Head (to end of bony operculum) 3 in length; depth 2.5; pectoral 2.25; ventral 3; caudal 3.2; 
1). xiii, 9; A. in, 5; C. 19; F. 18; Y. i, 5; scales 8-38-13. Head and body much compressed, greatest ; 
width through bases of pectorals, 5 in length, 2 in greatest depth; dorsal profile a little more convex j 
than ventral, greatest depth at vertical through base of fifth spine; eye oval, longest diameter hori- ! 
zontal, 3 in head; interorbital deeply concave, 2 in horizontal diameter of eye; profile of snout almost 
straight, inclined at angle of 45°; length of snout ecpial to vertical diameter of eye; suborbital 5 in 
head; maxillary reaching to posterior margin of pupil, 2 in head; tip of upper jaw with a toothless depres- 
sion between inner ends of premaxillaries which receives a slight knob on the upper surface of the 
symphysis of the lower jaw ; teeth very fine, in bands in jaws, in reniform patch on vomer; no palatine 
teeth; posterior nostril large, simple, round, close to rim of orbit; anterior nostrils smaller, each with, 
flat tentacle on posterior margin; spines on head all small, a small movable spine at outer corner of 
each posterior nostril; several small spines on upper margin of orbit, unsymmetrical on the 2 sides;

no occipital depression; 2 spines on occiput just back of eyes on each side, 2 others on each side of 
nape; a horizontal series of temporal spines; a moderately long spine at angle of preopercle, 2 smaller 
ones below it; a flat spine at angle of opercle; suborbital stay with a series of several very inconspicuous jj 
spines reaching from below anterior margin of orbit to angle of preopercle; a small pit below 7 anterior 
lower angle of eye; opercle and preopercle scaled, other parts of head naked; branchiostegals 7; 
gillrakers 6 -j- 10; fin rays not excessively developed; dorsal fin beginning above middle of opercle; 
fourth to eighth spines longest, 1.5 in head; first spine 2.75 in head; twelfth shortest, three-fifths of first, 
2.5 in fourth; thirteenth spine longer, equal to first and to eleventh; soft dorsal short; median rays 
longest, but slightly shorter than longest spine; last soft ray equal to last spine; caudal slightly rounded, i 
median rays 1.25 in head, 3 uppermost and 3 loivermost rays short and spine-like; first anal spine 
shortest and slender, 3.6 in head, a little longer than twelfth dorsal spine; second and third spines of 
equal length, but second much thicker than third, each 1.5 in longest dorsal spine, a little less than half 
of head ; longest pectoral rays reaching to posterior end of base of anal fin ; fourth to seventh rays, from 
above, longest, a little less than half of length of- body; uppermost ray equal to third dorsal spine;
