F. Major, P. Zool. Soc. London, 1897, p. 695, discusses the affinities of 
Brachyuromys , and enters into the question of the mutual relation 
of some of the groups of the Mundce ( Hesperomyince , Microtince , 
Murince) and Spalacidce with each other and with the Nesomyince of 
Madagascar. The Nesomyince are the lowest of the Muridoe, being 
forerunners of the American Hesperomyince , the Old-World Murince , 
and the Microtince. Brachyuromys bears close affinities to the 
Spalacidce , which are regarded as lowly-organized Muridce.
