THE LIFE OF MAMMALS 
variegated. The crab-eating fox dog is common throughout 
the forested parts of the whole Amazon basin, and gets its 
name from its fondness for crayfish; it often collects in packs 
and runs down deer. Azara’s dog, or the colpeo, is known 
throughout the whole continent east of the Andes, and has been 
well described by Azara,'! Hudson,® and others. It has much 
the habits of coyotes, but takes more rapidly to life in forests. 
Everywhere it is foxlike in its fondness for poultry, and in 
Paraguay destroys a great amount of sugar cane, while eating 
but a little. 
In the small reddish variety of wolf native to India ** we have 
a form which seems to bridge the narrow gap between wolves 
and jackals,—the latter, small, active, noisy, wolf- 
like animals inhabiting Africa and southern Asia. 
Many kinds of jackals are known — none better than those of 
Egypt and Syria, especially Canis lupaster, upon which Ander- 
son furnishes the following notes: — 
Jackals. 
“They live in the desert surrounding cultivated land, and descend from 
the gullies and hills at sunset, making their way into the palm-groves and 
gardens, where they often make night hideous with their howls. At 
Dakhel they appear to live chiefly on fruit, which is plentiful, and consists 
of dates, mulberries, apricots, etc., at different seasons. In the north of 
the Fayum the jackals .. . live entirely on fish.... Unlike the hyena, they 
often congregate together at night near one’s tent, and keep up an infernal 
din for hours; their cry is usually a Jong howl broken into a number of 
yelping notes at the end. Like hyenas, the jackals do not penetrate any 
distance into the desert.” 
In South Africa the red jackal and the side-striped jackal 
are prevalent, and do much damage to sheep, poultry, etc., 
and like our coyote are successfully kept out by wire fences, 
which they will not jump. The well-known Abyssinian black- 
backed species * has similar traits; and that country has also 
a rarer and very interesting wolflike jackal called the kaberu. 
The most familiar of the Asiatic jackals is the common pale
