process (fig. 2a). The first joint is small and stout, the second is more than twice 
as long, stout and enlarged distally, the third is scarcely as long and has an oblique 
termination. These three joints form a curve in one direction, and the three following 
form a similar curve in another. The fourth and fifth joints are long and subequal, 
the sixth being about half the length of either ; its termination is rounded, the 
following joint being articulated at the side. All these joints are more or less 
plentifully setose; the setae are very small, but their structure and arrangement call 
for no comment. The seventh and succeeding joints progressively decrease in length 
and stoutness as far as can be made out from the angle at which they lie, and they 
are all small. The seventh lies at right angles to the sixth, and near its distal and 
inner side it bears a dense tuft of long setae. The eighth joint is articulated at 
the side of the seventh and at right angles to it; it also bears a small tuft of long 
setae near its distal extremity but on its outer side; the following joint is similarly 
provided, but with fewer. The last three joints bear an irregular series, not a single 
row, of stout spines (fig. 2c); most of them occur on the terminal joint, but there are 
scarcely a dozen altogether. There is no terminal claw. 
The Oviger of the female is essentially different to this (fig. 2b). All the joints 
are smaller, the third conspicuously smaller than the preceding, and the fourth, though 
the longest of the appendage, is still quite short, and the remainder gradually and 
progressively decrease in length. Up to the sixth the joints remain stout, the rest are 
much more slender, and there is nothing noteworthy in their articulation, which is 
quite normal. The sixth joint is thickly covered on its outer side with minute setae, 
and up to this joint the setae have been increasing in number. The terminal joint is 
unfortunately missing in the specimen examined, but the three preceding are almost 
devoid of any setae at all. 
The Legs measure about 28 mm. in length. The second coxa is scarcely the length 
of the other two together, the femur measures some 7 mm., the first tibia is the merest 
trifle shorter, the second a little longer, 7'5 mm., the tarsus and propodus together are 
about one-third the length of the second tibia. The second coxa bears a small but 
distinct tubercular enlargement just beyond the middle of its length dorsally, and in 
the male there is a similar tubercle dorsally near the extremity of the femur, with 
a glandular aperture upon it. The entire limb is setose, but the setae are very small; 
no definite arrangement can be seen as far as the first tibia, up to this joint they are 
not numerous and only visible with difficulty. On the tibiae they become numerous ; ou 
the first their arrangement is indistinct, on the second it is more readily made out, and 
consists of a dorsal and a ventral band of setae with another narrow band passing along 
the centre of a bare space laterally. The distal fringes are but poorly developed, the 
most conspicuous one being on the second tibia and chiefly ventral. The tarsus is a 
very small cuplike joint, densely setose on its longer and ventral margin. The propodus 
is slightly curved and dorsally projects considerably beyond the insertion of the large 
terminal claw and its strong auxiliaries. The joint is thickly covered with stout
