Afrlcin Freshwater Fishes. 



With the completion of vol. iv. of the ' Catalogue of Freshwater 

 Fishes of Afriea ' (London, the Trustees of the British Museum, 

 1916) Mr. G. A. lioidenger has earned the gratitude, not merely of 

 students of African fishes or of ichthyologists in general, but of all 

 who are concerned with tlie problems of geographical distribution, 



h\ these four volumes Mr. lioulenger has described the largest 

 collection of freshwater tishcs ever brought together from one area 

 in any part of the world, cj^mprising as it does over 15,000 specimens 

 now in tlie liritish Museum and an almost equal number in the 

 museums of the Nile Survey, the Congo (Tervueren), S. Africa, 

 Paris, and Luxemburg. 



How immensely our knowledge of the freshwater fishes of Africa 

 has grown during the last thirty years or so may be gathered from 

 the fact that in 18S0 only 255 species were known. Ten years 

 ago this number had increased to 974. In the present catalogue 

 no le-is than 1425 species are described, and this increase is largely 

 due to the zeal and enthusiasm of the author of this catalogue, of 

 wiiieh he may well be proud. 



Though it would materially have increa«'ed the bulk of these 

 volumes, we venture to think that their value would have been 

 immensely increased by the addition of internal anatomical 

 characters — or, at any rate, of skeletal characters — and field-notes 

 contributed by the collectors. But there were probably good 

 reasons for reducing the work to the smallest possible dimensions. 

 Happily it is well illustrated and has a good index.
