antepenultimate one and comparatively narrower than in the 2 preceding species. 
Uropoda with the stem slightly serrate on both edges, inner ramus exceeding 
half the length of the stem, and armed with 5 spinules. Colour whitish with a 
faint greenish tinge. Length 5 Vs mm. 
Adult male much more slender than the female, with the carapace shal¬ 
lower, and scarcely at all vaulted above. Appendages exhibiting the usual trans¬ 
formation. Length 6 V 2 mm. 
Remarks. — This form is allied to C. horrida, but may be readily distin¬ 
guished by the somewhat different form of the carapace and the less numerous 
and more obtuse protuberances clothing its surface. Moreover the stem of the 
uropoda is considerably shorter, and the colour of the body very different. The 
species described by the present author from the Challenger Expedition as C. 
nodulosa strongly resembles the Norwegian form in its external appearance; but 
the remoteness of the locality (Kerguelen Islands) must put its specific distinctness 
beyond all doubt. 
Occurrence. —I have found this species along the whole south and west 
coast of Norway, as far north as the Lofoten Islands, and in some places, for 
instance in the Trondhjem Fjord, very abundantly. It occurs in depths ranging 
from 60 to 100 fathoms, muddy clay. The species is hitherto only known from 
the Norwegian coast.

Specific Characters. — Female. Body comparatively more slender in form 
than usual, with the anterior division less tumefied. Carapace of moderate size 
and evenly vaulted above, with the anterior part but slightly produced, surface 
nearly smooth, with only slight traces of a few obtuse protuberances in the anterior 
part of the dorsal face; pseudorostral projection comparatively short, subrostral 
corners small, though distinct. The first 2 pedigerous segments less narrow than 
usual, and having the posterior edge but slightly elevated dorsally; the succeeding 
segments, as also the caudal ones, perfectly smooth. Terminal joint of 1 st pair 
of maxillipeds less rudimentary than usual, oval fusiform in shape, and finely 
ciliated on the edges, tip carrying 2 unequal spines. Second pair of maxillipeds 
with the seta issuing from the inner corner of the basal joint peculiarly trans¬ 
formed, penultimate joint not nearly so large as in the other species. Structure
