crossbands; a brown band in front of base of pectoral extending on lower pectoral rays; ventral with 
dusky blotch at base, outer portion with about 5 dusky crossbands. 
'I lie only example we have seen of this species is the type, No. 50650, I . S. N. M. (field No. 05030), 
6 inches long, obtained by us at Honolulu.

Head 2.5 in length; depth 2.5; eye 3.4 in head; snout 3.3; interorbital 5; maxillary 2.1; mandible 
1.8; D. xin, 10; A. hi, 6; I*. 18; V. I, 5; scales 8-52-13. 
Body elongate, compressed, rather deep, the greatest depth at fifth dorsal spine; profiles of trunk 
above and below more or less even; head compressed; snout short, rounded; mouth large, maxillary 
nearly reaching below middle of eye, its distal expanded extremity equal to half eye; minute teeth in 
bands in jaws and on vomer; lips thin; tongue pointed, compressed, free in front; jaws nearly equal; 
anterior nostrils each with a small fleshy flap; interorbital space deeply concave; fifth dorsal spine 
longest, 1.25 in head; penultimate spine 5.2; second anal spine longest, 2.1; third anal ray longest 1.3; 
caudal rounded, 1.25; pectoral 2.4 in trunk, reaching below middle of base of soft dorsal, rounded, and 
only membranes between lower rays slightly incised; ventral rounded, reaching base of first anal ray, 
caudal peduncle compressed, its least depth 3.5 in head; nasal spines very small, preocular, postocular; 
tympanic and coronal spines present; parietal and nuchal spines forming a single ridge; a ridge of 
spines behind eye above operole; a ridge of spines below eye, ending in a spine on margin of preopercle; 
2 spines below this also on margin of preopercle; no opercular spines; margin of preopercle with spine 
projecting down and hack; skinny flap" above eye equal to its diameter, and another from preorbital 
spine; scales small, ctenoid; head naked except some scales on operele, cheek, and side above; lateral 
line running obliquely down to base of caudal. 
Color in alcohol, pale brown or whitish; side with 3 pairs of deep brown vertical bands, first on 
posterior part of head preceded by a deep brown streak from below eye, second on middle and posterior 
part of spinous dorsal, and third extending out on soft anal and basal portion of soft dorsal; soft dorsal, 
caudal, and anal pale or whitish; membranes of dorsal spines deeply incised in front, each spine with 
3 brown crossbands; pectoral grayish with a blackish brown basal blotch and 5 blackish crossbands; 
ventral blackish with 2 whitish or grayish blotches. 
The nominal species, 1). hudsoni, is especially characterized by the unspotted soft dorsal, anal, and 
caudal. It was thought to be distinguished from Dendrochirm barberi Steindachner by the longer pec¬ 
toral, which reaches to below the posterior dorsal rays, but this character is found not to be.constant. 
We have 1 specimen, 1.8 inches long, from Waikiki, and 4 others, 2 collected by us and 2 bv 
Jenkins, all at Honolulu, and ranging from 1.8 to 4 inches long. The Albatross also obtained speci¬ 
mens at Honolulu.
