PYCNOGONIDA. 13 
The Legs are long, attaining a length of 69mm. The lateral line is conspicuous, 
beginning on the lateral processes and extending to the end of the second tibia. Of 
the three coxze the second is longer than the other two together, all three are thickly 
covered with small spinous sete on the ventral surface, but, except on the first coxa, 
there are none dorsally. The proportions of the three following joints are as 17 : 14°5 : 21. 
The femur is fairly well covered with minute set ventrally; dorsally they are much 
less numerous, except at the distal extremity. A linear arrangement of the sete is 
observable, but it is not very regular, a distal fringe is not very prominent, and almost 
confined to the dorsal side. On the first tibia the setee become more numerous dorsally, 
they preserve the same general arrangement, but there are longer setee mixed with them. 
On the second tibia this becomes much more pronounced, and ventrally the sets are so 
numerous that the linear arrangement is completely obscured ; the distal fringe on both 
joints is well developed, more especially so on the ventral side of the second tibia. The 
tarsus is very small, the ventral surface being double that of the dorsal; the former is 
covered with long spinous sete, most prominent distally, like those of the distal fringe 
of the preceding joint, dorsally they are smaller, but form a well-developed fringe. The 
propodus is slightly curved, and completely covered with small spinous setee, and some 
of these form a distal fringe over the insertion of the terminal claw and its auxiliaries. 
At the proximal end of the joint is a series of some half-dozen short spines, the centre 
ones being the largest ; beyond these a group of stout spinous setee extends to the end 
of the joint. The terminal claw is short, half the length of the propodus, and the 
auxiliaries are about half its size. 
Of the two specimens obtained one is a male, and the Genital apertures occur on 
a slight swelling at the distal extremity of the second coxee of the two posterior pairs of 
legs. On the ventral surface of the femur is a swelling about the middle of its length, 
and this bears a short but stout duct characteristic of the males of this genus. The 
Genital apertures of the female occur on a very pronounced swelling, in a similar 
position to those of the male, but on all the legs. 
This specimen is remarkable for having the first leg of the right side complete in 
all essential details, but not extending beyond the distal extremity of the femur of the 
normal limb. 
Winter Quarters, off Flagon Point. January 17th, 1903. 5-20 fm. Very 
rough ground. 
PALLENOPSIS VILLOSA. 
(Plate II., fig. 1.) 
Body robust, with lateral processes rather close together. Entire animal clothed with long, 
slender sete, giving it a woolly appearance. 
Chelifori well developed, scape two-jointed, no setous cushion at the base of the dactylus. 
Palps reduced to a knob. 
Oviger ten-jointed, without claw or denticulate spines. 
Legs densely clothed with fine sete, propodus with several strong spines ventrally ; one or two 
of the proximal ones are much the largest.
