EiGENMANN AND Henn: Three New Species OF Characid Fishes. 89 



the case in L.friderici. Pectorals reaching nearly three-fourths of the 

 distance to the ventrals, the latter more than half way to the anus. 



Each scale of the sides and back has a dark area at the base. Dorsal 

 area steel-blue or bluish-green, ventral region and belly yellowish. 

 Young specimens have alternating bluish blotches and transverse 

 pinkish bars on the back. Sides with a series of three heavy black 

 spots or blotches, the first below the dorsal, or midway in the length 

 without caudal, the third at the end of the caudal peduncle, and the 

 center one ending before the vertical from the adipose. These are 

 present in all specimens, and occupy each about four scales in the lateral 

 line and the series beneath it. Dorsal, pectorals, and caudal dusky, 

 without definite bands of color ; ventrals and anal blackish, with a broad, 

 white, outer margin. 



3. Astyanax magdalenae sp. nov. 



5822 a, C. M., type, 53 mm. Girardot. Eigenmann. 

 13611, I. U. M., paratype, 61 mm. Apulo. Gonzales. 



Closely related to A. stilhe (Cope) differing in the greater depth, 

 the shorter anal, and the lack of a median series of preventral scales. 



Head 3.5-3-8; depth 2.33; D. 11 ; A. 33-34; scales 8-36 or 37-7 (to 

 ventrals), snout 1.3 in eye, 4-4.5 in head; eye 3-3.3 in head and equal 

 to interorbital. 



Dorsal and ventral profiles equally and strongly arched; predorsal 

 area without a median series of scales, those of the two sides over- 

 lapping, an occasional median scale near the origin of the dorsal; 

 preventral area keeled, scales of the two sides apposed in the mid-line. 



Interorbital convex, smooth; occipital process elongate, sharp, 

 about one-fourth of the distance from its base to the dorsal, bordered 

 by three large scales. Frontal fontanel bluntly triangular, as wide as 

 the parietal and about two-thirds as long as the parietal without the 

 occipital groove. Second and third suborbitals leaving a narrow naked 

 margin behind and below. Maxillary as long as the eye, shorter than 

 the mandible, which is equal to the snout and half the length of the 

 eye. 



Premaxillary with four broadly tricuspid teeth in the outer row and 

 five brown-tipped four- to five-pointed teeth in the inner row. Maxil- 

 lary with a single minute tooth in the upper angle. Mandible with 

 five sharp three- to four-pointed teeth.
