I30 DISCOVERY REPORTS 



Genus Eusyllis, Malmgren 



Palps fused at the base. Tentacles and dorsal cirri smooth, but often appearing to 

 have annulations. The rim of the pharynx is denticulated and there is also a single, 

 anterior, pharyngeal tooth. Two rows of papillae round the mouth of the pharynx. The 

 body is very fragile.

Occurrence. St. 53 (i); 190 (2); WS 811 (2); WS 836 (3); WS 837 (i); WS 856 (i). 



Specific characters. A massive species having the body dorsally arched. The head 

 is rather broader than long, with two pairs of eyes between which run a pair of transverse 

 prostomial ridges separated by the median tentacle. The head is deeply incised behind. 

 The median tentacle is longer than the laterals. Tentacles and cirri are smooth. 



The dorsal cirri are extremely long and the top of the foot is provided with a small 

 languet. The two or three uppermost bristles in every foot have very long and slender 

 bidentate end-pieces. The rest of the bristles have relatively short and broad end-pieces, 

 also bidentate. The ventral cirri are broad and triangular. 



The pharynx carries in addition to a single large terminal tooth a crown of nine 

 chitinous teeth. This crown is encircled by a band of nine large papillae, behind which 

 is a second band of nine flattened, semicircular papillae. 



Remarks. This species is very fragile and all my specimens are fragmentary. 



Genus Amblyosyllis, Grube 

 Body short, composed of trapeziform segments with deep intersegmental constric- 

 tions. The palps are fused at their base. There is a pair of nuchal epaulettes. The 

 pharynx is long and coiled and armed with a circlet of teeth. The tentacles and dorsal 

 cirri are pseudo-moniliform. The penultimate segment is achaetous. 



Amblyosyllis granosa, Ehlers.

Occurrence. St. 929, New Zealand (i); WS 33 (i). 



Specific characters. From New Zealand there is a single somewhat ill-preserved 

 specimen measuring 13 mm. in length for 15 segments of which 13 are chaetigers. The 

 ground colour is pale yellow and there are here and there on the dorsum traces of what 

 was probably dark transverse striping. In addition the dorsal surface is dotted with 

 numerous small dark specks. The head is rounded and there are two pairs of large 

 orange-coloured eyes and a pair of long digitiform nuchal organs pointing outwards. 

 The palps are turned down underneath the head. The median tentacle is longer than 

 the laterals. They and the very long dorsal cirri are apparently moniliform. The ventral
