)f dorsal, 3; longest anal ray, 2; base of anal, 2; length of pectoral, 

 Li; ventral, If; upper lobe of caudal, li; deptli of caudal peduncle, 2. 

 [Dorsal, 1<>; anal, 11; ventral, S. Scales, 25. 



Front of head rounded in profile; tins all rounded; ventrals ii little 

 Rn advance of dorsal. 



Color of specimens that had been a short time in formalin: Scales 



Ion dorsal part of l)ody tinoed with yellow; 3 rows of orange yellow 



spots, one on etlch scale, extending along side of body. Pectoral fin 



Iwith a little orange coloring; ventral, anal, and caudal bright oi-ange 



fed; the color more brilliant near edges of fins. A dark lateral band 



jnding anteriorly in a dark spot just behind opercle, and posteriorly 



[n a darker more conspicuous spot at base of caudal; these markings 



lore conspicuous in the 3^oung. 



Some smaller specimens from Santa Rosa, Ecuador, differ in not 



having the small lateral spots, and in having a larger eye. 



In the plate published b\' Cuvier and Valenciennes," the dorsal is 

 truncate across the ends of the ra3\s, leaving the corners sharp. The 

 dorsal should be broadl}' rounded and without angles. The caudal 

 lobes are too sharp, and the lower jaw projects too much. 



Family CHARACINID.E. 



2o. CURIMATUS TROSCHELII (Gunther). 



A single specimen taken in the market at Guayaquil. It agrees 

 very well with Doctor Giinther's description of the type. 



21. PROCHILODUS CAUDIFASCIATUS, new species. 



Head, 2f in length to base of caudal; depth, 3i. Eye, between eye- 

 lids 7 in head; snout, 2; interorbital space, 2; third dorsal ray, li; 

 base of dorsal, 1|; length of pectoral from base of first spine, If; 

 second anal ray. If; base of anal, 2i; depth of caudal peduncle, 2^. 

 Dorsal, 12; anal, 10; ventral, 9. Scales, 47. 



Eye with thin membranous eyelids; its anterior edge at the middle 

 of the length of the head; the middle of the eye a little below the level 

 of the angle of the mouth, and vertically equidistant from tiie dorsal 

 and ventral outlines of head. Cavity beneath preorl)ital l)one, into 

 which maxillary elements retreat, fails to reach eye by a space half 

 the diameter of eye. Maxillary elements forming a thick rounded 

 projection beyond the mandible. When mouth is closed, its incision is 

 directed obliquely in a line that if continued would extend through the 

 center of eye. Teeth thin, small, and leaf like, in a single row at the 

 outer edge of a thick spongy tissue that deeply covers the bones of the 

 mouth; their edges outward toward edge of mouth. Near front of 

 mouth on each jaw a single row of similar teeth curves inward and
