converging backward. External maxillipeds (fig. 2«) nearly closing- the cavity, ischium longer 

 and broader than merus, the latter with the antero-external angle smoothly rounded, but 



sowewhat produced outward. 



Chelipeds somewhat unequal (the right chela being the larger), as long as, but much 

 strono-er than the walking legs, mostly covered with the same fur of closely-set, club-shaped 

 hairs as are observed on the carapace. Meropodite short, inner and upper margin sharp, the 

 former with a series of long hairs, terminating distally into a prominent tooth; outer surface 

 thickly hairy, with a prominent, transverse ridge near the distal end. Carpopodite bulky, upper 

 surface tuberculate or granulate, but the sculpture is concealed mostly beneath the fur; in the 

 middle of the surface we observe a roughly quadrangular space of a callose 

 appearance, entirely devoid of hairs and somewhat raised above the sur- 

 roundings; the inner angle of the wrist is somewhat produced and an exactly similar 

 tooth is found on the opposite margin of the wrist. Chela strong, palm twice as 

 long as the fingers and longer than high, both margins rounded, but inferior margin slightly 

 keeled and somewhat sinuous where it passes into that of the fi.xed finger; outer surface in the 

 larger (right) chela smooth for the greater part, though with reticulating, interwoven, ivory-white 

 lines on a darker ground-color, which lines are divided into groups by three or four similar, 

 but longitudinal lines; near upper border the surface is closely covered with the usual fur and 

 a series of ordinary hairs runs along this border and extends to the back of the movable finger, 

 only partly concealed by the fur numerous large, pearly granules are to 

 be seen on the palm; in the smaller chela similar granules, arranged in longitudinal rows, 

 are found all over the outer surface, in the middle of the latter only they are not covered 

 with hairs, and the fingers, especially in the gap between them and at the inner sides, are 

 much more hairy; the fingers are slightly compressed and have retained a greyish hue over 

 their greater part, the inner margins are crenulate, the teeth gradually diminishing in size from 

 base to tip of finger. 



Walking legs not very long, the penultimate pair measuring about i^j„ times the length 

 of the carapace, frmged with club-like" hairs. Meropodites six times as long as broad, anterior 

 margin wavy, each prominence capped by a cluster of thick and short hairs; 

 on each leg there are six to eight of such prominences, increasing in height distally, but in 

 the last pair the margin is continually fringed with hairs, and only one subdistal prominence is 

 to be found. Propodites flattened, fringed along both margins. Dactyli very long, not flattened, 

 nearly straight, slightly longer than propodites, fringed with feathered hairs of different length; 

 in the last pair they are not curved at all, longer than the preceding joints and the hairs 

 are longer. 



Base of abdomen of cf (fig. 2d) completely occupying the space between the last legs, 

 second segment considerably narrower, but widening distally, third segment greatly produced 

 laterally, as wide as the first, but not reaching coxopodites of posterior legs; parting from this 

 segment the abdomen narrows considerably, but the lateral margins of the penultimate segment 

 are perfectly parallel, the last segment is semi-elliptical. 



This species offers so many characteristiq features, that it may be easily recognized. It
