pies examined as to this point, the gill rakers are as follows: 20 + 25, 

 23 + 24, 21 -f 23, 19 -f- 30, the longest contained H to If in eye. Scales large, 

 thin, and deciduous, a few only remaining on the specimens at hand. 

 Origin of the dorsal fin equally distant from the base of the caudal fin 

 and tip of snout or front of eye. Anal inserted under beginning of poste- 

 rior third of base of dorsal ; pectorals not reaching ventrals, the latter f 

 distance to front of anal. Color light olive, with broad, well-defined lat- 

 eral silvery streak of nearly uniform width, usually narrowing anteriorly 

 and 011 middle of caudal peduncle, its width in our largest specimen 

 diameter of eye ; the silvery streak has a slight golden tinge; a narrow 

 dark vertebral line, which widens on the nape ; occiput blackish. Ver- 

 tebrae 40, counted in 1 example only. This species differs from Stoleph- 

 orus cultratus in its slenderer body, shorter snout, wider opercle and 

 smaller teeth ; the belly is also not sharply carinate, the dorsal is more 

 anteriorly placed, the ventrals are farther back, and the silvery streak is 

 wider anteriorly. It differs from S. dclicatissinms in its longer, slenderer 

 head and body, smaller eye, longer, sharper snout, and much wider, bet- 

 ter-defined silvery streak. Length 1 to 2 inches. Panama ; common.

Head 3| to 3 r in length to base of caudal; depth 4 to 5; eye 3| to 4 in 

 head. D. 12; A. 25 or 26; scales 41 or 42. Body somewhat compressed and 

 elevated, the belly not carinated nor serrated. Teeth in both jaws, and 

 on palatines, a few on vomer; maxillary covered with teeth its entire 

 length and reaching beyond base of mandible, but not to opercular mar- 

 gin. Gill rakers 10 -\- 12, the longest a little more than ^ the eye. Origin 

 of dorsal midway between base of median caudal rays and center of eye ; 

 anal not quite as long as head, its origin below the middle of dorsal; 

 lower caudal lobe longer than upper; longest ray equaling length of the 

 head; shortest caudal ray 2 in longest. Pectorals not reaching ventrals, 

 If in head. Both anal and dorsal fins preceded by a rudimentary spine, not 

 | length of first true ray. Color translucent, with a distinct broad silvery 

 stripe as wide as the eye, growing more diffuse at lower anterior edge, 

 narrowing on caudal peduncle, and becoming fan-shaped on the base 

 of caudal ; tip of snout black ; a distinct median band of black specks 

 extending from tip of snout to base of caudal; 110 distinct black mark- 

 ings on fins. Close to Siolephorus deUcatissimus, but with larger head, 

 wider lateral baud, and greater number of dorsal and anal rays. Length 

 3 inches. Found in the Astillero at Mazatlan ; not very abundant. (Named 

 for Mr. Norman Bishop Scofield, a member of the Hopkins expedition to 

 Sinaloa.)
