468 eigenmann: fish fauna of Bogota 



near Villavicencio. Tengavita is more uncertain. The fact 

 that it contains Ps. pediculatus probably places it near Susumuco 

 and Villavicencio. I have taken Marcetita of the maps to be 

 Marutiba as made out from the labels. Cameceria is a day's 

 journey north of Villavicencio. Villavicencio is given as 150 

 kilometers from Bogota or about 90 miles. Choachi is directly 

 east of Bogota at a distance of 30 kilometers or 18 miles. Ca- 

 queza is 24 miles southeast of Bogota. Fosca is south of Ca- 

 queza. The line between Choachi, Caqueza and Fosca is nearly 

 meridional. Naranjito or Naranjal, Marcetita, Perdices, etc., 

 follow each other in order on the trail from Quetame, which 

 is a few miles east of Fosca to Villavicencio. 



All of the localities are drained into the Rio Meta and through 

 it into the Orinoco. 



There are other species of Pygidium (metae, kneri), at Bar- 

 rigon, at the head of navigation on the Meta and others probably 

 occur in the localities listed. 



Of the species taken, Astrobelpus grixalvii, micrescens and 

 longifilis, Pseudancistrus daguae and Creagrutus beni also occur 

 west of the crest. 



A. grixalvii is found in streams of southern Colombia to 

 northern Peru. A. micrescens in Santander. A. longifilis 

 occurs all the way from Panama to Peru. 



Pseudancistrus daguae is abundant in the Rio Dagua on the 

 Pacific slope and Creagrutus beni is recorded in this paper from 

 Santander. 



The one species characterizing the slope is Astroblepus latidens, 

 which is known only from this slope, and everywhere on the 

 slope except at Cameceria. 



I suspect that the recorded absence of Pygidium from the 

 higher slopes of the eastern side is due to incomplete collecting.
