JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 295 
333. Synchiropus ijimz 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 I-5; 
eighteen or twenty pores in lateral line. 
Body but little depressed, 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 small 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 Zodlogy in the Imperial 
University of Tokyo.
