To the elaborate representation published by Sars only a couple of remarks may be made. - 

 Fig. 9b exhibits the outline of the front cephalic area in a co-type presented by Sars; it shows the 

 area broader in proportion to length with the end more broadly incised than in Sars' fig. 2; the spec- 

 imens presented by him agree with each other in the shape of the area. Fig. 9 a, which represents 

 the head of an "Ingolf" specimen (from Stat. 78), shows a somewhat different shape of the area; it has 

 the lateral margins straight and converging to near the end. which is broadly emarginate with the 

 lateral corners rounded. — The antennal squama (fig. 9 a) is very peculiar in this species; it is moder- 

 ately slender, long, a little to much more than half as long as the diameter of the third joint, and it 

 reaches considerably beyond the end of fourth joint, and terminates in a couple of setae on the obtuse 

 or truncate end. — It may be emphasized that, excepting the difference mentioned in the shape of 

 the front cephalic area, my specimens agree well with the figures drawn by Sars. 



Occurrence. Taken by the "Ingolf at two somewhat deep stations in the warm area. 



Davis Strait: Stat. 24: Lat. 63°o6' N., Long. 56°oo' W., 1199 fath., temp. 2-4°; 1 spec. 



South-West of Iceland: Stat. 78: Lat. 6o°37' N., Long. 27°52' W., 799 fath., temp. 4-5°; 2 spec. 



Distribution. Sars has recorded E. furcata from off Lofoten, 100 — 120 fath., and from Sta- 

 vanger Fjord. — I have not found it mentioned by any other author. 



101. Eurycope mutica G. O. Sars. 

 (PI. XIII, figs. 10 a— 10 c).

To the representation of Sars three new figures are added, and a few remarks must be made. 



The antennal squama (fig. 10 a, ex) is very characteristic; it is shaped as a small tubercle 

 scarcely as long as broad, but distinctly marked off, and it terminates in a very conspicuous, thick, 

 generally straight, stick-shaped seta terminating in a hair. — The abdominal operculum in the male 

 has been incorrectly figured by Sars; the more distal part of both the median lamella and the lateral 

 plates are curved upwards — seen from below (fig. 10 b) downwards — but the lateral plates reach 

 scarcely to the end of the lamella, while in Sars' figure they reach considerably beyond the lamella; 

 furthermore each pleopod of the lamella terminates in two lobes (fig. 10 c), the inner broader and obliquely 

 rounded, the outer somewhat or very narrow. — As to other features E. mutica, which is a very char- 

 acteristic species, has been well figured and described by Sars. 



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