MAMMALIA. 
The SoKiNAH {EcMnopSy Martin) — 
Is a Madagascar animal, which differs chiefly from the Urchins in its dentition, having but four upper 
incisors, of which the medial are large, and placed before the others ; the superior canines (or what 
may be designated as such) are tuberculated behind ; there are five molars in all to each side of the 
upper jaw, longitudinally very short, but broad, a groove passing continuously along their crowns ; two 
small lower canines, three inferior false molars inclining forward, and four true molars obtusely 
tuberculated. 
E. Telfairi, Mart., is the only ascertained species ; and the form may be regarded as subordinate to Erinaceus.'] 
The Tenkecs {Centenes, Illiger) — 
Have the body covered with spines, like the Urehins [but more slender and bristle-like] ; they do not, 
however, possess the faculty of rolling themselves so completely into a ball : they have no tail ; their 
muzzle is very pointed, and their teeth are very different. On each jaw are from four to six incisors, 
and two large canines : next follow one or two small teeth, and four triangular molars with sharply 
tuberculated crowns. They are natives of Madagascar, one speeies having been naturalized in the 
Mauritius : are also nocturnal animals, which pass three months of the year in a state of lethargy, 
although inhabiting the torrid zone. Brugiere even asserts that it is during the greatest heats that 
they become torpid. 
[Three if not four species have been ascertained ; one of which, the Tendrac of Biiffon {Erinaceus setosus, Lin.), 
with six incisors to each jaw, composes the Ericuhcs of Is. Geoffroy. 
The foregoing genera have little or no tail, whereas the following have very long tails.] 
The Gymnures {Gymnura, Vig. and Horsf. \EcMnosorex, Blain.] ) — 
“ Appear to approach the Banxring in dentition, and the Shrews by the pointed muzzle and scaly tail. 
There are five unguiculated toes to each foot, and tolerably stiff [almost spinous] bristles growing 
among woolly hair, [resembling the close fur of the Shrews.] It can only he properly classed when its 
anatomy is known.”* [The general aspeet is that of a Tenrec, with a long, naked, and scaly tail. There 
are six incisors to each jaw, the medial above widely separated, large, and resembling canines ; the 
others lateral, and successively smaller : those below are separated into two pairs, the middle ones 
being somewhat apart, and one smaller on each side. The canines are moderately large, and somewhat 
curved, those of the upper jaw having two fangs : next follow, on each jaw, two pairs of smaU false 
molars, succeeded by one larger above, and two below ; and the tme molars are four in number above 
and three below, square, and tuberculated as in the Urchin. 
The only known species (G. Rafflesii) inhabits Sumatra, and is larger than the Urchin of Europe. 
The various preceding genera have small but not minute eyes. 
The Macroscelles {Macroscelides , Smith ; Erinomys, Blain. ; Rhynomys, Lichst.) — 
Compose a well-marked genus, somewhat resembling the Shrews, but with large eyes and more elong- 
ated hind-feet : their fur is long and soft, and of very fine texture. They have six (lateral) incisors to 
each jaw, minute canines, and on either side five sharply tuberculated molars. Their habits are 
diurnal, and they retreat into burrows or beneath stones on apprehension of danger. 
Eight species are known, all from South Africa except one, which inhabits Algiers. They are called Elephant 
Mice in the Cape Colony.] 
The Banxrings {Tupaia, Kaff. ; Cladohates., Fr. Cuv. \_Glisorex, Diard. ; Hylogale, Tern.] ), — 
A genus lately characterized, from the Indian Archipelago, the teeth of which bear some resemblance 
to those of the Urchins, only that their middle superior incisors are proportionally shorter, and there 
are four to the lower jaw, more elongated, [and projecting forwards as in the Lemurs] ; they also [do 
not] w'ant the tuberculous tooth behind. These animals are covered with hair [soft and glistening, but 
not fine in texture], and have a long bushy tail ; and, contrary to the habits of other Insectivora, 
they ascend trees with the agility of a Squirrel, but their pointed muzzle renders them easily distin-
