I have received from Professor Verrill a second species of this curious genus 
from the deep-water dredgings of the Fish Commission, which may be advan- 
tageously described in connection with the last. Body somewhat more robust 
than in the last. Oculiferous segment longer than the two following taken to- 
gether, much swollen in front, so that there appears to be a distinct neck, which 
is, however, scarcely narrower than the rest of the body. Oculiferous tubercle 
obtuse, much less prominent than in the last ; ocelli nearly the same, lighter 
colored. 
Rostrum as long as the oculiferous and two succeeding segments taken to- 
gether, somewhat fusiform, slightly swollen a little behind the middle, expand- 
ing very slightly near the tip. 
* Antenna" (Fig. 21) extremely slender ; the two basal joints barely extend 
beyond the tip of the rostrum. Chelæ rather slender, scarcely swollen ; claws 
much longer and more slender than in the preceding form, and decidedly 
curved towards their tips. Along the middle part of their cutting edges they 
are finely but very irregularly serrate. 
Palpi in the male nearly as in the preceding species; in the female, still 
smaller and more rudimentary. 
Accessory legs (Fig. 25) much as in the last species, much smaller and less 
spinose in the female. In the male the sixth joint is sub-globose at its distal 
extremity, where it is surrounded by a tolerably definite circlet of very strong 
tapering, acute, backward-pointing spines or hooks, by means of which the egg- 
„nass is securely held. 
Legs more slender than in the former species. Tarsus usually with a larger 
spine at the lower distal angle. Spines of the propodus far less numerous than 
in the last ; there are usually three larger ones on the basal half of the joint, 
followed after a naked space by three or four shorter ones, and these by a pair 
of divergent slender longer spines. Dactylus about one half the propodus. 
Surface everywhere finely tuberculose. Hairs absent from body, and less 
numerous on legs than in the last. On the legs (as in the preceding spec 
the hairs are longer and more slender on the upper side. They have on the 
outer joints a very peculiar structure; along their outer margins are a number 
of more or less prominent barbs pointing towards the tip of the spine.
