in New Guinea and the adjacent Islands. They 
vary greatly in size from that of a rabbit to the 
height of a man, and are all vegetable feeders. In 
the female the pouch is highly developed, and the 
young one seeks its shelter long after it has become 
able to run or rather bound by the side of its 
mother. The pretty little head, peeping out of its 
warm and soft retreat, 1s a very interesting sight, and 
one often to be witnessed in the gardens of the 
Zoological Society, where several species have bred. 
The third sub-class) EUTHERIA, contains the 
whole of the remaining groups of Mammals, which 
greatly as they may differ from each other in appear- 
ance, mode of life, and other respects, all possess one 
feature in common, viz., “‘the presence of an allantoic 
placenta, by means of which the fcetus is nourished 
within the uterus of the mother,” and hence they have 
_ been called Placentalia. ‘The nine orders into which 
this great sub-class is divided have already been 
enumerated at Z. 144, and will only be again referred 
to as the specimens illustrating them are passed in 
review. 
' The first order is that of EDENTATA, comprising 
the Sloths, Ant-eaters, Armadillos, Pangolins or 
Scaly Anteaters, and the Ard-varks or African 
Ant-eaters. Of these five families the first three are 
inhabitants of the New and the last two of the Old 
World. 
Of the Sloths and Great Ant-eaters we have no 
representatives, but of the Dasypopip@ or Armadillos, 
and the Manip@, Pangolins or Scaly Ant-eaters, we 
possess several specimens. 
Some twenty species of Armadillo are recognised. 
They are found only in the warmer parts of America, — 
the former home of their gigantic predecessors, the 
extinct Glyptodon, ‘Their food is very variable, con-
