praeorbital |—| the diameter of eye. Anterior teeth forming 4 or 5 

 series in the upper jaw, 3 or 4 in the lower. 10 or 11 gill-rakers 

 on the lower part of anterior arch. Scales denticvilated except on 

 the head, the lower parts of thorax and abdomen, and anteriorly 



9—11 • 



above the lateral line, 75-80 goiil^ 65-70 in a longitudinal series 



below the lateral line, 4|-6 between last dorsal spine and lateral 



line, 3 between upper and lower lateral lines. Lateral line 



23-24+12-1 3. Dorsal XIX-XXI 1 3-14, the spines only slightly 



increasing after the fifth or sixth, the last -^ the length of head. 



Anal III 10. Pectoral f-f, ventral |-| the length of head. 



Caudal peduncle li-lf as long as deep. Olivaaeous, sometimes 



with white spots on the body ; a dark stripe from snout through 



eye to extremity of operculum ; a dark ocellus on the lateral line 



above the pectoral, another on the upper part of the base of caudal ; 



soft dorsal and caudal greyish, with light spots.

Crenicichla geayi Pellegr. Bull. Mus. Paris, 1903, p. 123, and 

 Mem. Soc. Zool. France, xvi. 1903, p. 375, pi. vi. fig. 4 (1904). 



Depth of body 5-5| in the length, length of head 3^. Diameter 

 of eye 5 in the length of head, length of snout 3^, interorbital 

 width 4. Nostril nearer to eye than to tip of snout. Maxillary 

 extending to below middle of eye ; depth of praeorbital f the 

 diameter of eye. Anterior teeth forming 4 series in the upper 

 jaw, 3 in the lower. 9 or 10 gill-rakers on the lower part of 

 anterior arch. Scales denticulated, except on the head, the lower 

 parts of thorax and abdomen and anteriorly above the lateral line, 

 65j| (^), 54 (57) in a longitudinal series below the lateral line, 4 

 between last dorsal spine and lateral line, 2 between upper and 

 lower lateral lines. Lateral line 24-25+10-11. Dorsal XX 12 

 (XXII 11), the spines only slightly increasing from the tenth, the 

 last 5 the length of head. Anal III (8) 9. Pectoral |-|, ventral 

 4 the length of head. Caudal peduncle longer than deep. 

 Brownish ; a dark stripe from eye to extremity of operculum ; 

 sometimes a series of blotches along the middle of the side ; a 

 dark spot or ocellus on the upper part of the base of caudal. 



R. Orinoco. 



1. (159 mm.) Near Bogota. Mr. Cutter. 



This specimen agrees so well with the figure of the typical 

 example of C. geayi given by Pellegrin that I have no hesitation 

 in referring it to that species. The number of fin-rays (D. XX 12 

 instead of XXII 11, A. Ill 9 instead of III 8) and of scales in a 

 transverse series (fg instead of 25), although difierent, fall within 

 the limits of individual variation, whilst the presence or absence 

 of a series of blotches on the side is of very slight importance
