segment. The second segment, measured dorsally, is shorter than 

 the third. The accessory antennular ramus is shorter than the 

 peduncle and is fused with its fellow for a length considerably less 

 than that of the last peduncular segment, the fused portion con- 

 sisting only of some 5 or 6 segments. 



The antennal scale is broadly rounded apically, the lamella 

 extending much beyond the spine that terminates the straight 

 external margin. It is about three times as long as wide. 



The mandibular palp is composed of three segments, the third 

 nearly twice the length of the second. The third maxillipedes 

 reach to the end of the antennal peduncle ; the terminal segment 

 is about two thirds the length of that which precedes it. 



The first peraeopods reach the end of the antennular peduncle. 

 The carpus is about one fifth longer than the merus and is a little 

 more than twice the length of the chela ; the fingers are longer 

 than the palm. 



The second peraeopods may reach beyond the tip of the an- 

 tennal scale by nearly the whole length of the chela. The ischium 

 is equal to or a little shorter than the merus and the carpus is 

 between i^ and li times as long as the ischium. The chela is about 

 equal to (sometimes a trifle shorter than, sometimes a trifle longer 

 than) the carpus; the palm is not swollen as in the preceding 

 species and is from one fifth to one tenth shorter than the fingers. 

 The latter are straight with short, inturned corneous tips and 

 are without teeth on the inner margin. 



The last three pairs of peraeopods are slender; the third pair 

 is the shortest, not quite reaching the end of the antennal scale; 

 the fourth and fifth pairs are longer, extending beyond the scale 

 by a portion of the length of the dactylus. In the third pair the 

 propodus is less than twice the length of the carpus and is about 

 one and a third times the length of the dactylus. In the fourth 

 pair the propodus is longer, from two to two and a quarter times 

 the length of the carpus, the dactylus being longer than the latter 

 segment. In the fifth pair the dactylus is longer than the carpus 

 and the carpus is about three sevenths the length of the propodus. 

 The propodus of all three pairs is provided with a bunch of setae 

 at its distal end and, in the case of the fifth pair, is thickly set 

 with short hairs on the distal half of its inferior margin. The 

 dactylus in each pair is without teeth, slightly curved, with some 

 long setae on its upper border. 



The abdomen is compre.ssed but not carinate above. The 

 sixth somite, measured dorsally, is rather more than half the 

 length of the carapace. The pleopods are short, those of the first 

 pair being shorter than the carapace. 



The telson reaches to rather more than two thirds the length 

 of the outer uropod. It bears two pairs of dorsal spinules dis- 

 tally ; the apex is produced to a sharp point with two plumose 

 setae beneath and two spinules on either side, the inner pair of 

 the latter extending considerably beyond the tip. The outer 

 uropod is about three times as long as broad. There is a movable
