rous species of various forms, and enabling us to distinguisli at 

 once in other species resemblances of analogy from those of affi- 

 nity : so true is it that in the smallest natural groups of orga-

 when carefully sought for, which exhibit themselves so obviously 

 in the larger divisions of the Kingdom of Nature.

 Parti. 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 so 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 Borneo 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," as some one has pleasingly named the Humming-bird, — Trochilus 

 (Helianthea) Eos, Gould, a most gorgeous bird, and most admirably
