POLYNOIDAE 89 



Remarks. I regard these specimens as rather doubtfully belonging to Augener's 

 species from the Abrolhos Bank off Brazil. The elytral vesicles appear to be similar, but 

 in Augener's species they are more numerous. The present specimens are probably 

 southern representatives of Hartnothoe impar, Johnston.

Occurrence. St. 371 (7); 456 (numerous); WS 27 (3); WS 225 (2); WS 239 (i); WS 244 (4); 

 WS 583 (i); WS 762 (3); WS 764 (i); WS 782 (3); WS 784 (2); WS 801 (2); WS 811 (i); WS 824 

 (2); WS 82s (5); WS 834 (2); WS 837 (2); WS 867 (4); MS 65 (I). 



Specific characters. There are 37 segments. The elytra are mottled with reddish 

 brown and the back and feet are banded to a variable extent with brown markings. 

 There are numerous, minute, conical, acuminate tubercles on the elytra, and in addition 

 the hinder border may be provided with several large, vesicular tubercles. These are 

 often absent. Furthermore, the external edge of the elytra may or may not be furnished 

 with a fringe of cilia. The dorsal bristles may be strongly pectinated or almost smooth. 

 The ventral are toothed and as a rule bidentate. Specimens with unidentate ventral 

 bristles are, however, found, and also intermediate specimens in which one or two 

 faintly bidentate bristles may be seen in neuropods bearing unidentate bristles. 



Remarks. Almost the only constant specific character that I can find after examining 

 a large series of this species is the presence of the numerous, minute, conical acuminate 

 tubercles on the elytra. The large haul of specimens from off Bouvet Island yielded a 

 number of examples with unidentate ventral bristles.

Harmothoe lagiscoides, Bergstrom, 1916, p. 282, pi. ii, figs. 2-3. 



Augener, 1932 a, p. 15. 



Occurrence. St. 456 (8); WS 764 (6). 



Varietal characters. The number of segments is about 40, and the pigmentation 

 is more intense than in H. spinosa. A few of the terminal segments are left uncovered 

 by the elytra, and the hinder end is noticeably more tapered than in the stem-form. 

 The hinder border of the elytra is furnished with a few long, acuminate spines. 



Remarks. Bergstrom and Augener have raised Willey's var. lagiscoides to specific 

 rank. In my earlier Antarctic report I included it under H. spiftosa. I have now come 

 to the conclusion that its characters are sufficiently constant to merit at any rate 

 varietal status. 



Subgenus Barrukia, Bergstrom 



As Harmothoe, except that the dorsal bristles mostly have bearded tips.
