ant bird in the work, on account of its being given as altogether new, 
is Turdus Whitei. It is difficult to give a decided opinion without 
having seen the specimen, but we think it will prove ultimately to 
be a missel-thrush in immature or in some variety of plumage. 
Turdus varius may be known in all its states by the deep velvety 
black of the axillary feathers.*

It is quite unnecessary to say more, than that the execution of 
the work fully justifies this ample title. The genera in the table 
are carefully characterized, and the plan is convenient and easily 
understood, though not so natural in the arrangement of the groups 
as might be. 
The descriptions of the species are full, the plates very accurate, 
and beautifully coloured* 
The work contains the following new genera : Dracunculus for 
some species of Draco Chamceleopsis, wjiich scarcely differs from 
Corythophanes of Boie. Lcemanclus, very like Polychrus, but with- 
out any pores, and differing in the comparative length of the toes. 
Strombilurus, like Tropedurus, but with a keeled back, and larger 
keeled scales. Platydaclylus , with slender toes, only dilated at the 
end. 
The plates represent the genera Heloderma, Lcemanclus, Cory- 
thceolus, Chamceleopsis, Sceloporus, Phrynosoma, Genhonotus. 
It may be remarked, that Phyllurus is rather a sub-genus of Go- 
niodactylus than of Gunynodactylus, as its toes are compressed and 
arched, like the typical species of that genus. J. E. G.
