78 DISCOVERY REPORTS 



Ross Sea (74° 25' S, 179° 3' E), at a depth of 296 metres. I have elsewhere given 

 reasons for following Waite in regarding these species as identical. 



The name Pogetodes was given by Richardson, without trivial name, to a fish 160 mm. 

 in total length, which was "thrown up by the spray in a gale of wind, against the bows 

 of the Terror, and frozen there", at 77° 10' S, 178^ W. The specimen was unfor- 

 tunately appropriated by the ship's cat before a description or detailed drawing could 

 be made. The rough sketch published by Richardson depicts a fish not unlike a Cryo- 

 draco, but, as Regan has pointed out, in some characters it shows more resemblance to 

 Pagetopsis. The name Pagetodes should, therefore, be eliminated. 



Cryodraco pappenheimi, Regan. 



Pagetodes antarcticus {non Dollo), Pappenheim, 1912, Deutsche Siidpol.-Exped. ,xin, Zool. v, p. 175. 

 Cryodraco pappenheimi, Regan, 1913, t.c, p. 289. 



Closely related to C. antarcticus, but length of head 2f in the length of the fish. 

 Snout \ length of head ; diameter of eye 5, interorbital width 4 in length of head. Dorsal 

 V, 45. Anal 39. Pelvics reaching fourteenth ray of dorsal (the prolonged rays perhaps 

 not entire). 



Hab. Wilhelm Land. 



The type of the species, 168 mm. in length to base of caudal, was obtained from the 

 stomach of a seal at the Winter Station of the ' Gauss'. 



Genus CHIONODRACO 



Chionodraco, Lonnberg, 1906, K. Svensk. Vet.-Akad. Handl., xl (5), p. 99; Regan, 1913, t.c, 

 p. 288; 1914, Rep. Brit. Antarct. {'Terra Nova') Exped. 1910, Zool. i (i), p. 12. Type 

 Chaenichthys rhinoceratus hamatus, Lonnberg. 

 Body naked, elongate; three lateral lines, without bony plates. A rostral spine; eye 

 somewhat behind middle of head ; supraorbital ridges crenulated. Teeth bi- or tri-serial ; 

 gill-rakers absent except for a few vestiges near the angles of the arches ; operculum 

 with a group of 3 to 5 spines, the uppermost with 2 to 4 points ; sub- and inter-oper- 

 culum bearing a pair of spines just behind angle of praeoperculum. Spinous dorsal 

 well-developed, of five to seven spines ; pelvics comparatively short, of a spine and five 

 branched or bifid rays, the two outer the longest and (in adult) enveloped in thick 

 skin. Skeleton essentially similar to that of Champsocephaliis. Vertebrae 64. 

 Two species. 

 Coasts of the Antarctic Continent.
