Vanadis antarctica (Mcintosh). 



Alicopa antarctica, Mcintosh, 1885, p. 175, pi. xxviii, figs. 2, 3, 4; pi. xxxii, fig. 12. 

 Vanadis antarctica, Benham, 1921, p. 58, pi. viii, figs. 61-63, with synonymy. 



Occurrence. St. 334 (i); 362 (i); 373 (i); 461c (i); 527 (3); 533 (i); 569 (i); 579 (i); 590 (i); 

 591 (i); 619 (i); 1148 (i); WS 200 (i); WS 408 (i); WS 411 (i); WS 537 (i); WS 550 (i); WS 551 

 (2);WS552(i). 



Specific characters. Four pairs of tentacular cirri, followed by about a dozen seg- 

 ments in which the feet are reduced in size, being smaller than the normal feet of the 

 rest of the body. This area with reduced feet is nearly always pigmented and gives the 

 animal a characteristic appearance of having a pigmented neck. In the female the first 

 two feet have the dorsal cirri converted into seminal pouches. The mouth of the pro- 

 boscis has only rather short papillae and is devoid of the pair of lateral tentacle-like 

 processes present in V. formosa. The pigmented neck is followed by a short unpig- 

 mented area of about three segments, and this again by about three pigmented seg- 

 ments. Behind this the pigment is usually confined to the lateral glands and does not 

 spread over the dorsum. The arrangement of the glands and their accompanying pig- 

 ment is irregular up to about 30th-50th segment, behind which there is a pair of glands 

 in each foot. There are the usual foliaceous dorsal and ventral cirri on the feet, and a 

 lanceolate pedal lobe ending in a projecting aciculum and a small cirriform process. 

 The bristles are very long and delicate and the articulation between shaft and blade 

 very diflicult to see. 



This is a fairly large species with a breadth of about 5 mm. My most complete 

 fragments measure about 150 mm. in length. 



Vanadis formosa, Claparede. 

 Fauvel, 1923, p. 205, fig. 77 a-c. 



Occurrence. St. 404 (2); 407 (2); 701 (i); 704 (i); 705 (i); 713 (2); 714 (i and 2 juv.). 



Specific characters. Four small digitiform lateral tentacles and a median tentacle. 

 Three pairs of tentacular cirri. The mouth of the proboscis has, in addition to a number 

 of rather short papillae, on each side a long tentacle-like process. In the female the 

 dorsal cirri of the first two feet are converted into large globular seminal pouches. In 

 the male the first foot is reduced to a dorsal and ventral cirrus. The remaining feet have 

 a lanceolate pedal lobe with a long, projecting aciculum, foliaceous dorsal and ventral 

 cirri and numerous very fine compound bristles. The pedal lobe ends in a small cirri- 

 form process. Every chaetiger, except the first three, carries a large dark brown gland. 



Remarks. In the colder waters of the southern hemisphere the place of this species 

 is taken by V. antarctica (Mcintosh). 



Vanadis crystallina, Greeff . 



Fauvel, 1923, p. 206, fig. 77 d, e. 



Occurrence. St. 708 (2); 709 (i). 



Specific characters. A small thread-like species with up to about 150 segments. 

 The proboscis carries a pair of long lateral processes. Four pairs of tentacular cirri.
