regular hairs, the posterior mar- 

 gins are setose in scattered fascicles. The dactyli are short, 

 simple, and have one or two small fascicles of hairs near the 

 terminal claw, which is minute. The ischii and meri of the 

 two first pairs of these legs are obscurely spined, as in the pre- 

 ceding species. 



The pleopods are robust. 



The telson is narrow, long, tapering to a narrow end, and 

 on its dorsal surface minutely aod sparingly pubescent, the 

 quadrately placed spines are obsolete or nearly so — the ter- 

 minal spines are broken off in this specimen. 



The uropods are about as long as the telson, the outer 

 ramus has its external margin straight, terminating in two 

 small spines : the division, which is well marked, is somewhat 

 arched. 



Length of body, excluding rostrum and telson, 18 mm. 

 ,, ,, carapace, 6 mm.
