23. On New Species of Fishes from the Rio 

 Meta Basin of Eastern Colombia and 

 on Albino or Blind Fishes 

 from near Bogota 



By Carl H. Eigenmann 



Copeina metae Eigenmann, sp. nov. 



Copeina eigenmanni Regan, in part. Ann. Mag. Nat. Hist., (8), x, 393 



(Bogota). 



13251a I. U. M. type, 35 mm.; 13251 I. U. M. paratypes, 34, largest 43 mm. 



Barrigona, Rio Meta, Colombia. Coll. and Manuel Gonzales, 1914. 

 Head 4; depth 5; D. 10; A. 10, rarely 11; lat. 1. 22-24; eye about equal to 

 interorbital, little greater than snout, a little less than 3 in the head; length 

 of caudal peduncle equal to head from snout to upper angle of gill-opening; 

 origin of dorsal nearer base of middle caudal rays than to head; a black spot 

 on middle of anterior dorsal rays, sometimes extending to the tip of the rays; 

 anal faintly margined with dark; a broad dark band from chin to caudal, 

 faintly to the end of the middle caudal rays, most conspicuous and nearly as 

 wide as the eye along the entire body, most intense just behind the head; a 

 narrow light band above the dark band from the angle of the mouth to the 

 base of the upper caudal lobe; back dusky. Markings of the sides in one 

 specimen obscure. 



Regan records presumably this species from Bogota. His specimens 

 were probably collected in the Meta, and some at least of those reported from 

 Bogota represent the present species. 



Regan says of them: "In the smaller examples there is sometimes an 

 indistinct dusky band on the anterior part of the body and an indication of 

 a pale stripe above the^ark one on the head. In the larger ones, from Bogota , 

 a silvery stripe from eye to caudal fin separates a broad dark band below from 

 the dark colour of the back." 



Otocinclus spectabilis Eigenmann, sp. nov. 



13253a. I. U. M. type, 38 mm.; 13253 I. U. M. parat^i^es, 9, 29-38 mm. 

 Quebrada Cramalote, Villavicencio. Coll. Manuel Gonzales, 1914. 

 Head to end of occipital about 2.5 in the length; depth 5.5; D. I, 7; A. I, 

 5.1; eye 3.5 in snout, 7 in head, 3 in interorbital; plates 22; ventral surface 

 with a large anal plate, a wider, shorter, variously shaped plate in front of 

 the anal plate, plates in front of this plate variable, sometimes a series of 

 three plates extending entirely across the belly, sometimes two series, some- 

 times a series of three with an extra middle plate; a broad coracoid plate in
