JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 295 



333. Synchiropus ijimae sp. nov. (Plate XXXVI, fig. 1). 



The type described, No. 6015a Carnegie Museum Cat. of Fishes, is a specimen 

 which came from Misaki and is sixty-five millimeters in total length. 



Head 3.16 in length to base of caudal; depth 5; eye 4 in head; snout 3.66; width 

 of body at opercles 1.5 in head, 1.16 times in depth; D. IV-8; A. 7; P. 18; V 1-5; 

 eighteen or twenty pores in lateral line. 



Body but little depres.sed, nearly as deep as wide at head, more so posteriorly; 

 its form quite unlike that of the Japanese species of Callionymus; eyes large, ob- 

 liquely set, projecting above profile of head; bone of interorbital space very narrow, 

 3.33 in pupil of eye; suborbital space 6.5 in head; maxillary reaching anterior edge 

 of eye; pre-opercular spine with two hooks, one at its tip, and another, as strong 

 above; gill-opening circular, small, at upper angle of opercle; latter with a loose, 

 fold of skin below forming a flap-like lower edge above ventrals, this not free at 

 tip of opercle; teeth of both narrow jaws anteriorly in broad bands, which poster- 

 iorly diminish in breadth. 



Insertion of spinous dorsal over point of pre-opercular spine ; all its rays filiform, 

 membrane extending along three-fifths of first spine, one-half of third spine and 

 two-fifths of fourth spine; first spine slightly longer than head, second somewhat 

 longer, 2.5 in head; second dorsal of equal height save for last somewhat elongate 

 rays; anterior rays 1.6 in head; last ray reaching to base of upper rudimentary 

 caudal rays, as does last of anal; caudal rounded; anal rays 2 in head, insertion 

 below first and second rays of soft dorsal; pectoral reaching beyond anal insertion; 

 ventrals of like extent, their bases in large part anterior to those of pectorals; 

 membrane from inner ray attached to middle of pectoral base. 



Color in alcohol light, with brown spots arranged across body in seven bands 

 as wide as eye, these bands tending to coalesce extensively on lower side of flanks 

 before being lost in colorless lower surface of body; cheeks and suborbitals with 

 similar or slightly smaller brown spots more clearly defined than those of body; 

 a brown blotch as large as pupil below pre-opercular spine; spinous dorsal with 

 narrow sinuous streaks and shadings of brown; soft dorsal broadly banded with 

 brown; bands running downward and backward to base of fin as they pass backward; 

 membrane between last rays dark brown; caudal with four or five cross-bands, plain- 

 est on upper and lower rays; pectoral with five or six brown cross-bands; ventrals 

 with inner rays dark brown at tip; body indefinitely clouded elsewhere, with a 

 number of smaU clear spots on membrane connecting with mid-pectoral base; anal 

 rays tipped with white, their membranes darkened in margin. 



This species is named for Mr. Isao Ijima, Professor of Zoology in the Imperial 

 University of Tokyo.
