The trunk slender. 
The proboscis long, thick, swollen in two places. 
The oculiferous tubercle rather high, anteriorly steep, posterioriy sloping; the foremost ocelli large, 
pyriform, the hindmost ones very small, oval, lying close to the emarginate hinder edge of the 
foremost eyes.

The claw small, scarcely exceeding half the length of the second tarsal joint,

Occurrence. The Ingolf-station 64, that is the northern Atlantic south of Iceland, 62? 06' 
Lat. N. 19” 00' Long. W., 1041 fath. Bottom temperature 371. Only one single specimen, a full- 
grown female.

I suppose the Co/ossenders colossea of Wilson to be different from the Co/lossenders gigas of 
Hoek, and still more decidedly different from the species of the same name of Schimkéwitsch. 
Occurrence. The Ingolf-stations are 11 and 18, the former being in the Denmark Strait, 
642 34' Lat. N. 312 12' Long. W., 1300 fath.; the latter in the Atlantic, 61" 44' Lat. N. 30% 29 Long. W., 
1135 fath. Three specimens were taken, the largest of which of a length of 63mm, 
Distribution. Wilson has this species from the eastern coast of North America, from 
41? 33' Lat. N. to 38? 45' Lat. N., and from 65” 47' To! Long. W. to 73? 10' 30” Long. W. from depths 
between 524—1186 fath. According to my conception of the species this species is only known from 
the Ingolf, and the places stated by Wilson.
