In the external maxillipeds the dorsal and ventral borders of the ischium 

 end each in a spine, and there are two very strong spines on the ventral border 

 of the merus, while the dorsal border of the same joint ends in a small spine.

Differs from M. trifida only in the following particulars : 

 The appendages are much less pilose and the body is almost devoid of 

 tomentum : the rostrum is a good deal more than half the length of the carapace : 

 there is a large spine on the cardiac region : the front edges of the second to 

 fourth abdominal terga are armed in the middle line, the second with a large 

 hook-shaped spine,* the third and fourth with a pair of spines : the chelipeds are 

 much less spiny, the hand being quite smooth, and the carpus having only a pair 

 of distal spines : the carpopodites of the second to fourth legs have only a single 

 spine, terminal in position, on the front border. 



There is an epipodite on the chelipeds as large as that of the external 

 maxillipeds. 



Length of fully extended body of female 23 millim. ; of chelipeds 19'5 millim.

The entire dorsal surface both of body and of appendages is covered with 

 a remarkably thick velvety down. Bpipodites, Avhich are as large as those of 

 the external maxillipeds, are present on the chelipeds. 



The rostrum, which is half the length of the carapace proper, is moderately 

 broad, convex, carinated, and armed in its anterior half with a single pair of 

 strong divergent spines. 



The carapace is semi-elliptical, and strongly convex, and is traversed fore 

 i aft in the middle line by a raised row of coarse granules or spinules, of which
