PYCNOGONIDS 279 
ceeding joints smaller (not successively); 7.10 very small. The tenth 
joint is armed with two rather long, curved, denticulate (?) spines; the 
I or 2 spines on the preceding joints appear to be simple. Oviger of the 
male about half as long again as that of the female; proportionate size of 
joints nearly the same, but 77.8, 9, and 10 turn inward (or downward if 
the appendage is carried in a horizontal position, as in fig. 7, pl. xx) 
upon 7.7, and the preceding joints at nearly a right angle. The joints of 
the terminal part of the oviger are armed with a few short, slender, simple 
' spines. 
Legs about twice as long as body: ¢.1 short, with a spine-bearing 
process on each of the distal dorsolateral corners; the male with an 
additional similar projection on the mid-dorsal line between these. The 
tubercles are also longer and sharper in the male. Second coxal joint a 
little longer than ¢c.1, broader distally; ¢.3 shorter again; f equal in 
length to coxal region, gradually increasing in breadth distally, where it 
ends in a triangular projection terminated by a short, stout spine; f. of 
female swollen, broadest in middle; 41 and #2 each about equal to f, 
rather slender, armed on the dorsal border with 2 or 3 long, slender 
bristles and a few shorter ones; ventral border of 42 with a regular 
series of short, slender spines. First tarsal joint about as long as broad, 
convex ventrally, where it bears several fine bristles; with a well-marked 
‘lappet’ dorsally. Second tarsal joint long and slender, at least five 
times as long as broad, nearly straight; dorsal surface with a series of 
spines, 2 or 3 of which are especially long and slender (about like those 
on 41 and ¢#.2); the others shorter; no distinct heel; the ventral surface 
furnished with a more or less regular row of about ro short spines. In addi- 
tion to what has been mentioned, the several joints of the leg have scat- 
tered short hairs or slender spines. Claw comparatively rather short, 
hardly half as long as #2, falciform; aux. cl. slender, half as long as c/. 
Length about 1.3 mm., extent slightly over 5 mm. The two sexes of 
' about equal size. 
Immature specimen.—The one immature specimen examined was about 
three fourths the size of the adults and more slender; otherwise it much 
resembled the female, especially in the character of its tubercular pro- 
jections and spines. It had, however, chelate chelifori, the chele being 
large and strong.
