APSEUDES LATREILLII, 
Specific character. Body smooth, destitute of hairs on the sides. Head 
terminating in front in a deflexed point. Terminal segment of the tail not 
more than half the length of the preceding portion of the pleon. First pair 
of gnathopoda moderately large, the hand produced at its lower angle into a 
strong finger, which is densely hairy, but destitute of tubercles or spines, as 
is also the true movable finger. 
Length one-fourth of an inch. 
Rhea Latreillii (2) Munn Epwarps, Ann. Sci. Nat. V. xiii. p. 288, pl. 13a. 
THE specimen from which the accompanying figure is 
drawn bears so great a resemblance to Milne Edwards’s 
figure of Rhwa Latreillii that we have no doubt as to the 
identity of the two animals. The deflexed rostrum, or 
advanced point of the head, the comparatively large size 
of the second pair of feet, the more slender hand with 
the smooth fingers in the first pair of limbs, are all 
characters observable in both. 
The small central point of the head, or rostrum, is 
slightly down-curved. The orbital process is produced 
to a pointed apex. The superior antennz have the pe- 
duncle smooth, and the secondary appendage of the 
flagellum scarcely half as long as the primary. The 
inferior antenna reaches but little beyond the peduncle
