joint is small, and the proportions of the remainder are 4:3:1°5:3. The terminal 
joint is well supplied with sete on the outer side, and the preceding one is similarly, 
but less well, provided. Elsewhere they are scanty, a few on the third, and only an 
occasional one on the second. 
The Oviger is ten-jointed, and rises from a small process immediately in front of 
the first pair of lateral processes (fig. 4b.) The first joint is very small, the two 
following are longer and subequal, the third having as usual a very oblique termination. 
The fourth and fifth joints are subequal, and each much longer than the first three 
together ; the sixth is half as long as the preceding. Of the four terminal joints the 
first is the longest, the rest differ but little, but the last is longer than the others, 
and bears a terminal claw with some half-dozen teeth. A limited number of sete 
occur on all the joints from the end of the fourth. The denticulate spmes are not 
very numerous, 8: 5:4: 5, and consist of a slender tapering shaft with from five to 
seven lateral teeth ; the second from the base is strongly developed, the rest graduated 
to nothing (plate X., fig. 10). 
The Legs are long and very slender; they are about 9mm. long. Of the three 
coxze the second is longer than the other two together, the proportions of the remaining 
joints being 4: 4°5:7:1:1°5. The terminal claw is more than half as long as the 
propodus, and is accompanied by two slender auxiliaries. The entire limb is rather 
thinly clad with sete, which, as usual, are most abundant on the second tibia. The 
propodus bears ventrally a row of comparatively strong spines, not very regular, the 
middle ones being generally best developed. 
This is not a mature form, and the sexual apertures cannot be distinguished. I 
am unable to identify it with Nymphon hiemale, though it occurs in the same locality, 
and feel compelled to regard it as an independent species.

(Plate IV., fig. 1; Plate X., fig. 11.) 
Specific characters :— 
Body robust and with the appendages covered with long and fine setz ; lateral processes close 
together. 
Ocular tubercle rather tall, with four eyes at summit. 
Palp five-jointed, proportion of last three 6 : 2 : 3. 
Oviger ten-jointed, denticulate spines not numerous, having five to seven lateral teeth on each side. 
Legs short, with a strong terminal claw and two well-developed auxiliaries. 
Body very robust and, with the appendages, covered with long and fine sete. 
The lateral processes are close together, and these, being stout, give the body a compact 
ovoid form. 
The Cephalon is short, much expanded, and the neck, which thereby becomes 
distinct, is scarcely a real constriction, the expanded portion being divided into two 
distinct lobes, bearing a few long sete distally. Similar sete occur dorsally on
