two outer are large, dentiform, and have a spinule between them, while 
the terminal or inner spines are smaller, slender, and movable, and sep- 
arated from the large lateral spines by a space armed with three or four 
spinules, while the margin between the movable spines forms an obtuse, 
re-entering angle, each side of which is armed with a close-set series of 
- seven to ten slender spinules. 
The eyes are large, as broad as the rostral plate, and black. The 
antennal scale is narrowly elliptical, about three times as long as broad, 
and the margins ciliated. The prehensile edge of the dactylus of the 
large “‘raptorial limbs” (second maxillipeds) is armed with ten slender 
spines, which decrease in length distally. The bases in each of the 
three posterior pairs of thoracic legs are armed on the outer side with a 
conspicuous, acute, and somewhat hooked spine, projecting over the 
articulation of the next segment. The appendages of the antipenulti- 
mate segments of the three posterior pairs of thoracic legs are lamellar 
and broadly elliptical, though those of the anterior pair are a little 
shorter and those of the posterior pair slightly narrower than the others. 
The base of the uropods is armed above with a spinulose crest, running 
from the base to the articulation of the outer ramus, and at the distal 
end below with two dentiform spines as long as the inner ramus, below 
the articulation of which there is another but much smaller spine on the 
base. The proximal segment of the outer ramus is crested above, the 
distal part of. the outer edge is armed with a crowded series of stout, 
spiniform sete, and the lamellar terminal segment is elliptical, nearly as 
long as the base, and has its edges ciliated. The inner ramus is much 
longer and narrower than the terminal segment of the outer ramus, 
which in other respects it resembles.
