lateral parts in all these segments acutely produced. Ocular lobule unusually 
produced, linguiform; visual elements imperfectly developed. Antennae and oral 
parts as in the 2 preceding species. Second pair of legs resembling in structure 
those in C. undata, though somewhat more slender. Uropoda with the stem 
coarsely serrate on both edges, rami unusually small, the inner one scarcely 
exceeding 1 / 3 of the length of the stem, and armed with only 4 spinules. Colour 
dark red. Length about 6 mm. 
Adult male exhibiting the usual sexual differences from the female, being 
much more slender, and having the carapace shallower, with the dorsal protu¬ 
berances less produced. Length nearly 7 mm. 
Remarks. —Though nearly related to the 2 preceding species, as regards 
the structure of the several appendages, this form is at once recognizable by the 
densely crowded conical protuberances occurring on the carapace and giving it 
a very rough appearance, a character which has given rise to the specific name 
horrida. Moreover the anterior part of the carapace is unusually exserted, and 
the ocular lobule of a peculiar form. 
Occurrence. —This form, too, was at first found off the Lofoten Islands, 
and subsequently I have also met with it in several other places on the Nor¬ 
wegian coast, for instance in the outer part of the Hardanger Fjord, at Christian- 
sund, and in the Trondhjem Fjord. It is generally found in depths ranging from 
100 to 300 fathoms, on a soft muddy bottom. This species also has not as yet 
been recorded out of Norway.

Specific Characters. — Female. Body rather short and stout, with the 
anterior division greatly tumefied. Carapace large and swollen, evenly vaulted 
above, and having the anterior part but slightly exserted, surface uneven owing to 
scattered nodiform protuberances, which laterally have a tendency to arrange them¬ 
selves in longitudinal rows; pseudorostral projection short and obtuse, subrostral 
corners well marked. The first 2 pedigerous segments elevated dorsally to pro- 
curved lamellae, the 3 succeeding ones, like the 4 anterior caudal segments, with 
a pair of slight dorsal tubercles. Ocular lobule oblong oval in form, visual 
elements imperfectly developed. Antennae and oral parts as in the 3 preceeding 
species. Second pair of legs with the terminal joint about the length of the
