Herpetologia Mexicana. 401 



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. 

 Tardus 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 : Dracuncuhis for 

 some species of Draco Chamceleopsis, which scarcely differs from 

 Corythophanes of Boie. Lazmanclus, 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, Lcemanctus, Cory- 

 thaeolus, Chamceleopsis, Sceloporus, Phrynosoma, Genhonotas. 



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.
