line. Anterior margin of the second dorsal spine armed with 

 barbs placed at some distance from each other. The second 

 dorsal fin commences at a distance behind the first scarcely 

 inferior to the length of the base of the first. The outer ven- 

 tral ray produced into a long filament. 



Pacific, north of Kermadec Island (Stations 170, 171) 

 500-650 fathoms. 



Coryphcenoides cequalis. 



Snout conically projecting beyond the mouth, with rather 

 obtuse upper edge ; the cleft of the mouth extends nearly to 

 below the centre of the eye. The teeth of the outer series are 

 visibly stronger than the remainder. Barbel slender, but not 

 so long as the eye. The interorbital space is flat, its width 

 being considerably less than the diameter of the eye. The 

 scales are equally rough over the whole of their surface, the 

 spinelets being subequal in size, densely packed, but arranged 

 in from 8 to 12 series, the middle series not being more pro- 

 minent than the others (as is the case in Macrurus sclerorhyn- 

 chus). The entire margin of the scale is spinous. There are 

 eight scales in a transverse series between the first dorsal and 

 the lateral line. Second dorsal spine somewhat produced, 

 armed along its anterior edge with barbs pointing upwards 

 and rather closely set. The second dorsal fin commences at a 

 distance from the first which is less than the length of the 

 head. 



Deep-sea, south of Portugal, 600 fathoms. 



Coryphcenoides crassiceps. 



Head very large, especially the anterior portion. Snout 

 excessively broad and high, short, but longer than the eye, 

 which is small. Mouth small, inferior, extending beyond tlie 

 vertical from the centre of the eye. Teeth villiform, in nar- 

 row bands in both jaws. Barbel minute. Trunk of the body 

 very short, the vent being immediately behind the vertical 

 from the root of the pectoral. The scales are small, studded 

 with very fine curved spinelets, which give the body the ap- 

 pearance of being covered with short villosities. A series of 

 larger scales runs along each side of the base of the second 

 dorsal fin. The second dorsal spine is very slender, obsoletely 

 denticulated in front ; the second dorsal fin commences at a 

 very short distance behind the first. 



North of Kermadec Island (Stations 170, 171), 520 and 

 650 fathoms. 



Rem. This fish is closely allied to, and represents in the 

 southern hemisphere, C. norvegicus.
