loped, several of them strongly pectinate; the coupling spine 

 is rather near the end. The lobes of the palp are long. 



The legs are of the usual type, and spiniform. 



In the first and second pleopods the exopods are areo- 

 late, or apparently covered with scale-like markings. The 

 appendix masculina is thick and concave, or semi-cylindrical 

 for its whole length. The exopods of pleopods three, four, 

 and five have divisions; that of the fifth has two lobes on 

 the distal end, and two at the inner side on the angle of 

 the proximal division. 



The uropods have a short inner ramus, the end of which is 

 subacute, and projects backwards, it does not nearly reach 

 the notch. The external ramus is long, cylindrical, curved, 

 and ends in a recurved hook, with two or more less curved. 



In a female, whose mouth parts are modified in the 

 usual way, the size is the same as that of the male ; the more 

 posterior segments of the thorax are very short. The pos- 

 terior notch of the pleon is roofed over by a process which 

 projects far behind, and is turned up at the end and bifid. 

 The uropods are weaker than in the male, the inner rami 

 more acute, the outer more hooked. 



In an unmodified female which I have figured the ex- 

 ternal rami of the uropods are very strongly hooked, there 

 being three other curved spines on each. The inner ramus 

 is very acute. The legs are rather slenderer than in the 

 male. 



In both sexes the limbs are dotted with black spots.

The body is strongly convex, smooth, with areolate 

 markings ; glabrous, with one or two lateral tubercles on each 

 side of the sixth and seventh segments of the thorax. 

 Obscure tubercles are also indicated on the posterior margins 

 of more of the segments in some males. 



The head is evenly rounded anteriorly, the margin being 

 slightly thickened; it is narrower than the first segment of 

 the thorax, and more than twice as long. The rostral por- 

 tion is broad and distally truncated, meeting the anterior 

 part of the epistome by a transverse sutural line. 



The segments of the thorax are short, and do not differ 

 much in length. The epimera are nearly vertical in direc- 

 tion, somewhat sculptured, and at their junctions, with their 

 respective segments, are raised, forming an interrupted 

 longitudinal ridge, which also is marked on the first seg-
