Spines on all the joints of the antennae, except the last minute one of the flagelluai, 

 which ends in a microscopic brush. 



Upper lip with the hirsute lower edge (apparently) minutely emarginate. 



Eight mandible with six teeth on the cutting-edge, of which two are prominent; 

 the inner plate with four teeth ; spine-row consisting of five plumose bristles ; molar 

 tubercle with oval grinding-surface of more than twenty rows of denticles, with a 

 brush of hairs at either end. Left mandible similar, but inner plate shorter, less 

 flat; four bristles to the spine-row, which together with the biting-plates is more 

 remote from the molar tubercle than in the right mandible. 



Lower lip with broad lobes, well furred along the distal and inner margins, the 

 mandibular springs short. On the inner side, standing clear of the lobes, is a narrow 

 plate less than half the length of the lobes, narrowing almost to the distal end, which 

 is minutely emarginate. 



First maxillae : outer plate oblong, crowned with ten spines, mostly pectinate in the 

 distal half. A slight interruption in the outer margin indicates the position of a 

 rudimentary palp. The inner plate bears distally two plumose bristles. 



Second maxillae: plates about equal in breadth, the outer projecting beyond the 

 inner, distal edges armed with slightly curved spines, neither long nor stout ; on the 

 inner plate the series is continued some way down the inner margin, concluding with a 

 plumose bristle longer than the preceding spines. A spine also occurs on the inner 

 surface of this plate, nearer to the distal end than the bristle just mentioned. 



Maxillipeds: inner plates long, with three teeth, some spines at the distal end of 

 each; outer plates short, scarcely extending beyond first joint of palp, round the distal 

 end and nearly halfway down the inner margin bushily fringed with short spines, the 

 remainder of the margin naked ; a group of five short spines on the external surface, 

 just below the inner basal angle of the palp. The palp 3-jointed, the joints short, 

 subequal in length, the second lobed distally on the inner side ; the second and third 

 fringed bushily on the inner side with short spines, which may or may not conceal a 

 rudiment of a fourth joint. 



First gnathopods : side-plate almost concealed by that of the next segment, the front 

 margin a little concave towards the upper half, the lower margin projecting in front, 

 spined. The first (free) joint with stift' spines on all three margins, and a few dispersed 

 on the surfaces. The fourth joint is more than three quarters as long as the first; it 

 has a small, nasiform, microscopically furred lobe near the hinder distal end, within 

 which is a long spine constricted near the middle, and then pectinate on both edges. 

 The hand is shorter, narrower, an oblong slightly curved, with a hinder distal, squarish, 

 minutely furred lobe, beyond which the point of the finger projects. Both wrist and 

 hand are armed on both edges, distal margins, and both surfaces, but especially the 

 inner, with numerous spines of various lengths. The second and third joints are also
