froui the pectoral fin to the uiiddle of caiidal peduncle; belly with many 

 similar sj.ots smaller in size and somewhat sharper in outline; a row of 

 conspicuous black spots, irregular in size, shape, and position, along 

 back at the base of dorsal spines; a black line as wide as pupil from 

 nape to eye, a similar line from eye to posterior end of maxillary ; a faint 

 li"-ht streak across cheek posteriorly; cheek and base of pectoral dusted 

 with fine dark points. The small oue is bright green without distinct 

 markings on body; a silvery bar, running posteriorly from tip of snout 

 through eye, across cheek, to the middle of operclc; no bar downward 

 from eye to maxillary, or from eye to nape as in the large oue. {fiavidus,

2767. APODICHTHYS UNIVITTATUS, Lockington. 



D. about XCV; A. about I, 40. Body elongate, much compressed, band- 

 like, preserving almost same depth to about posterior fifth of body, thence 

 tapering more rapidly to caudal fin. Head 7; depth nearly 10 times in 

 total length; depth of caudal jied uncle about i of that of body; snout 

 obtuse, about f as long as diameter of eye, upper profile of head a con- 

 tinuous curve from snout to occiput. Interorbital area highly couA^ex 

 transversely, about equal in width to i diameter of eye. Eye entirely 

 lateral, round, contained entirely in anterior half of head; iris golden. 

 Mouth small, posterior extremity of the maxillary reaching to anterior 

 margin of eye. Teeth small. BranchiostegalsS. Dorsal continuous with, 

 but distinct from, anal, arising vertically from tip of operculum, and com- 

 posed of spines only. Anal preceded by a long, sharp, slender spine of 

 V-shaped transverse section, hollow side anterior, length of spine equal 

 to about 4 depth of fish. Distance from anal spine to tip of operculum a 

 little more than to tip of caudal. Caudal with numerous accessory rays, 

 so that its sides are almost straight, posterior margin broken in the tyj)e, 

 all rays simple. General color in spirits, light reildish, vertical fins 

 rather bright, and top of head reddish brown; tip of snout brown; a 

 silvery band (i)ossibly bluish in life) from tip of snout, across lower part 

 of eye, cheek, and opercles, terminating at about middle of length of 

 operculum, this baud bordered above by a narrower brown band. 

 Lower California, probablj^ from the gulf, A single specimen. Length 

 1.88 inches. The peculiar vitta upon each side of the head at once dis- 

 tinguishes this species from the other described forms. (Lockington.) 

 Not seen by us. {uni-vittatua, having one band.)
