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 Vs 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 oi 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 lamella?, 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. Antenna? and oral parts as in the 3 proceeding 

 species. Second pair of legs with the terminal joint about the length of the
