The classic work by C. T. Regan on the freshwater fishes of Central America is available electronically at: http://web4.si.edu/sil/bca/explore.cfm (click on Pisces and navigate from there).

A pdf (printable) version is planned but unfortunately, is not ready currently.

There are 305 images(jpg)! Which are about catfishes?

The catfishes run from pages 110-141, and from plates 15-23.
