Close to Macrourus, differing in the larger terminal month. (Kopvtiaiva,

2954. CORYPHJENOIDES RUPESTRIS, Gunner. 



D. 10; P. 19; V. 7; gill rakers 4+1519. Head short, rather com- 

 pressed; snout short, obliquely truncated in front; cleft of mouth wide, 

 lateral, extending to beyond the center of eye; intermaxillary not much 

 shorter than maxillary. Teeth in villiform bands in each jaw; barbel 

 very small. Interorbital space convex, its width being considerably more 

 than diameter of eye, which, in a specimen 3 feet long, is equal to the 

 length of the snout and of that of the head. Scales equally rough over 

 the whole of their surface, all the spinelets being directed backward; 7 or 

 8 scales in a transverse series between the dorsal fin and the lateral line; 

 head entirely covered with small scales. Anterior dorsal spine armed with 

 numerous small closely set barbs ; outer ventral ray produced into a long 

 filament. Distance between the vent and isthmus the length of the head. 

 The gill membrane entirely free from the isthmus behind. Intermaxillary 

 continues beyond its vertical process and extending almost as far back 

 as the maxillary, these 2 bones being about equal in length ; last third 

 of intermaxillary toothless ; intermaxillary teeth in a very narrow band, 

 which is uniform in width, the outer teeth only slightly enlarged; man- 

 dible with villiform teeth in a broad bunch-like band at the syrnphysis 

 and becoming uniserial behind. Eye nearly circular. Snout projecting 

 slightly. Gill rakers longer and less tubercular in character than in 

 Macrourus berglax and M. acrolepis. The suborbital ridge feebly developed 

 and very abruptly curved upward and narrowed in front of the eye where 

 it joins the nasal ridge. In M. berglax and M. acrolepis the suborbital ridge 

 is very strong and is continued almost in a straight line toward the nasal 

 ridge. (Goode & Bean.) Arctic seas and the north Atlantic, on both 

 coasts south to the banks of Newfoundland and Norway, in deep water. 

 (Eu.) (rupestris, living about rocks.)

Head 6. D. II, 8-100; A. 117; V.10; eye 4 in head. Snout acute, pro- 

 jecting beyond the mouth, its tip at a distance from the mouth equal to or 

 greater than diameter of eye. Bones of head very soft and flexible, its 

 surface very irregular, there being a very prominent subocular ridge, a 

 prominent ridge extending from tip of snout to middle of interorbital 

 space, and a curved ridge extending from upper anterior margin of orbit
