6 T. V. HODGSON. 



The Ocular tubercle lies almost in the middle of the cephalon, but scarcely clear 

 of the first pair of lateral processes. It is very stout, of no great elevation, terminating 

 in a strong cone above the four eyes. 



The Abdomen is small, cylindrical, terminating in a cone, and directed almost 

 vertically upwards. It is not articulated to the trunk. 



The length of the trunk is 5mm. (to extremity of posterior lateral processes) and 

 its extreme width is 3mm. 



The Proboscis is long and slender, scarcely 4mm. in length, flexibly united to the 

 trunk. It is cylindrical, but very slightly swollen before the middle and equally 

 slightly narrowed before its rounded extremity. The mouth is inconspicuous, but of 

 normal size. The proboscis is covered, more especially distally, with extremely 

 minute spines. 



The Legs are long and slender, attaining a length of 30mm. The first coxa is the 

 smallest, and the second is a trifle longer than the first and third together ; the pro- 

 portions of the three following joints are as 8 : 675 : 8'5 ; the tarsus is very small, and 

 the propodus, which is curved, is about a quarter the length of the femur. The entire 

 limb, as the trunk, is completely clothed with extremely minute stiff setae, which for 

 the most part are only visible with a powerful lens. On the tibia they are, however, 

 rather more conspicuous, besides being most abundant. The larger or ventral surface 

 of the tarsus is covered with short spines, but one distal one is extremely large and 

 prominent. Dorsally the propodus is covered with the minute stiff setse, ventrally there 

 are at the proximal end of the joint three to five very large spines, the remainder of 

 that surface being occupied by a band of much smaller though still conspicuous 

 spines of rather irregular size. A prominent heel projects over the insertion of a 

 powerful terminal claw and its two auxiliaries, these latter being about half its length, 

 but much more slender. The second coxa bears dorsally, just beyond the middle of its 

 length, a tubercular enlargement, which is perforated by a glandular opening. 



The genital apertures occur on a transverse ridge at the extremity of the second 

 coxa of every leg. Ventrally, in the angle formed by the first pair of lateral processes 

 and the trunk, there is a very small but distinct process on each side, exactly in the 

 position where the oviger should be. 



This type specimen is a female, and was taken off Flagon Point in Winter Quarters 

 in 5-20 fm., on very rough ground. 



Two other females were taken, one slightly larger than the type came from 

 125 fm., on a bottom composed of small stones and organic debris ; the other is much 

 smaller, but the precise point at which it was captured in Winter Quarters remains 

 uncertain. A fourth specimen is a male, and is to a considerable extent overgrown 

 with polyzoa. This specimen was taken at the same time and place as the type. It 

 is sexually mature, and the genital apertures occur on the three posterior legs only. 

 The ovigers are well-developed, but unfortunately only four basal joints remain on 

 either side. They arise in the angle formed by the first lateral process and the trunk,
