Genus Glycera, Savigny 

 Body rounded and tapered at both ends. The segments are bi- or triannulate. Head 

 sharply conical, ringed, ending in four small tentacles. Proboscis clavate with four 

 hooked jaw-plates. Feet biramous with minute dorsal cirri. The pedal lobes have two 

 anterior and one or two posterior lips. There is a large ventral cirrus. Branchiae may 

 be present or absent; they may be simple or branched, retractile or not retractile. 

 Dorsal chaetae simple capillaries, ventral chaetae compound spinigers.

 Monro, 1930, p. 115. 



Occurrence. St. 123 (i); 144 (3); 175 (i); WS 90 (i); WS 228 (3); WS 246 (i). 



Specific characters. A slender species up to about 60 mm. in length. The body- 

 segments are three ringed. Head with about eight rings. Papillae of proboscis of two 

 kinds, the more numerous long and cylindrical, the rest short and ovoid. The feet are 

 short with two anterior lips and a single posterior. The anterior lips are conical and the 

 upper is a little shorter than the lower. The posterior lip is short, broad and rounded. 

 The dorsal cirrus is a small globular process set very high up above the foot. The ventral 

 cirrus is broad and conical. There are no branchiae. 



Genus Goniada, Audouin and Milne-Edwards 

 Body divided into two regions, an anterior region with uniramous feet and a posterior 

 with biramous feet. The proboscis is papillated ; and there is a pair of large toothed jaw- 

 plates and a circlet of small paragnaths. In addition on each side of the base of the 

 proboscis there is a longitudinal row of V-shaped paragnaths (chevrons). These are 

 sometimes absent in adult specimens. There are no branchiae. The dorsal bristles are 

 capillary and the ventral compound. 



Goniada eximia, Ehlers (Fig. 25 a-j). 

 Ehlers, 1901, p. 157, pi. xx, figs. 7-17. 



Occurrence. Stanley Harbour, Falkland Islands between tide-marks (i). 



Specific characters. The single specimen is a gigantic glycerid measuring 76 cm. 

 by 1-3 cm. without the feet at the widest part for 258 chaetigers. Some of the hindmost 

 segments are missing. The colour in spirit is yellowish green. The body is somewhat 

 flattened dorso-ventrally and tapered at each end, the tapering in front being much 

 more pronounced than that of the hinder region. The head is extremely small for the 

 size of the animal, measuring only 4 mm. in length. It is rather blunt, composed of 

 about eight rings and ends in the usual four small tentacles. I see no eyes. The pro- 

 boscis is partly extruded and is densely covered with small papillae, not arranged in
