NOTES OX SOME JAPANESE FISHES. 19 



a (.listinct genus. I propose to call the subgenus by the name of 

 Paraceratlas. It is characterized as follows : 



Two tentacles, one above eye and the other on back ; o 

 dorsal caruneles perforated at tip ; gill-openings much nearer to 

 tip of snout than to caudal base ; gills 2i ; no ventrals ; skin 

 very finely prickled. 



The description of the new species is as follows : 



Length of head 2:' in total length without caudal, height 

 of body at base of pectoral 2^ ; snout 2i in head, eye 2ùl, 

 length of maxillary 2i ; width of gill-opening 4.1, length of 

 cephalic tentacle li, dorsal tentacle 2y. 



Body oblong, compressed ; candal peduncle also compressed ; 

 body highest at base of pectoral, more strongly tapering posteriorly 

 than anteriorly. Head large, a little less than one half total 

 length without caudal ; eye very small, nearer to tip of snout than 

 to gill-opening. Nostril one on each side of head, tubular, near 

 tip of snout. Mouth subvertical, not very large ; lower jaw 

 included, its symphysis provided with a prominently protruding 

 spinous tip ; mandibular teeth anteriorly in 2 ill-defined series, 

 posteriorly in one row ; the inner series long and fang-like ; 

 all depressible. Premaxillary teeth smaller, in two or three 

 series, the largest teeth located anteriorly ; vomer with some fang- 

 like teeth on the side of its head, the tip having no teeth ; 

 palatines almost without teeth. Tongue toothless. Gill-openings 

 rather narrow, just below pectoral, partly extending around the 

 base of the fin, the course of openings directed downward and 

 forward. Gills 2h ; gill arches nearly smooth ; no pseudo- 

 branchiae. Pectoral small, inserted nearer back than belly ; no 

 ventral. Distance from caudal base to vent contained 21 times 

 in the length from vent to tip of snout. Cephalic tentacle
