about one scale in width, beginuing at posterior margin of operele and 

 extending backward in a direct line, meeting the lateral line under pos- 

 terior fourth of soft dorsal, thence continuing to base of caudal chiefly 

 below lateral line; ceuter of each scale in the band with a faint dark 

 1)lotch, these forming a rather distinct darker line through the mid- 

 dle of the light one; 3 other faint dark bands along side, 1 above and 2 

 below the light band; operele with a yellowish tinge, a dark spot at 

 angle; fins all light yellowish, soft dorsal mottled with blackish; a 

 faint blotch on axil of pectoral. Pacific coast of tropical America; very 

 common at Mazatlan and Panama, south to northern Peru; quite variable 

 in depth of body, width of preorbital, and length of spines. Here described 

 from a specimen 9 inches in length, from Eio Mulege, Lower California.

1698. BRAiHTDEUTEBUS AXILLARIS (Steindachner). 



(Burro Blanco.) 



HeadSf; depth 31; D. XII, 16; A. Ill, 9; scales 6-50-10. Body rather 

 robust, compressed, the back moderately arched ; dorsal fin deeply notched ; 

 preoijcrcle with small serrje ; suprascapula finely serrate ; preorbital broad, 

 about as wide as eye; anal spines small or moderate, the second little, if 

 any, longer or stronger than third, 3i to 4 in head ; anal lower than the soft 

 dorsal; soft dorsal and anal largely covered with small scales; pectoral 

 fin long, nearly equal to head. Color grayish-silvery, with light and dark 

 stripes aloug rows of scales, these sometimes obscure; fins unspotted; 

 body with faint dark crossbauds; back and sides with dark stripes 

 formed by dark spots along the rows of scales ; a large inky-black axillary 

 blotch, encroaching on the rays of the pectoral fin, a color mark by which 

 the species may be known at once. Length nearly a foot. Pacific coast 

 of Mexico; not rare, but known only from about Mazatlan and Guaymas. 

 {axillaris, from the black axillary spot.)

* The specimens called elongatus by Jordan & Gilbert diifer somewhat from the elongatus 

 of Steindachner. Kenewed comparison of many examples leads us to the conclusion that 

 the specimens named leuciicus and elongatus are simply rather extreme forms of one 

 species.
