of mandible projecting more and forming a salient point; mouth compara- 

 tively less wide, and the maxillary considerably shorter, being about \ of 

 total length, without caudal, while it is rather more than \ in the Madeiran 

 species. Eye rudimentary. One cejihalic spine, shorter than maxillary ; 

 last dorsal ray connected by a short and delicate membrane with caudal 

 fin ; most of the caudal rays bifid, the longest shorter than maxillary ; 

 pectoral fin as much developed as in Mela)iocetiis johnsonil. Entirely black. 

 Total length 44 lines; length of mandible 14 lines; length of maxillary 12 

 lines; length of caudal fin lOi^ lines. A young individual, 44 lines in 

 length, was taken liy H. M. S. Challenger in the mid- Atlantic, at a depth of 

 1,850 fathoms (Station 106); another of 13 lines at the depth of 2,450 

 fathoms (Station 348). (Goode &, Bean.) (Named for Dr. John Murray, 

 second director of the civilian staff on board H. M. S. Challenger. )

Linophryne, Collftt, Proc. Zool. Soc. London 1886, 138 (Lucifer). 



Head enormous; the body slender, compressed, mouth oblique. Spinous 

 dorsal reduced to a single cephalic tentacle, the basal part of which is 

 erect, not procumbent. Teeth in the jaws on the vomer and the upper 

 pharyngeals. Gill openings exceedingly narrow, situated a little below 

 the root of the pectoral. Soft dorsal and anal very short; ventrals none. 

 Abdominal cavity forming a sac, suspended from the trunk. Skin smooth ; 

 a long tentacle on the throat. This genus differs from Melanocetus in the 

 presence of the gular tentacle. (AzVoj, linen, net; <l>pvvrj, a toad.)

D. 1-3; A. 2; C. 9; P. 14 or 15. A spinous projection or horn above 

 each orbit. Cephiilic tentacle black, with a large ovate bulb, the upper
