g. Lateral line without blue-black spot; ventrals- with outer rays scarcely filamentous, about reaching tips of 
pectorals. 
h. Tubes of pores of lateral line distinctly branched, branches usually 3 in number; body moderately slender, depth 
a little less than length of head and 3.75 to 4 in body; head 3.4. 
i. Eye large, 1.6G in snout. 
ii. Eye small, 2.GG in snout; brownish above, bright violet-red below; many blue spots above; a crescent on base of 
pectoral; caudal edged with violet and with convergent streaks of yellow poeyi 
!ih. Tubes of pores of lateral line all simple or very nearly so, not trifid; body very slender, depth much less than 
length of head, 4.5 in body; head 3.4; snout very sharp, anterior profile of head straightish and not steep; 
snout 2.8 in head; eye 2 in snout; pectoral moderate, 1.6 in head; color in spirits, pale, unmarked, except for 
small black spot behind eye. 
j. Color in life, olive-green, bluish below; back with blue spots; a yellow band on side with vague outlines; posterior 
parts paler, with rows of blue spots; head with blue bands; dorsal and anal rosy, with blue spots caudalis 
jj. Color in life, olivaceous; a broad band-like area of orange mingled with violet spots along side backward from 
head to middle of body, lower edge of this band serrate; below this a pale-violet band, darker behind; still 
lower a yellow stripe; head olivaceous, marked with blue; preorbital scarlet, with 3 violet stripes; opercles 
bright red, with 3 violet stripes, postocular black spot in the uppermost; dorsal and anal orange and yellow,

Fio. 66 .—Iridio bivittatus. 
185 . Iridio bivittatus (Bloch). Slippery Dick; Doncella. 
Head 3.2; depth 4; eye 6.3; snout 3; interorbital 4.7; preorbital 4.7; D. ix, 11; A. nr, 12; pectoral 
1.7; ventral 1.9; caudal 1.6; scales 2-28-8. Scales before dorsal reduced in size, in about 4 rows, not 
crossing median line; ventral tin with first ray moderately produced, about twice inner ray; caudal 
slightly rounded. 
Color in spirits: Grayish, a purple band from snout through eye to base of caudal, much widened 
on opercle; a fainter band, more blue, from base of pectoral to above end of anal; an oblong purple- 
black spot on upper edge of opercle, bordered behind by blue; a blue band from nape to eye; chin 
with a hi m transverse band. An example, 2.5 inches long, has longitudinal bands brown, traces of 
very faint vertical dark bars, and 2 small dark spots near base of front of soft dorsal. 
This species is gorgeous in color, but of little value as food, the flesh being dry and insipid. It is 
found throughout the West Indies, north to Pensacola and Beaufort, N. C., and south to Brazil, and is 
usually very abundant along weedy shores and reefs. Specimens, 2.5 to 5.5 inches long, obtained 
at Mayaguez, Fajardo, and Culebra; 4 from San Geronimo.
