First peraoon sogment nearly as long as the cephalon ; second 

 and third equal ; fourth a little longer than the third. 



Eyes rather large, but not prominent; colour l)lackish-bro\vn. 

 First antennte with the basal joint short and stout ; .second 

 joint more than three times as long as broad ; third twice as long 

 as broad ; foui-th equal to the two preceding joints combined. 



The first joint of the second antennae is stout, 

 and about 0*5 mm. in length ; there arc two 

 small spines on the upper boi'der ; second joint 

 1 nmi. long ; the superior border carries six 

 spines, three on each side of the median line ; 

 they are unequal in size, but at regular distances 

 apart ; third joint 3 mm. long, fourth 3"5 mm., 

 fifth 1-2 mm., and the sixth 0*25 mm. ; the 

 distal extremities of the third and fourth joints 

 are somewhat swollen. 



Mandibles stout, straight, with a tridentate 

 cutting edge, and a rather broad spine row ; 

 molar tubercle prominent, with an oblique 

 apex. 



Maxillipedes short ; the epipod is rather large 

 and broadly lanceolate ; first and second joints 

 of palp equal, and about as long as broad ; 

 third joint twice as long as broad ; fourth joint 

 one-third longer than broad ; the length of the fifth equals the 

 diameter of the fourth. 



In the first pair of legs the third joint 

 is nearly as long as the two following com- 

 bined ; sixth joint equal to the second, and 

 nearly twice as long as the seventh. 



Second joint of the second pair of legs 

 four times longer than broad, with three 

 spines on the superior border ; third joint 

 about twice as long as broad ; the apical 

 third is swollen, and there is a single spine 

 on the superior border near the extremity ; 

 the fourth joint is one-third shorter than the 

 second ; it gradually increases in diameter 

 distally, and terminates superiorly in a large 

 projecting spine ; fifth joint four times as 

 long as the third, with one or two spines on 

 the proximal half of the upper border ; sixth 

 joint a little shorter than the fifth ; seventh 

 very short, scarcely equal to the diameter of 

 the preceding joint. 



The third and fourth pairs of legs differ
