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 coxae 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 coxae together, but the remainder of the 

 appendage is much more slender. The proportions of the two tibiae 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 setae. The 

 propodus, which is curved, has a row of them along its ventral margin, separated by 

 rather wide intervals ; several setae are scattered dorsally. The terminal claw is 

 stout and is accompanied by two slender auxiliaries about one-third its size. A few 

 setae are scattered on other parts of the appendage, but they do not form a prominent 

 feature. 



The Genital apertures are distinct on the second coxae 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 Ameiger 

 (13), retaining as far as possible the words of Jarzynsky. Certain characters made 

 use of by Professor G. 0. 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 Eegions are now described.
