tooth-like process. The hand is large, but neither so 
broad or long as the wrist ; the palm is rounded but not 
defined ; and the finger is distinctly serrated upon the 
inner margin. The second pair of legs have the wrist 
and hand but slightly dilated : the palm is rounded off, 
imperfectly defined, and furnished with a few hairs. 
The finger, like that of the preceding pair, is serrated 
upon the inner margin. In the last three pairs of legs 
the thighs are less developed than ordinarily, the last 
pair of legs are but moderately prolonged. The three 
pairs of caudal appendages extend to nearly the same 
length, and consequently have the peduncles and their 
branches gradually decreasing in their relative lengths 
successively. The terminal tail-piece is furnished near 
the apex with one or two long, somewhat peculiarly 
formed hairs, and also one or more short plumose cilia. 
Under the microscope the skin is seen to be covered 
by numerous minute points as in the vignette at *. 
This species was first found by our friend the late Mr. 
Howard Stewart, Sub-Curator of the Hunterian Museum 
of the Royal College of Surgeons, under the Hoe, 
Plymouth, in a sponge. Mr. Loughrin has also sent us 
specimens from Polperro. It has also been dredged from 
seventy to ninety fathoms of water, sixty miles east of 
the Shetland Islands ; and Costa took his animals, which 
we consider to be identical with our specimens, at Naples: 
it has therefore been necessary to sink the name of 
Lembos Damnoniensis , as first proposed, for the older 
name of Costa. Among the specimens which we have 
received were some without any tooth upon the carpus 
of the anterior pair of gnathopoda — these may possibly 
be females.
