Part I. January—April. 1848. 8vo. 
WE hail with hearty welcome this most noble addition to the illus- 
trated periodical zoological works of our country, and hope that it 
may meet with that liberal encouragement which will induce Mr. — 
Mitchell, the able Secretary to the Zoological Society, to persevere 
in its publication. It is really a very handsome work, and indepen- 
dently of its scientific value, we must say that to the general lover 
of the works of an allwise Creator, this book must prove singularly 
pleasing. There is a very happy selection of subjects—something to 
please everybody. 
Mammalia are represented in 
Galidictis vittata, J. E. Gray, well drawn and lithographed by Mr. B. 
W.Hawkins. This animal belongs to the same family as the weasels, 
and is described by Mr. Gray from a specimen in the British Mu- 
seum, now s0 rich in its collection of mammalia. = 
Ptilocercus Lowii, J. E. Gray, drawn and lithographed by Mr. Wolf, 
A very beautiful and singular insectivorous quadruped, organized for — 
an arboreal life by its singular pen-shaped tail, with its two vanes, so — 
suited to balance the little creature ; it was discovered by Mr. Hugh 
Low, Colonial Secretary, Borneo, in the woods of that island; we 
hope the enterprising Secretary of the Zoological Society may suc- 
ceed in getting from Borneu live specimens of this and other zoolo- 
gical productions of the Indian Archipelago. 
Of Birds there are figured 
Coracopsis ? personata, G. R, Gray, a fine new species of Parrot, 
now in the noble collection of the Earl of Derby, President of the 
Zoological Society; it is figured by Mr. B. W. Hawkins.—Trochilus 
(Heliangelus) Mavors, Gould. Mr. Richter has figured this and the 
next plate (our favourite) of these ‘‘ children or messengers of the 
sun,” assome one has pleasingly named the Humming-bird,—Trochilus 
(Helianthea) Eos, Gould, a most gorgeous bird, and most admirably
