Myology, especially Myomorpha ; Parsons, P. Zool. Soc. London, 1896, 
p. i 51 . Classification ; Thomas, t. c. p. 1012. Taking as a basis 
Alston’s scheme of 1876, the chief object of this paper is to place in 
their proper positions the genera subsequently described. In regard 
to the larger groups, Alston’s arrangement is followed so far as pos- 
sible, but it has been thought better to elevate the subfamily Buthy- 
crgincc into a family, to make two families of the Ilystriculcc, one for 
the Old-World, and one (Erithizontidce) for the New-World Porcu- 
pines, and to giVe to the subfamilies Geomyinoi and Heteromyince,Bathy- 
erginon and Pedetinca family rank, the latter group being transferred 
to the HystricomorpTia. For African forms, see De Winton (71).
