Genus Genetyllis, Malmgren, char, emend. Bergstrom. 



Body short and rather broad. No median tentacle. Four pairs of tentacular cirri, 

 either slender or spindle-shaped. The first tentacular segment is free of the head, and 

 the first two tentacular segments are fused into a single structure carrying three pairs 

 of tentacular cirri and a pedal lobe with bristles but no acicula. Dorsal cirri large and 

 foliaceous ; the ventral cirri are also foliaceous and curve ventrally upwards and down- 

 wards from behind the foot. The anal cirri are large and cylindrical. 



Genetyllis polyphylla (Ehlers). 



Bergstrom, 1914, p. 161, fig. 55, with synonymy. 

 Occurrence. St. WS 27 (4); WS 123 (2); MS 64 (7). 



Specific characters. All the present specimens are damaged and the largest 

 measures 16 mm. by 2 mm. for 54 chaetigers. The colour is reddish yellow with orange 

 cirri. The head is rounded and longer than broad. There is a pair of large eyes. No 



nuchal papilla. The tentacular formula is i + 5 \- B -^j {fide Bergstrom). The dorsal 



cirri are very asymmetrically cordiform with the apex pointing towards the dorsal 

 median line. The ventral cirri are oval with the long axis pointing upwards and down- 

 wards. The bristles have short, rather broad end-pieces. 



Genus Eteone, Savigny 



Body elongate with numerous segments. Head triangular, truncated in front. Four 

 tentacles, and on the first segment two pairs of tentacular cirri. The second segment has 

 a foliaceous ventral cirrus, but no dorsal cirrus: it may have a pedal lobe with or 

 without bristles. Dorsal and ventral cirri foliaceous. Proboscis smooth or carrying 

 lateral rows of papillae. 



Eteone sculpta, Ehlers. 



Bergstrom, 1914, p. 195, text-fig. 73 a, b, with synonymy. 

 Occurrence. St. WS 755 (i). 



Specific characters. The present specimen measures 19 mm. by 2 mm. for about 

 160 chaetigers. There are purple transverse segmental bands across the back and the 

 cirri are yellow. The head is more or less rectangular, slightly longer than broad. The 



proboscis is smooth. The tentacular formula is O — . The second segment has bristles, 



but no dorsal cirrus. The dorsal cirri are broadly oval, thick and at their base about as 

 broad as long. In the bristles one side of the articular cup is produced into a long 

 finely denticulated process. 



Remarks. Augener (1932 a, p. 26) is, I think, justified in making E. rubella, Ehlers, 

 a synonym of this species. 



Genus Lopadorhynchus, Grube 



Body short, head broader than long, two eyes and four tentacles. Two pairs of 

 tentacular cirri and sometimes a third rudimentary pair on a single segment, which is
