EEPOET ON THE DEEP-SEA FISHES. 67 



anterior half of the head and one-fifth of its length. Nostrils not tubulated. Cleft of 

 the mouth not extending to the front margin of the eye. Teeth simple, unicuspid. 



Vertical fins continuous, caudal very narrow and pointed. The origin of the anal is 

 opposite to the eighth dorsal ray. Form of the pectoral typical, the foremost rays being 

 opposite to the anterior margin of the venti'al disc. Ventral disc circular, small, one- 

 fourth of the length of the head, situated immediately Ijehind the level of tlie eye. Vent 

 very close to ventral disc. Colour light greyish or purplish. 



Habitat.—" Knight Errant," 1882, Station 9 ; depth, 608 fathoms. Two specimens, 

 2 and 3^ inches long. 



" Knight Errant," 1880, Station 8 ; depth, 540 fathoms. One specimen, 3^ inches long. 



A specimen obtained on the cruise of the "Porcupine" in 180 fathoms, north of 

 Shetland, was referred by me to Liparis liparis, to which it probably belongs ; it is, 

 however, in too bad a state of preservation to be identified with certainty.

Tail very long and attenuated. Ventral disk very small, scarcely larger than the 

 eye, immediately below the front part of which it is placed. Pectorals deeply notched, 

 extending forwards to the mandibulary symphysis. Vent close to the disk. Skin 

 glutinous ; body semitransparent. Abdominal cavity black. 



An Arctic circumpolar species, fir.st described from the North Pacific (Behring's Strait), 

 afterwards found on the Greenland coast, and recently discovered by the North Atlantic 

 Expedition about Jan Mayenand Bear Island, and off Arendal, at depths varying between 

 263 and 658 fathoms; also found in the Kara Sea. 



' This work has been referred to by Collett in a somewhat singular manner. As no specimen of Liparis gelatinosus 

 was in the British Museum at the time of the publication of the third volume of the Catalogue, a literal translation 

 ot Pallas and Steller's account was given, and stated to be such. Yet Collett quotes the translation with the addition 

 of a 1 rather than the original authors ! Jordan also adds a mark of interrogation to his quotation of the Catalogue, 

 but this must have been an oversight, as his diagnosis is shaped after the one given in that work.
