In 1887 (1. c.) I stated that the eye or the ocelli in this species had not been mentioned in the litera- 

 ture, and that I found two ocelli. In his Account Sars says: "Eye distinct, semicircular and somewhat prom- 

 inent", which is misleading. It is not the eye but the ocular lobe which is "semicircular and somewhat prom- 

 inent"; on each side of this lobe I have constantly found an ocellus, but it was impossible to find any dorsal 

 ocellus between the lateral pair, while on the end of the lobe one finds with difficulty two oblong, semi- 

 vertical ocelli lying close together in the median line. Therefore Sars' figures O and O x on PI. LXI present a 

 curious difficulty, as his fig.O, the lobe seen from the left side, has two ocelli respectively on the side and at 

 the end, consequently only two pairs, but his fig. O x, exhibiting the lobe from above, has an apical pair, 

 a lateral pair and a single, large, dorsal ocellus at the base. In my specimens from various localities such a 

 median dorsal ocellus does not exist. 



Sars points out that the dactylus of second pair of maxillipeds has "four strong spines increasing 

 in length from before backwards". This is a very fine character which I can verify, as I found the four spines 

 increasing backwards in length both in a specimen from Norway and in one of the anomalously coloured 

 females from Lat. 63°46' N. (fig. 1 a). So high a number of spines has not been found by Sars in any other 

 species from Norway, nor by me in any species from the "Ingolf" area excepting C. serratipes n. sp., but in 

 this species the second spine is much shorter than the third or the proximal spine. 



The "Ingolf" specimen and the male from Lat. 63°i5' N. have the red colour of the body well pre- 

 served and no dark dots. But the 6 speximens of both sexes from Lat. 63°46' N. are at least now only light 

 reddish, and they have a large number of dark-brown, mostly very oblong dots spread partly irregularly 

 on the body ; these dots are sometimes so numerous on certain parts of the carapace that they are nearly 

 confluent. It may be added that I found the joints in third maxillipeds and in first and second legs of one of 

 these dotted females agreeing well as to shape and marginal teeth with Sars' figures. 



Occurrence. Taken by the "Ingolf" at a single station. 



North of Iceland: Stat. 128: Lat. 66°5o' N., Long. 20°02' W., 194 fath., temp. 0.6°; 1 specimen. 



C. rubicunda has been recorded from three places at northern West-Greenland, viz. Olrik Bay, Lat. 

 ca. jj° N., 15 — 20 fath. (Ortmann) ; Kekertak, Lat. 69°58' N., 60 — 70 fath. (H. J. Hansen), and off Holstens- 

 borg, Lat. 66°59' N., Long. S5° 2 7' W., 57 fath. (Norman). The "Thor" has secured it at the following two 

 localities. 



South-West of Iceland: Lat. 63°46' N., Long. 22°56' W., 80 fath.; 3 males, 3 females. 



South of Iceland: Lat. 63°I5'N., Long. 22°23' W., 114 — 172 fath.; 1 male. 



Distribution. Recorded from the northern part of the Sound and the entrance to Odense Fjord 

 (Meinert), a few places in Kattegat, 13 to 30 fath., and three places in Skager Rak, 85, 100 and 350 fath. 

 (H. J. Hansen). At Norway it has been taken at several places from Christiania Fjord to Vadso, generally 

 in 30 to 100 fath. (Sars, etc.). Sars records a single very large specimen gathered by the Swedish Spitzbergen-
