coxa bears a tuft of long hairs with serrate edges. The joints 

 of the endopodite are unarmed, but bear fringes of ^etae. 



The cheUpeds are enormously developed, being very nearly 

 as long as the body, from rostrum to end of telson. They are 

 of equal size on each side. All the joints are more or less laterally 

 compressed. The two basal joints are very short. The ischium 

 is also short, and bears a row of four or five small teeth on its 

 lower margin. The merus is more than twice as long as the 

 ischium, and is strongly compressed. It is broader distally than 

 at the proximal end, and its inner or lower border bears fourteen 

 or fifteen teeth in a row, which is a continuation of thi t on the 

 ischium ; on the outer edge there is a faint crest. At the inner 

 distal angle there is an excavation allowing the carpus to 

 fold back close to the meiiis. The carpus is very short and 

 broad, and much thickened at its distal end, where it has a 

 tooth on the under side. The propodite is by far the largest 

 joint of the whole appendage. The hand is broad and massive, 

 and shorter than the finger, which is thin and tapering. Both 

 the fixed finger and the dactyl are straight for the greater part 

 of their length, and curve towards one another only near the 

 tip. In their proximal part they are furnished with large and 

 rather blunt teeth, whereas distally they have a row of small 

 denticules. The dactyl is slightly longer than the fixed finger. 

 The lower border of the propodite is very minutely serrate. 

 The inner margin of the whole appendage bears a fringe of 

 setae. The surface of the propodite is not smooth, but slightly 

 granular. 



The second pereiopods are very much shorter and more slender 

 than the chelipeds. They are strongly compressed, and bear 

 fringes of setae. The merus is the largest joint. The propodite 

 is very much flattened, and the dactyl can be folded back 

 against it, forming a subchela. The edge of the dactyl is sharp, 

 but has no teeth. 



The next two pairs of pereiopods end simply, but the fifth 

 are subchelate, like the second. The third are slightty longer 

 than the second, and also longer than the fourth, which in turn 

 are longer than the fifth. In the third pereiopods the lower 

 edge of the dactyl bears on its proximal half a row of ten or 

 twelve sharp curved spines, which are longest near the base 

 of the joint, and decrease in size distally. This row of spines 

 extends only half way along the dactyl, on the distal half of 

 which it is continued as a very close-set series of much smaller 

 spines extending to the tip. A similar arrangement may be 

 seen in the fourth pereiopods. 



Li the male the pleopods of the first segment are altogether 

 wanting ; in the female they are very slender and feeble. On 

 the next four segments they are well developed, with strong 

 basal joints, and two lanceolate blades fringed with pinnate 

 setae. Both outer and inner branches, of the uropods have a 

 transverse suture guarded by a row of teeth. The outer margin 

 of each branch has also three or four small teeth. There are two
