86 MAMMALIA. 
longest, and on each side three false molars, three bristled with 
points, and a small one studded with tubercles.(1) 
E. europxus, L.; Buff. VII, vi. (The Common Hedgehog. ) 
Ears short; common in the woods and hedges ; passes the win- 
ter in its burrow, whence it issues in the spring with an ampli- 
tude and complication of the vesicule seminales that is almost 
incredible. To insects, which constitute its ordinary diet, it 
adds fruit, by which at a certain age its teeth become worn. 
The skin was formerly used to dress hemp. 
E. auritus, Pall.; Schreb. CLXIII. (The Long-eared Hedge- 
hog.) Smaller than the preceding; ears as large as the two- 
thirds of the head, otherwise similar to the europeus in form 
and habits. It is found from the north of the Caspian sea, as 
far as Egypt inclusively. 
CenTENES, Illig. 
The body of the Tenrec is covered with spines like the Hedge- 
hog. It does not however possess the faculty of rolling itself so 
completely into a ball: there is no tail; the muzzle is very pointed, 
and the teeth are very different. There are four or six incisors, and 
two great canini in each jaw. Behind the canini are one or two 
small teeth, and four triangular and bristled molars. Three species 
are found in Madagascar, the first of which has been naturalized in 
the Isle of France. It is a nocturnal animal, which passes three 
months of the year ina state of lethargy, although inhabiting the 
torrid zone. Brugicre even assures us that it is during the greatest 
heats that they grow torpid. 
Erinaceus ecaudatus, L.; Buff. XII, lvi. (The Tenrec.) Co- 
vered with stiff spines ; only four notched incisors below. Itis 
the largest of the three, and exceeds the hedgehog in size. 
Erinaceus setosus, L.; Buff. XII, lvii. The spines more. 
flexible and setaceous ; six notched incisors in each jaw. 
Erinaceus semi-spinosus. Covered indiscriminately with 
spines and setz; striped with yellow and black; its six incisors 
and canini are all slender and hooked ; size hardly that of a 
Mole.(2) 
(1) Pallas has noted as an interesting fact, that the Hedgehog eats hundreds: of 
Cantharides without inconvenience, while a single one produces the most horrible 
agony in the Dog and the Cat. 
(2) Buff., Suppl. Il, pl. 37, has mistaken it for a young Tenrec. Voy. a la 
Chine, I, p. 140, gives a wrong description of the teeth.
