482 BULLETIN OF THE UNITED STATES FISH COMMISSION. 
gill-opening long and oblique, the lower arm extending far forward, the upper end on a level with 
lower edge of orbit and directly above upper base of pectoral; interorbital space moderately broad, 
the 2 sides meeting at a broad, rounded angle; entire body and head finely granulated or velvety; each 
side of caudal peduncle with two, weak, keeled, horny plates, the distance between which is 1.4 in eye; 
first dorsal spine strong, roughened laterally, inserted above gill-opening; other dorsal spines slender, 
smooth, and pointed, the third longest, its length nearly equaling that of snout; dorsal rays slender 
and weak, shorter than the spines, the longest about 2.8 in head; anal spines slender and pointed, the 
second slightly the longer, its length equaling diameter of eye; anal similar to soft dorsal, but some- 
what lower; caudal deeply lunate, the lobes not greatly produced, the upper slightly the longer; 
ventral spines long, rather strong, reaching base of second anal spine, their length equaling that of 
longest dorsal spine; pectoral of moderatelength, 1.4 in head. 
Color in alcohol, nearly uniform olivaceous brown; pale below; dorsal fin darker brown, crossed 
by 3 broad, longitudinal lighter bands; on the spinous portion the lighter and darker markings are 
broken up into more or less vertical bars; membrane between first and second dorsal spines with a 
pale or transparent area distally, edge of fin narrowly black; anal similar to dorsal, but with less 
distinct bands; caudal uniform dusky; pectoral dusky, paler at tip; ventral dusky. 
Only 2 examples of this species were obtained by me and none has been secured by any subsequent 
collector. Type, No. 50706 U. S. N. M. (field No. 268), 9.25 inches long, obtained at Honolulu; 
cotype, No. 7727, L. S. Jr. Univ. Mus. (field No. 461), 9.5 inches long, from same place. 
Family XU. BAL1STID4E. 
195. Balistes vidua Solander. “ Humv.humu hinkole.” 
Color in life, uniformly dark brown with tinge of olive; membrane of spinous dorsal olive; soli 
dorsal and anal white, with a narrow black border along anterior and distal margins; distal portion 
of caudal peduncle white, fin red, the upper and lower margins 'each with a narrow black line; 
pectoral rays bright yellow; faint violet at angles of mouth; iris yellow. The younger examples have 
spines on the side of the caudal peduncle, which are obsolete in the -large ones. 
My collection contains 5 specimens (field Nos. 020, 227, 364, 636, and 684), ranging in length 
from 6 to TO inches. This species seems to be common at Honolulu.
