Sjicri/ii- Chnrnrtri-*. l-"<'nmi< . liody very robust, with the back more or 

 less curved, and the segments of the anterior division sub-imbricate dorsally. 

 i 'ephalic ^cgment of very large si/e. and conspicuously compressed in its an- 

 terior part, the epimeral parts being very deep and arcuate. Rostral projection 

 short and blunt at the tip. JJrosome scarcely exceeding half the length of the 

 anterior division, and having the segments very sharply defined; genital segment 

 large and broad, seen dorsally, quadrangular in form, with the lateral parts lamel- 

 larly expanded; last segment very small, often almost wholly concealed by the 

 preceding segment. Caudal rami comparatively short, not much longer than they 

 are broad, and transversely truncated at the tip. each with a short seta at about 

 the middle of the outer edge, innermost but one of the apical setne much coarser 

 than the others, and about equal in length to the urosome. Eye large and very 

 conspicuous in living specimens. Anterior antennae scarcely exceeding half the 

 length of the cephalic segment, 2nd joint much the largest, about equal in length 

 to the -2 succeeding joints combined, terminal part of about the same length. 

 Anterior maxillipeds less compact than in the other species, with the claw of the 

 outermost lateral lobe smaller, terminal part distinctly developed, narrow cylin- 

 drical and inarticulate. Posterior maxillipeds exceedingly large and powerful, with 

 the hand considerably dilated, and forming a prominent angular projection below, 

 defining the palm in front, the latter deeply concaved in the middle, with the edge 

 densely spinulose throughout; terminal claw very strong and provided at the ba-e 

 inside with a slender spine. First pair of legs with both rami of equal length, 

 the outer one somewhat narrower than the inner, and angularly bent near the 

 ha^e. each ramu> armed at the tip with '2 unequal claws finely denticulate along 

 the eoncase edge, and accompanied inside by a small, hair-like bristle: terminal 

 joint of outer ramiis. moreover, exhibiting on the outer ed^e -2 minute spinules. 

 L.-i>t pair of legs exceedingly large, extending beyond the limits of the genital 

 -eminent: distal joint oblong oval in form, and evenly rounded at the tip: inner 

 expansion of proximal joint extending as far as the distal one. and somewhat 

 narrowed in its outer part: marginal seta 1 of both joints comparatively short 

 and Dimple. 



Mulr >ome\shat smaller than female, and easily recognised by the more 

 strongly built and geniculate anterior antennae and the distinctly ">-articulate uro- 

 Inner ramii^ of _?nd pair of legs transformed in the usual manner. Last
