The genus Gepliyrocharax has hitherto been known from five species, 

 G. melanocheir from the Magdalena between Honda and the coast, G. 

 caucamis, in the Cauca basin between Cartago and Cali, G. chocoensis 

 from the San Juan and the Atrato basins, G. atricaudata from the Pan- 

 ama Canal Zone, and G. intermedins from Panama. The present species 

 reaches a length of about 45 mm. 



Head 4.33; depth 3.33 to 3.66; D. 9; A. 30 to 32. Scales 5 to 6.5-40 

 to 42-5; eye longer than snout, 3 in the head, slightly less than inter- 

 orbital. 



Very similar to (7. chocoensis and G. melanocheir, the pectoral in the 

 male not black tipped, the shoulder without a vertical bar; the frontal 

 fontanel extending to the ethmoid.

15133 and 15134 are small specimens, mostly between 30 and 40 mm. 

 These have a dark wedge entering the middle of the dorsal from in front. 

 This spot is much less conspicuous and may be absent in the adult. Some 

 of the smaller have a conspicuous humeral spot and a small caudal spot.

15132, I. El Concejo, Rio Tiquirito, August 1, 1918. 



D. 49; scales 61 and 62. Shoulder spot small and inconspicuous. 



It is possible that this will form another of the "statistical" species 

 of the genus Roeboides. There are several such west of the Eastern 

 Andes of Colombia. There being but one specimen available for exam- 

 ination, the determination of its closer affinities may be left in abeyance.

 bital 4; snout freely protractile.
