and thirteen minute hairs scattered over the surface anterior to 
these. The eye is vestigial though visible, low down on the genal 
process which is sharply pointed behind. At the extreme an- 
terior end of the fore-genz there are four ctenidial spines, two 
on each side. The posterior pair are the longer and are curved 
backward. The rostrum is short, reaching about one-fourth the 
length of the anterior coxe. The occiput bears nine bristles on 
either side and a row on the posterior margin of twelve. This 
marginal row ends well down on the post gena in a very long and 
heavy bristle. 
Thorax.—The pronotum bears a ctenidium of forty-two spines 
on its posterior margin. There are about twelve bristles on each 
side of this sclerite. The mesonotum bears about nine bristles on 
a side in addition to a posterior marginal row of ten. The meta- 
notum bears ten bristles on a side in addition to a posterior row 
of sixteen. The mesepisternum bears nine bristles and the mese- 
pimeron three. The mesosternum is protuberant below and bears 
no bristles. The metepisternum is very small and bears four 
bristles, while the metepimeron is much larger, bearing nine. 
The metasternum is similar in form to the mesosternum but is 
somewhat larger. 
Abdomen.—No abdominal tergite bears ctenidial spines. How- 
ever, dorsally, the bristles of the posterior marginal rows become 
more numerous and form structures which are analogues of the 
pronotal ctenidium. The numbers of bristles in these rows for 
the first seven tergites are as follows: 14, 12, 8, 8, 8, 8,4. The 
bristles, other than these on the tergites are as follows: On the 
first there are nine, arranged in two rows. On the remaining 
tergites there is one row of large bristles on each, as follows: 
4, 6, 5, 6, 6, 5. There are no bristles on Sternite III. Sternites 
IV—VII bear the following on each side: 3, 3, 3, 6. The ante- 
pygidial bristles are one on each side, mounted on conical pro- 
tuberances. 
Legs.—The fore femur bears proximally one and distally two 
bristles on its ventral (internal) edge. On the dorsal edge, api- 
cally there is a prominent curved spinous bristle. The mid and 
hind femora are similar except that apically on the outer face 
there are three additional bristles on each. The tibie bear, on
