130 DR. W. C. M'HiTTOSH ON THE ANNELIDS OF 



One example had the same whitish tubercles (containing gra- 

 nules) in its skin as observed in Nycliia cirrosa of the ' Valorous ' *. 

 Abundant in all northern waters. 



Antinoe Saesi, Kinherg, ? var. gr(enlandica, Mgrn. 



A large example, 50 millims. in length and about 20 in total 

 breadth, from Discovery Bay (the winter- quarters of H.M.S. 

 • Discovery '), in 81° 44' N. lat. 



Fig. 2. 



Head of Antinoe Sarsi, slightly magnified. 



The head of this specimen (fig. 2) differs from the ordinary form 

 in having the posterior pair of eyes in a line passing transversely 

 across the middle of the head, and therefore advanced to an un- 

 usual degree. The anterior pair are placed laterally, a little 

 behind the anterior prominence. The dorsal bristles are very 

 long, much longer than in Malmgren's figure, indeed they project 

 outward as far as the ventral. 



A Loxosoma occurred on the feet ; and on the same parts a pa- 

 rasitic Infusorial form covered the cuticle and the bristles with a 

 minute down, rising here and there on the former into little elevated 

 tufts, and evidently flourishing in great profusion. 



A. Sarsi in its ordinary form occurs in the Baltic, at Spitz- 

 bergen, Tinmark, and from the Grulf of St. Lawrence northwards 

 to G-reenland.
