Overview

Excerpt from A Monograph of the Fishes of the Family Loricariidae In the present paper 189 species are recognised as valid, 34 of which are described as new to science. Our knowledge of the geographical distribution of these Species is so very incomplete that generalisations are of little value. Most of the genera seem to be represented in the principal river-systems of South America, the rivers south of the La Plata system excepted, and the species seem in many cases also to have a very wide distribution, as might be expected when it is considered that the Amazon system actually communicates with that of the Orinoco on the north, whilst the head-waters of the southern tributaries of the Amazon are in many cases only separated by a few miles from those of the rivers of the La Plata system. Whilst it is clear that the Magdalena, Orinoco, Amazon, and La Plata systems, and also the coast-rivers of Eastern Brazil, have each several characteristic species which do not extend into other river-systems, still in the present state of our knowledge it is difficult to say which are the species with their distribution thus restricted.
