PYCNOGONIDA. 15 
on the opposite side distally. The seventh, eighth, and tenth joints are sub-equal 
in length, and the ninth is a little shorter. The arrangement of the sete is the same 
as on the sixth joint, except that the distal group on the outer side increases on each 
joint, so as to involve the whole of it. The setze on the five terminal joints are very 
long and quite simple. 
The Legs are very stout, and some 36mm. in length. The first coxe are about as 
long as their corresponding lateral processes ; the second are longer, and, in the female, 
bear a conspicuous enlargement ventrally near the distal extremity, upon which the 
large genital openings occur ; these are on all the limbs. The third coxe are about 
the same size as the first. The three following joints differ but little in size, being 
proportionally as 8°5:9:9°5. The tarsus is very small, and the propodus is about 
a quarter the length of the second tibia. The entire limb is clothed with sete. 
Dorsally the three coxze each bear a prominent distal fringe of long sete. The first 
has two lateral bands in addition, while the other two are more completely clothed. 
Ventrally the third coxa is partially covered with small sete, and has a prominent 
distal fringe of longer ones, the other two only possess a distal fringe of short 
sete. On the femur the dorsal surface is covered with long sete, which also form a 
prominent distal fringe ; the ventral surface bears only small sete, but on each side 
there is a band of the large ones just below the well-developed lateral line. This 
arrangement holds good on the two tibiz, but the setee are much more thickly 
set. At the distal extremity of the second tibia the setee become spinous ventrally, 
and as spines form the distal fringe on that side. The ventral surface of the tarsus is 
clothed with spines which are large distally ; dorsally there is a fringe of sete only. 
The propodus is covered dorsally with sete of more moderate length than those on 
the appendage generally ; laterally they are smaller still, and along the ventral 
aspect there is a row of about a dozen strong spines, a little irregular in size, 
but one or two of the proximal ones are much the largest. There is no projection of 
the propodus beyond the insertion of the terminal claw, which is stout and rather 
more than half the length of the joint that bears it. It is accompanied by two small 
auxiliaries, 
The single specimen is an adult female, and contains ripe ova.
