CALLIONYMUS BENITEGURI Jordan and Snyder, new species. 

 (Plate XVII. ) 



A tkillionyinuii which wc are unable to identify with any known 

 species differs markedly from 61 curvicornis and C japonlcus in 

 having- a less pointed snout and a much wider interorbital space. We 

 here describe it as CaUionymus henltegur!^ new species. 



TijjJe.—^o. 49402, U.S.N.M. From Bay of Tokyo, Japan. C'ol- 

 lected by K. Otaki. 



Description. — Head, 3| in bod}^; depth, 2^ in head; snout, 2i; orbit, 

 4|; interorbital space, 9^, maxillary, 2f ; first dorsal spine, 2i; ray, 1^; 

 last dorsal ray, 4f in bod}"; first anal ray, 10^; last anal ra}", 6i; length 

 of pectoral, 5; ventral, 4^; caudal, 2|; number of dorsal spines, 4; 

 rays, 9; anal rays, 9; pectoral rays, 20. 



Body much depressed; snout, viewed from the side, acute; from 

 above, sharplj^ rounded. Upper rim of orbit projecting- above dorsal 

 contour of head; interorbital space deeply convex. Eye nearer gill- 

 opening than tip of snout, a distance equal to its longitudinal diameter. 

 Upper jaw projecting a little beyond the lower, maxillary excessively 

 protractile, its posterior end falling short of a perpendicular through 

 anterior edge of orbit, a distance equal to intororl)ital space. I^ips 

 extending laterall}' as flaps, which unite on each side Ijclow the middle 

 of maxillary. Teeth of jaws in narrow villiform bands. Distance 

 between gill-openings equal to length of snout; width of spiracle 

 equal to one-half the diameter of eye. Preopercular spine prominent; 

 posterior end with three large teeth, the first projecting backward; 

 the third projecting upward; a minute tooth proximal to the third; 

 basal part of spine with a tooth equal in size to the first, which pro- 

 jects forward; all the teeth covered with skin, so that only their tips 

 project. Lateral lines extending, one on each side of body and on 

 caudal fin; connected hy a loop over posterior part of caudal peduncle,
