broad at the base, but narrowly exserted at the tip, extending beyond the distal 

 joint, marginal setse 4 in number. 



Male almost of same size as the female, but of more slender form. An- 

 terior antenna} strongly hinged, with the last joint of the proximal part consider- 

 ably dilated, distal part terminating in a claw-like point. Outer ramus of 3rd 

 pair of legs very powerfully developed, with all the joints considerably thickened 

 and having the spines very coarse, setse of inner edge short and spiniform; inner 

 ramus transformed in the usual manner. 4th pair of legs likewise with the outer 

 ramus much coarser than in female and with the setae of the inner edge spiniform. 

 Last pair of legs very small, with the inner expansion of proximal joint obsolete. 



Colour dark yellowish brown. 



Length of adult female t.30 mm. 



Remarks. This remarkable form was first described by Buchholtz from 

 the German Arctic Expedition, but was erroneously identified with Miiller's Cyclops 

 minuticornis, for which reason Norman proposed for it a new specific name, viz., 

 horrida. It is, one of the largest species of the genus, and is moreover easily 

 recognised by the strong spinous armature of the body, which latter character has 

 given rise to the specific name proposed by Norman. 



Occurrence. I have found this form rather abundantly in the upper part 

 of the Christiania Fjord in a depth of from 10 to 20 fathoms, muddy bottom. 

 It also occurs occasionally both of the south and west coasts of Norway at least up 

 to the Trondhjem Fjord, and Th. Scott records it moreover from the Finmark coast. 

 The specimens are in most cases so densely coated with mud, that the peculiar 

 spinous armature of the body is only faintly traced. In some cases, however, 

 the body appears cleaner, so as to reveal the regular arrangement of the spines 

 more clearly. The movements of the animal are rather clumsy, and, as in most 

 other species, are effected in a somewhat jerking manner. 



Distribution. British Isles (Brady), Greenland (Buchholtz), Polar islands 

 north of Grinnels Land (2nd Fram Expedition), Franz Josef Land (Scott), off 

 Bear Island and Spitsberg (Scott).

Specific Characters. Female. Body resembling in its general form that 

 of the preceding species, and having a rather similar dorsal armature. Cephalic 

 segment, however, somewhat different in shape, bulging considerably to each side 

 in its posterior part, and having the lower edges produced in front to rounded
