only by a single long rostral spine, the basal element of which is procum- 

 bent and subcutaneous; the extremity with numerous long filaments. 

 Soft dorsal short, with 9 rays; anal short; pectoral rather broad, with 12 

 rays. Greenland, (ijudg, a thong; Xocpoc,, crest.) 



3114. HIMANTOLOPHUS GRCENLANDICUS, Reinhardt. 



Depth 2 in total length. D. 1-9; P. 12. Body oblong oval. Cephalic 

 ray provided with about 11 tentacles. (Gill.) Greenland. u This species 

 has never been fully described, the only existing example being an imper- 

 fect one, 23 inches long, obtained off the coast of Greenland, about 1837. " 



Himantolophus grcenlandicus, REINHARDT, Dansk. Vid. Selsk. Nat. Math. Afh. 1837, 74, 

 Greenland; GILL, Proc. U. S. Nat. Mus. 1878, 218; JORDAN & GILBERT, Synopsis, 849, 

 1883. 



1068. CORYNOLOPHUS, Gill. 



Corynolophus, GILL, Proc. U. S. Nat. Mus. 1878, 219 (reinhardti). 



This genus is scarcely distinct * from Himantolophus, differing in the 

 short oval form, the short dorsal of about 5 rays, and the broader pectoral 

 with about 17 rays each, (nopvvr}, club; Ad0o, crest.) 



8115. CORYNOLOPHUS REINHARDTI (Liitken). 



Depth 1. D. 1-5 ; P. 17. Body short, oval ; cephalic ray $- length of 

 head, with about 8 tentacles, which branch out forming a brush at tip; 

 skin sparsely covered with thorn-like prickles. Greenland. One speci- 

 men known, 14 inches long. (Named for Prof. Johann Reinhardt, natu- 

 ralist at the University of Copenhagen.)

1069. LIOCETUS, Gunther. 



Lioeetus, GUNTHER, Challenger Report, xx^, 57. 1887 (murrayi). 



Mouth enormous, the cleft nearly vertical ; pectorals small, in advance 

 of dorsal and of gill opening; second dorsal spine wanting; gills in 2 

 pairs ; no gular tentacle. This genus is similar to Melanocetus, differing 

 in having no teeth on the vomer, a greater projection of the mandible, 

 and a smaller mouth. Deep sea. (Xslog, smooth; HfjTos, whale.) 



3116. LIOCETUS MURRAYI (Gunther). 



D. 1-13 ; i. 4 ; C. 9 ; P. 14. (Giinther. ) Extremely similar to Melanocetus 

 johnsonii, but without trace of vomerine teeth, while there is no distinc- 

 tion between the two species as regards dentition of jaws; posterior angle 



*Dr. Gill, replying to certain strictures as to the validity of this genus, made by Liit- 

 ken [who calls it a "wanton ' subdivision], states that the "differences alleged to exist 

 between Himantolophus and Corynolophus are very marked. If they do exist as stated 

 there can be no doubt that the two should be kept apart. I know of no reason except the 

 singularity and greatness of the difference specified for doubting the correctness of Rein- 

 hardt's observations."
