NATURAL HISTORY. [UPPER FLOOR. 
Giraffe, or Camelopard, brought from Africa by the late 
Lieut.-Col. Denham; several species of Antelope, the 
Small, and the Common Musk, and the Bouquetin des 
Alpes, or Ibex. Over these Cases are the Ursine Seal 
(Phoca ursina , Linn.), an adult specimen of Weddell’s 
Sea-Leopard, and the Long-bodied Seal of Parsons 
[Halichcerus gryphus, Gray). 
Case 21 contains several of the Weasel tribe, as the 
Polecat, Martin, Common Weasel, and Stoat (Mustela pu- 
torius ? martes , vulgaris , and erminea , Linn.) The latter 
animal is of a pale chestnut-brown colour in summer, but 
becomes white in winter, and in that dress forms an import¬ 
ant article of the fur trade, under the well known name of 
Ermine; the tip of the tail is black at all seasons of the 
year. These animals inhabit the northern parts both of 
Europe and Asia, and are very abundant in Norway and 
Siberia. In the upper part of this Case are some large 
Bats ( Pteropi ), from India and New Holland. 
Case 22 contains the small digitigrade carnivorous 
animals, as the Paradoxuri, from India; also some of the 
lesser marsupial animals, as the Opossum, ( Didelphis 
virginiana , Linn.) from Brazil, the Spotted Weasel 
( Dasyurus macrourus ), a young specimen of the Wombat, 
(Phascolomysjusca, Desm.), the Pigmy Opossum ( Didel - 
phis pygmaea , Shaw), and the Flying Opossum ( Didelphis 
petaurus, Shaw), all from New Holland. 
Case 23 contains the minor animals belonging to the 
order Glires, as the Water Rat, ( Mus amphibius , Linn.), 
Dormice, (M. glis, Linn.), Pouched Rat, (M. bursarius , 
Shaw), Chinchilla, ( Chinchilla Laniger , Gray), valuable 
for its peculiarly soft fur; and a series of Squirrels from 
various parts of the world. 
Case 24 contains other Glires, as the Flying Squirrel, 
(Scuirus volans, Linn.), Hare, Rabbit, (Lepus timidus, and 
L. cunicidusy Linn.), and the prehensile-tailed Porcupine 
( Hystrix insidiosa , Illig.) ; also some of the smaller 
Edentata, as two species of Armadillo (Dasypus duodecim- 
cinctus , and minutus , Desm.), from South America; the 
long and the short-tailed Manis, the former from India, 
and the latter from Africa ( Manis tetradactyla and penta - 
dactyla , Linn.),—very young specimens of the two, and of 
the three-toed Sloth ( Bradypus didactylus and tridactylus ,
