GLYCERIDAE i43 



In the anterior region the feet are uniramous and the change over to the biramous 

 condition takes place at the 59th chaetiger. In front the feet (Figs. 25 c, d) increase in 

 size with the widening of the body from before backwards. They comprise a large, 

 flattened somewhat curved dorsal cirrus with a distinct border on its upper surface, a 

 pedal lobe with two digitiform lips in front and a single triangular lip behind, and a 

 ventral cirrus rather like the dorsal except that it is inserted farther forward on the foot. 

 In addition to an increase in size from before backwards in the anterior region there is a 

 tendency for the two anterior lips of the chaetal lobe to fuse proximally. Behind the 

 59th chaetiger in the biramous region there is a broad, flattened, dorsal cirrus and a 

 triangular dorsal ramus of about the same size : in the ventral ramus the two anterior 

 lips are fused proximally, only their pointed ends remaining free, and the posterior lip 

 is a broad flattened structure resembling a tennis-racquet in shape with a small tri- 

 angular process at the apex: below the ventral ramus there is a broad, flattened ventral 

 cirrus (Fig. 25 ej). 



There is very little change in the shape of the feet throughout the body behind the 

 59th chaetiger except in the hindmost region, where the body begins to narrow and the 

 feet become smaller. Here the upper of the two anterior lips of the ventral ramus in- 

 creases in size relatively to the lower (Fig. 25^). Otherwise there is no change. 



In regard to the bristles, those of the ventral ramus are long compound bristles with 

 faintly denticulated end-pieces (Fig. 25 //). The dorsal ramus is supported by an 

 aciculum and carries a bundle of simple capillary bristles (Fig. 257) almost entirely en- 

 closed within the dorsal ramus. Only their ends are free of the chaeta-sac and they are 

 almost wholly hidden by the triangular anterior lip of the dorsal lobe. 



Remarks. This species is a Goniada in everything except the possession of chevrons 

 on the proboscis, and according to Ehlers chevrons are present in young specimens, but 

 disappear in the adult. It is distinguished from other species by its size and by the great 

 length of the anterior uniramous region. It seems to be more closely related to G. 

 longicirrata, Arwidsson, than to any other species, but is distinguished by differences in 

 the dorsal bristles and by the structure of the jaws. 



Genus Glycinde, Mijller 



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

 region with biramous feet. The proboscis is long and clavate, and covered with papillae. 

 There is a pair of large, toothed jaw-plates and a circlet of small paragnaths. There are 

 no V-shaped chevrons on the proboscis. The dorsal bristles are acicular and plumed 

 and the ventral bristles are compound spinigers. There are no branchiae.
