The Proboscis is of moderate length, 2mm., measured dorsally, cylindrical but 
slightly swollen in the middle; it is directed downwards, and not setose at all. 
The Chelifori are well developed ; the scape is single-jointed, stout, and scarcely as 
long as the proboscis. A row of stout spines runs along its inner border, and a few 
spinous setse constitute a distal fringe, and there are two or three scattered on the 
shaft. The chela is strong, the palm taking up half its length, and the fingers are 
set at a considerable angle. The palm is covered, but not thickly, with setse. The 
fingers are slender, curved towards the tip, and provided with slender teeth of fairly 
uniform length, but not very closely set. 
The Palp rises laterally, quite close to the proboscis, and consists of the normal 
five joints (fig. 3a). The first is short and stout, the second is the longest of the 
appendage and provided with a few long setse; its proportion to the remainder is 
9 : 5’5 : 1'5 : 1‘6 ; the third is scantily supplied with setse, the two terminal joints are 
rather more abundantly supplied ; the last joint is ovoid instead of cylindrical. 
The Ovigers arise ventro-laterally immediately in front of the first pair of lateral 
processes. They comprise ten joints of normal character (fig. 3b). The first three 
joints are quite short, stout, and progressively lengthening ; the proportions of the three 
following are 7:9:5. Setse become prominent, but not numerous, on the fifth and sixth 
joints ; on the preceding joints they are almost non-existent. The four terminal joints 
are small, the proportions being about 4‘5 : 3 : 2‘5 : 2'75, the last one possessing a 
curved terminal claw, quite as long as the joint, with half-a-dozen rather widely 
separated teeth. All the terminal joints carry a few setse distally and dorsally. The 
denticulate spines are not numerous, 5 : 4 : 3 : 4 respectively ; they consist of the normal 
flattened blade with two prominent teeth on each side, and two others of which traces 
remain. They are rather worn. (Plate X., fig 13.) 
The Legs are rather short, about 16mm., very stout, but the tarsus and propodus 
are very much reduced in diameter. Of the three coxse the second is much the longest, 
but not so long as the other two together. The first is provided clorso-laterally with 
two stout spines, and there is another rather smaller one laterally, on the posterior 
side. A row of spinous setse occur laterally on the other two coxse. The distal 
fringes of these two joints are ventral and inconspicuous ; that of the third coxa 
is the best developed, and on this joint there are several small setse ventrally in 
addition. The three following joints are subequal in size, the tarsus and propodus 
together are three-quarters the length of the preceding joint, and are themselves sub¬ 
equal. In these particulars this species is not in agreement with the preceding. On 
the two tibiae there are two dorsal rows of stout spinous setse, a lateral row on either 
side, and a strongly developed ventral row. On the second tibia the distal fringe 
is strongly developed ventrally, and spinous. The setse on the femur are smaller, 
and only the two dorsal rows are distinct; the other three rows are present, but 
very feebly developed; there is a prominent distal fringe dorsally. The tarsus and 
propodus are similarly provided, but the setse are much smaller. The terminal claw
