all that is visible. A prominent claw terminates the appendage. The denticulate 
spines are few in number, two on each of the first three joints. They are worn, and 
all that remains is a slender shaft of uniform diameter with three terminal teeth, of 
which the middle one is the largest. 
The Legs are short. The three cox are short and stout, the second is by a very 
little the longest, but the first has nearly twice its diameter; it also bears a tubercle 
smaller than, but similar to, those borne on the middle line of the trunk. The femur 
is stout, and not so long as the three coxze together, but the remainder of the 
appendage is much more slender. The proportions of the two tibie are as 3 to 2, 
the tarsus and propodus together being as long as the second tibia. The tarsus is a 
very small joint, its ventral surface being covered with minute spinous sete. The 
propodus, which is curved, has a row of them along its ventral margin, separated by 
rather wide intervals; several sete are scattered dorsally. The terminal claw is 
stout and is accompanied by two slender auxiliaries about one-third its size. A few 
setee are scattered on other parts of the appendage, but they do not form a prominent 
feature. 
The Genital apertures are distinct on the second cox of the last pair of legs only, 
and this joint is much swollen in consequence. 
This species, of which there is only a single specimen, was found by Mr. Kirk- 
patrick on a sponge. Winter Quarters, at a depth of 178 fm., 7 Aug., 1902. 
COLOSSENDEIS. 
Body ovoid or elongate, with the lateral processes close together or widely separated, as a general 
rule without segmentation. Cephalon small. Eyes well developed or absent. 
Proboscis very large, often much longer than the body, and movably articulated to it. 
Chelifori very rarely present, rudimentary. 
Palps very long, 10-jointed, third and fifth joints the longest, more or less setose. 
Ovigers very long, 10-jointed, fourth and sixth joints the longest, the last four joints bearing 
several rows of spines usually dentate. A terminal claw. 
Legs without auxiliary claws ; the three coxal joints short. 
Abdomen of moderate dimensions, movably articulated to the trunk, sub-clavate. 
Genital apertures on the second coxa of all the legs. 
I defined this genus in comparison with Decolopoda in the Zoologischer Anzeiger 
(13), retaining as far as possible the words of Jarzynsky. Certain characters made 
use of by Professor G. O. Sars (25) have been incorporated, since his definition has 
become inapplicable in certain important features. 
No less than eighteen species and two varieties have been described. Through 
the generosity of Professor E. L. Bouvier I have been permitted to examine the 
collection of Colossendeids made by the ‘ Travailleur’ and ‘ Talisman,’ the description 
of which is not yet published. The identity of these species with the known species, 
or otherwise, has not yet been fully established, but four new species from the 
Antarctic Regions are now described.
