The Chrysochloridæ include only the five species of the typical 
genus, and are limited to Africa south of the Equator. Although 
formed for digging, the modifications of the body and limbs for 
this purpose are quite different from those of the Talpidæ, since 
the former have long clavicles and a hollowed-out thorax instead 
of short clavicles and a lengthened manubrium. 
The family Talpidæ includes twelve genera and eighteen spe- 
cies and has a wide distribution in the Palæarctic, Nearctic and 
northern part of the Oriental regions. Though most are fossorial, 
some (Myogale) are natatorial, or (Uropsilus) cursorial, but all 
agree in the remarkable peculiarity of a double articulation of 
the humerus with the scapula and clavicle. The incisors, canines 
and premolars vary extremely in form, but the molars are uniform 
in number (33), and nearly so in shape. The fossorial habits of 
the Talpidæ are correlated, in the fore-limbs, with an elongated 
manubrium and small quadrate clavicles, and, in the hinder, by 
an inward curvature of the os innominata, This is carried to 
such an extent in some species (Mogera wogura, e. g.) that the 
bones meet between the acetabula. The genera are distinguished 
principally by the teeth.
