of this species are sometimes much longer than such as are usually met 

 with, and he suspects that R. Crossii, Gray, is this species. 



Africa possesses four or five species of rhinoceros, all of them double- 

 horned, and without incisors. 



The curious genus HYRAX is usually placed near the Rhinoceros family. 

 It forms the family Hyracidce, and the tribe Lamnunguia, Wagner. They 

 are animals of small size, about that of a rabbit, and have quite similar 

 molars to the Rhinoceroses ; the upper jaw has two stout incisors curved 

 downwards, and during youth two very small canines ; the lower jaw has 

 four incisors and no canines. The fore-feet have 4 toes ; the hind-feet 3, 

 all furnished with flat hoof-like nails j they have no tail, have a short 

 muzzle, and they are covered by hair. Several species are known from 

 Africa, and one from Arabia and Palestine, supposed to be the coney of 

 our version of the Scriptures, Hyrax syriacus. It was considered by 

 the Jews one of the animals that chew the end. 



The Tapirs, TAPIRID^E, have six incisors and two canines in each jaw, 

 separated from the molars by a wide interval. The fore-feet have 4 toes, 

 and the hind-feet 3. The snout is prolonged into a short fleshy trunk, 

 and the skin is covered with short close hair. The tail is very short, 

 and the ears are small and upright. They are animals not unlike pigs in 

 their general form ; frequent damp forests, and are fond of the water. 



One species is found in the Malayan peninsula and islands, Tapirus 

 malayanusy and it has been killed in Southern Tenasserim. The only 

 other two species are inhabitants' of South America, Tapirus americanus 

 and T. villosus, of the Andes. 



The remarkable fossil genus Dinotherium was at first described as a 

 tapir. It is now considered to have been an aquatic animal, like the 

 dugongs ; and this would perhaps be the best place to intercalate the 

 family of Sirenia, or herbivorous Cetacea, but I will describe them at the 

 end of the next tribe.
