LOWER MAMMAL GALLERY. 
Lower The lower Mammal gallery is entered from the western 
eSiery*^ corridor of the central hall. Together with the adjacent 
corridor it contains the greater part of the exhibited series of 
recent Mammals, with the exception of the Cetacea, Sirenia, and 
Proboscidea; the orders Primates, Chiroptera, and Insectivora 
being in the upper gallery. As two special guides* are devoted 
to these galleries, a very brief notice will serve on this occasion. 
Both stuffed specimens and skulls and skeletons are exhibited, 
although the former constitute by far the greater portion of 
the series. A few remains of extinct types, or plaster repro- 
duction of the same, are introduced here and there ; and 
photographs of living animals are hung on the walls, where 
Fig. 33. — The Platypus or Duck-bill (Ornithorhynchus anatinus). 
will also be found some instructive series showing the modi- 
fications assumed by the teeth of cerfcain groups. Wherever 
possible, the horns and antlers of the ..Euminants, as well as 
the horns of the Ehinoceroses, are placed in juxtaposition to 
the animals to which they respectively belong. 
The series commences on the right side of the gallery with 
the lowest forms. Down the middle is a row of large Mammals, 
comprising various Deer, Seals, and Pthinoceroses. On the right 
of the entrance a small case contains the Platypus or Duck-bill 
(fig. 33) and Echidnas of Australia and New Guinea, which lay 
eggs, and are the lowest of all living Mammals. In the adjacent 
bay are the Marsupials, such as the Kangaroos, Phalangers,
