Iracundus signifer, Jordan & Evermann, new species. 
Head 2.4 in length; depth 3.2; eye 4 in head; maxillary 2; D. x, i, 9; A. in, 5; P. 17; V. i, 5; 
scales about 9-55-30, about 45 pores. 
Body rather elongate, moderately compressed, the head conic, not depressed; mouth large, 
oblique, the lower jaw slightly projecting, the maxillary reaching to opposite posterior margin of 
pupil; teeth in moderate bands in the jaws, the inner teeth in the upper jaw slightly largest; vomer 
with small teeth; palatines toothless; interorbital area deeply concave, little wider than pupil; spines 
on top of head low and rather sharp, much as in Sebastodcs; preocular, supraocular, postocular, tym- 
panic, occipital, and nuchal spines present; a ridge with 2 spines outside the tympanic spine; preor- 
bital moderate, about as wide as eye, with a sharp spine turned forward and a blunt spine turned 
backward; suborbital stay a narrow, simple ridge, reaching base of preopercular spine, which is 
straight and very short; 3 lower preopercular spines reduced to blunt points; opercle with 2 slender 
diverging spines, the upper the larger, their points not reaching edge of membrane; head with numer- 
ous, broad, fleshy flaps; a fringed flap at the nostril, 2 on edge of preorbital, 2 on lower limb of 
preopercle, and a high fringed flap above eye, about as long as pupil; small simple flaps on the cheek, 
the end of the maxillary, and elsewhere on head; large pores on lower jaw, under suborbital stay, and 
elsewhere; opercle and upper part of cheek with rudimentary, embedded scales; jaws naked; top of 
head scaleless, occiput covered with thin skin and scarcely depressed; gillrakers very short, thickish, 
and feeble, all but about six reduced to mere rudiments; no slit behind last gill; body covered with 
small, close-set scales, which are slightly ctenoid; scales on nape small, on breast minute; lateral line 
conspicuous, provided with dermal flaps; numerous scattered flaps on sides of body. 
Dorsal fin very deeply notched, the spines rather slender, pungent, the first a little longer than 
eye, the second and third subequal, about half longer, the fourth greatly elevated, 1.5 in head, almost 
twice height of third and fifth, which are subequal; sixth, seventh, and eighth slightly longer than 
fifth, tenth very short, eleventh half length of fourth; soft dorsal high, the longest rays nearly half 
head; rays of all the fins scaleless; caudal long, rounded, 1.4 in head; anal high, the spines graduated, 
the third a little longer than second, which is 2.6 in head; longest soft rays 1.8 in head; pectoral with 
the rays all simple, the longest 1.2 in head, lowest rays shortened and thickened; ventral fins inserted 
below axis of pectoral, rather long, 1.6 in head, not. quite reaching anal, inner rays well free. 
Color, pale in alcohol, doubtless vermilion red in life, the flaps on body pinkish; a single jet-black- 
spot about half diameter of pupil near tip of membrane between second and third spines of dorsal. 
The only example known is the type, No. 50886, U. S. N. M. (field No. 635), a specimen 4.2 inches 
long, taken by us on the coral reef at Honolulu.
