Rabbit (Oryctolagus cuniculus, Linn.).

The Rabbits and the Hares being comparatively large and familiar members of our native fauna do not appear to stand in need of much space being devoted to them. Familiar as the two common species may be they require to be distinguished not only one from the other, but also from the two other and less familiar species, and in addition there may be a few facts of organisation and habit that are not well-known to all our readers. All members of the family Leporidæ, there are certain structural features in which they all agree in a general way. They belong to the section of Rodents known as Duplicidentata, because in the upper jaw there are always two pairs of incisors. All the other Rodents have only one pair, and they form the division Simplicidentata. The dentition of the Rabbits and Hares is therefore as follows: i 2/1, c 0/0, p 3/2, m 3/3 = 28.

The ears are remarkably long and out of all proportion to the size of the body when compared with other Mammals. If laid forward over the face they reach nearly to the tip of the nose. The eyes are large and prominent and placed well to the sides of the head. The hinder legs are longer than the forelegs, and so greatly developed as to be the main propelling power. Instead of pads on the soles to protect the foot and legs from the jars incidental to hard running, the Leporidæ have all the feet covered beneath with a thick coating of hair which gives a firm grip either on hard rock or slippery snow. The tail is very short and turned up. The fur is of triple formation: there is a dense, soft, woolly under-fur, through which push longer and stronger hairs and give the coat its colour, and a still longer but much less numerous set, scattered among the others. The two longer sorts of hair are more or less ringed. The coat becomes thicker in winter.

They are sexually mature at a very early age, and often begin to breed before they have attained to full size. The females are distinguished by the form of the head, which is longer and more delicately modelled than that of the male. The males (bucks), too, are restless and quarrelsome. They are promiscuous breeders, and the entire care of the family falls upon the mother (doe).
