anterior soft dorsal is a large ocellus, aud behind the lin is a smaller one. 

 The head ahove has 2 very distinct blue lines continued from the snout 

 over each eye, where they are most distant, and again approximating and 

 continued, 1 on each side of the base of the dorsal fin, but under the 

 tin rather broken into a linear row of spots ; another line crosses the eye- 

 ball above, aud behind the upper angle of the orbit is a line which is 

 continued to the row of scales above the lateral line; a bar crosses tlie 

 preorbital; a line runs along the suborbital chain; another line extends 

 backward from the corner of the mouth, and under the suborbital one, 

 and a blue line colors the upper lip. On each of the opercular scales is a 

 bluish blotch. The dorsal and anal fins are spotted with blue, a spot 

 existing on each scah^, and a blue bar crosses the base of the last anal 

 rays. The caudal is brownish, as are also the pectorals. The ventrals 

 dark, and the spine outside bluish, like the front of the aual. 



''These colors are retained until the fish has attained a length of more 

 than 2 inches, the chief change being efi'ected by the slightly greater isola- 

 tion of the spots on the rows above'the lateral line, so as to break their 

 continuity as lines; and especially in the fading away of the blue ring 

 and ocellus of the dorsal, which has then become very faint and is the 

 first to disappear. Finally, in the very aged individuals, more than 3 inches 

 long, the color of the body and scaly portion of the fins has become almost 

 a uniform brownish chestnut, and very indistinct traces of the lines on the 

 upper surface and sides of the head are perceptibh-. The naked portions 

 of the dorsal and anal, as well as the ventral fins, are very dark, and the 

 pectorals yellowish. The profile is also apparently steeper and more 

 convex, and the l)ody more obese. 



" This species undergoes great change with age, and on two suites of 

 specimens two nominal species were formerly based, the author having 

 been deceived by the comparatively long retention of the colors of the 

 young in several individuals, and the early assumption of the adult state 

 by others. 



" In studying the development of this species, I have had before me not 

 less than 32 individuals, exhibiting every gradation from the specimen 8 

 lines long to 1 nearly 3^ inches long." (Gill.) 



Our specimens confirm this excellent account. On comijarison of this 

 species with E.fmciis, the only constant difference we note is that of the 

 increased number of small accessory scales about the head, aud the some- 

 what broader preorbital of Eupomacenirus recfifrwnnm. Length 6 inches. 

 Cape San Lucas to Panama; abundant in rock pools; a beautiful little 

 fish, {rectus, straight; fnmium, bridle^
