cape jerroa; 115 : 
body is covered with short whitish hairs ; the other 
half with long black hairs, and terminated with 
a white feather tuft, an inch long. On the hind 
legs, an inch above the feet, are two long toes, 
armed with nails ; the back part of each leg is 
naked. The length of the body is eight inches and 
a half; of the tail ten. It is found fijom the 
Caspian Sea to the river Irtish ; it is of the size 
of a rat ; it is of the colour of the former, except 
that the rump, on each side, is crossed with a white 
line. 
The middle variety has its nose more lengthened, 
and its ears shorter and broader ; its tail is thicker, 
and not so elegantly tufted ; its hind legs are 
shorter ; and its coat is longer and thicker. It is 
found beyond lake Baikal, also in Barbary and 
Syria, and even as far as India. 
The pigmy differs from the greater, in wanting 
the white circle round the nose, in having a less 
tuft to the tail, and the end just tipt with white. 
It agrees entirely in form, but is far inferior in 
size to even the middle variety. It inhabits the 
same countries with the greater. 
These three agree in manners with the Egyptian 
species. Whether these ought to be reckoned 
different species instead of varieties, or whether 
they are some of them varieties of the Egyptian, 
is not yet ascertained.
