biting portion quadrate and bearing on its free margin a series 

 of curved unguiform processes ; the remaining three lobes are 

 digitiform and bear long plumose setse. The first maxilliped 

 has a wide basis, from which spring four short setiferous lobes. 

 Second maxilliped prehensile, composed of two elongated joints, 

 the last bearing a very long and slender apical unguis, which 

 is provided on its concave margin with six very slender but 

 comparatively long setse. First and second pairs of thoracic 

 feet alike in both sexes. The protopodite of the first pair 

 is very large and wide, two-jointed, and bears numerous mar- 

 ginal setse : inner branch two-jointed, the first joint about 

 thrice as long as broad, the second not half as long as the first 

 and bearing a very long apical unguis, which is swollen at 

 the base and very sharply curved at the extremity ; both joints 

 bear several strong setse on their inner and outer margins; the 

 outer branch consists of two short, broad, and nearly equal 

 quadrate joints, and is not much more than hsilf as long as the 

 first joint of the inner branch : its first joint bears a long spine 

 on the outer margin, as well as one or two smaller setse, the 

 second also has a marginal spine, and on its truncated apex three 

 similar spines and one rather long and slender seta ; the inner- 

 most of the three apical spines is plumose. Inner branch of the 

 second foot two-jointed, about as long as the first two joints of 

 the outer branch, but much more slender, the two joints nearly 

 equal in length, setiferous on both margins, the last joint bear- 

 ing at its apex two long and equal setse ; outer branch stout, 

 three- jointed, each joint bearing a fascicle of about three stout 

 setse on its inner margin; the outer margin of each joint pro- 

 vided with a long and stout spine as well as a few short setae, 

 those of the first joint being numerous and closely set ; apex of 

 the last joint truncated and armed with three strong spines. 

 The third pair of feet in the female are almost like the second, 

 but in the male are much stouter and more strongly spined, 

 while the second joint of the inner branch has its margin pro- 

 longed into a large spinous process which reaches beyond the 

 apex of the joint, and by its very wide base seems to divide the 

 joint into two. Fourth pair of feet rather shorter, alike in both
