the upper with shorter pedunc4e, also the mandibular palp has 

 not the penultimate joint so widely expanded. 



Body with short setae thinly scattered over the surface. First 

 four pairs of side-plates considerably deeper than their respective 

 segments, evenly rounded below and unclothed, the first not in 

 the least expanded distally ; the fourth slightly deeper than wide. 

 Last pair of epimeral plates of metasome with posterior angle 

 minutely angularly produced, margin above entire and a little 

 convex, ventral margin almost straight and unarmed, anterior 

 angle narrowly rounded. 



Cephalon equalling in length the first two segments of meso- 

 some combined. Eyes circular, black. 



Upper antennae less than half the length of the body, with few 

 setae ; peduncle short, nob longer than the cephalon and half of 

 the first joint of mesosome combined, its ultimate joint rather 

 more than half the length of the penultimate ; flagellum consider- 

 ably longer than twice the length of peduncle, with 40-50 short 

 articuli, secondary appendage, normal, one-jointed. Lower 

 antennae of about equal length to the upper, with few setae ; 

 peduncle extending to the limit of upper, flagellum more than 

 twice the length of peduncle with 30-40 joints. 



Gnathopoda subequal, the second with the basal joint a little 

 longer than the first, hands small, not any larger than the first, 

 and of identical form, carpus equal in length to the propodus, 

 lobed posteriorly and thickly clothed with long spineforni setae ; 

 propodus oblong, subquadrate, palm oblique, very slightly con- 

 cave, fringed with a few spinules, and at the limit a row of four 

 or five stout spines ; forming with the hind margin a right-angle ; 

 hind margin broken by two or three transverse ridges of long 

 spineform setae, the distal one being the most prominent, 

 anterior margin with four fascicles of setae, and on the outer face 

 a single bunch near the palm. Dactylus as long as the palm, 

 inner margin with about four equidistant fine spines, and on the 

 outer margin a faintly pectinated one a little more proximally 

 than the middle length. 



First two pairs of pereiopoda much longer than the gnatho- 

 poda, of equal length and form ; last three pairs quite similar 

 in form to each other, gradually increasing in length distally ;
