Of the lower animals, mice, rats, guinea-pigs, rabbits, squirrels and monkeys are susceptible to the bacillus; horses, cattle, sheep, goats, pigs, dogs and cats are more or less resistant, but cats and dogs have been known to die of plague (Oporto, Daman, Cutch and Poona).
Baboons (Cynocephalus porcarius) and monkeys of different kinds frequent the mountains and rocky kloofs and bush and timber lands.
Among these are two monkeys of the genera Macacus and Cercopithecus, a stag (Cervus hippelaphus), a small hare, a shrewmouse, and the ubiquitous rat.
A series of the apes, arranged from lower to higher orders, shows gradations from a brain little higher that that of a rat, to a brain like a small and imperfect imitation of a man's; and the greatest structural break in the series lies not between man and the manlike apes, but between the apes and monkeys on one side, and the lemurs on the other.
UAKARI (Ouakari), the native name of certain tropical American monkeys, distinguished from all other New World monkeys by their short tails.
The Formosan fauna has been but partially ascertained; but at least three kinds of deer, wild boars, bears, goats, monkeys (probably Macacus speciosus), squirrels, and flying squirrels are fairly common, and panthers and wild cats are not unfrequent.
These monkeys are the African representatives of the Indo-Malay langurs (Semnopithecus), with which they agree in their slender build, long limbs and tail, and complex stomachs, although differing by the rudimentary thumb.
In a zoological sense the term is extended to embrace all the monkeys of the Asiatic genus Semnopithecus, which includes a large number of species, ranging from Ceylon, India and Kashmir to southern China and the Malay countries as far east as Borneo and Sumatra.
Fort de la Moune (so called from the monkeys said to have haunted the neighbourhood) is at the western end of the harbour, and commands the road from Oran to Mers-elKebir (see below).
These monkeys are characterized by their lank bodies, long slender limbs and tail, welldeveloped thumbs, absence of cheek-pouches, and complex stomachs.
