174 DISCOVERY REPORTS 



Genus Amage, Malmgren 



Body rather stout. Prostomium clearly trilobate, with raised glandular ridges. 

 Tentacles smooth. Branchiae three to four pairs. Nopaleae. First and second notopods 

 sometimes reduced. Dorsal cirri present in the thoracic region and both dorsal and 

 neuropodial cirri in the abdominal region. Uncini begin on 4th chaetiger. 



Amage sculpta, Ehlers. 



Ehlers, 1908, p. 141, pi. xx, figs. 1-9. 

 Hessle, 1917, p. 121. 

 Monro, 1930, p. 180. 



Occurrence. St. 182 (i); 366 (3). 



Specific characters. These specimens are in poor condition. Body thick and slug- 

 like, sharply tapered posteriorly. Up to about 30 mm. in length by 6 mm. at the widest 

 part. The gills are not fused basally and the two groups of four gills are clearly separated. 

 There are 14 pairs of thoracic notopods, of which the first two pairs have the bristles 

 more or less inclosed within the notopodial lobes. There are 10 pairs of abdominal 

 neuropods. The dorsal cirri are well developed, especially in the abdominal region where 

 they are clavate. Small neuropodial cirri are also present in the hinder region. The 

 bristles are bordered capillaries. The hooks have usually four teeth in profile, all the 

 teeth being single except those of the third row which are double or paired. One of the 

 specimens from St. 366 shows five teeth in profile with paired teeth in the fourth row. 

 There appears to be a pair of short dorsal anal cirri. 



Genus Phyllocomus, Grube 



Prostomium rounded, -not distinctly trilobate. No raised glandular bands. Tentacles 

 smooth. Four pairs of gills. No paleae. Dorsal cirri present in thoracic region and 

 both dorsal and neuropodial cirri in the abdominal region. No reduction of the notopods 

 in the first two chaetigers. Anus surrounded by a circlet of large papillae or cirri. 



Phyllocomus crocea, Grube. 



Mcintosh, 1885, p. 427, pi. xlvii, fig. 11; pi. xxvIa, fig. 25; pi. xxxviiA, fig. 6. 



Hessle, 1917, p. 123. 



Monro, 1930, p. 181, fig. 75 a-c. 



Augener, 1932A, p. 82, fig. 10 a, b. 



Occurrence. St. 363 (4); 371 (2); WS 877 (i). 



Specific characters. Up to 83 mm. in length. The cephalic lobe is rounded and not 

 distinctly trilobate. It is usually splashed with dark red pigment. There is a pair of 

 crescentic nuchal organs. There are four pairs of gills. The two outer pairs consist of a 

 rounded central axis on each side of which is a membrane. The two inner pairs have 

 four membranes coming off" from the central axis. There is considerable variation in the 

 width of the branchial membranes especially in the outermost pair of gills. There are 

 15 pairs of thoracic notopods and about 45 pairs of abdominal neuropods. Dorsal cirri 

 are well developed in the anterior abdominal region, but decrease in size posteriorly.
