29. D. iv-9, none of the spines produced, the last ray cleft to base; A. 8, the last ray cleft to base; Y. i, 
5, the rays profusely branched, the membrane joining the pectoral fin a little above its middle; P. 18. 
Form depressed anteriorly, wider than deep; occiput nearly flat; a slight prominence on each side 
median line, minutely rugose; bony interorbital space very narrow, less than half diameter of pupil, 
and not grooved; snout very narrow and sharp, longer than diameter of orbit; mouth horizontal, 
maxillary not reaching vertical from front of orbit; preopercular spine robust, straight, its tip reaching 
slightly beyond opercular margin, its inner edge with 6 or 7 strong slender curved spinelets, evenly 
and closely spaced, decreasing in length toward base of spine, the terminal one shorter than the one 
before it, but curved in the same direction; outer edge of spine smooth, but bearing a short retrorse 
spine near its base; gill-opening a minute pore superiorly placed. 
None of the dorsal spines produced or filamentous in the type, a female; first spine longest, reaching, 
when declined, to base of second soft dorsal ray; second dorsal and anal fins beginning at the same 
vertical; caudal rounded; pectorals reaching well beyond ventrals, the latter slightly passing vent. 
Ground color greenish olive above, silvery white on abdomen and throat; upper parts of head and 
body profusely marked with reddish gilt in stripes and patches which almost wholly conceal the ground 
color; in addition there are many minute round spots of coral-red, covering upper part of snout, 
.interorbital space with upper part of eyeballs, upper half of opercles, and the preopercular spine; a line 
of them bounds the occiput, and a few occupy the upper part of cheek; they form an inconspicuous 
cross-bar below spinous dorsal and 2 below soft dorsal; they occupy also the membrane between first 
and second dorsal spines, and a few are found on the distal half of ventrals and the median caudal 
rays; pectorals largely translucent; ventrals with a broad black bar at base and one at tip; membranes 
of spinous dorsal largely dusky, soft dorsal translucent, with 6 oblique olive-brown bars on tips of last 
rays, the last one blackish; anal translucent, the last rays tipped with black; caudal with 3 broad olive- 
brown bars, as wide as the translucent interspaces; iris silvery, tinged with red. 
Only the type known. 
Callionymus rubrovinctus, new species. Fig. 252. 
Type, 24 mm. long, from station 3876, channel between Maui and Lanai islands, depth 28 to 43 
fathoms; type, No. 51580, U. S. Nat. Mus. 
Head (measured to opercular edge) 34 hundredths of total length without caudal; greatest width 
23; depth 16; eye 12, much longer than snout. D. iv-8; A. 8; P. 17. 
Comparatively very short and heavy; snout very short, not more than two-thirds diameter of eye; 
mouth much more oblique than usual in the genus, maxillary reaching a little past front of eye; inter- 
orbital space very narrow, minutely grooved; occiput broad, transversely rounded, minutely roughened 
by anastomosing lines and points; preopercular spine very long and robust, projecting beyond opercular 
margin, its tip curved upward to form a slender hook, immediately anterior to which on the upper 
margin are two stronger hooked spines, the posterior directed upward, the anterior upward and for- 
ward; lower edge of preopercular spine smooth; the antrorse denticle at base on outer face of pre- 
opercular spine, usually present in species of Callionymus , is here wanting; branchial pore occupying 
its usual position, immediately below origin of lateral line.
