EUNICIDAE 145 



Ephesia antarctica, Mcintosh. 



Mcintosh, 1885, p. 361, pi. xlix, fig. 5; pi. xxHa, figs. 22-23. 

 Ehlers, 1908, p. 107, pi. xliv, figs. 7-13. 



Occurrence. St. WS 212 (i). 



Specific characters. Up to about 50 mm. in length. The body is papillated. I can 

 see only one pair of reniform eyes. Bristles compound with rather short pointed blades. 



Remarks. Except that I can see only one pair of eyes I cannot separate this species 

 from E. peripatiis (Claparede). Unfortunately the only specimen of Claparede's species 

 in the museum is of little use for purposes of comparison, but the descriptions of the 

 northern species seem to be equally applicable to the southern.

Occurrence. St. WS 763 (3); WS 764 (1); WS 776 (numerous); WS 788 (i); WS 852 (3). 



Specific characters. A full-grown example of this species measures about 300 mm. 

 by 6 mm. at the widest part for about 200 chaetigers. The prostomium is bilobed and 

 the tentacles are indistinctly annulated. The gills usually begin at the 6th chaetiger and 

 are continued to within three or four segments from the end of the body. In the anterior 

 third of the body the maximum number of filaments is usually eight or nine, but there 

 may be as many as 14 : in the middle region the number drops to four or five, and in the 

 hinder region it increases again to seven or eight. In the latter region the filaments are 

 set very close together and the gills often have a bushy appearance, as Mcintosh 

 indicates. The feet are supported by two large acicula which are black except towards
