In the department of Ornithology the acquisitions are more 

 numerous and valuable, including many species hitherto unde- 

 scribed, and one type of form which is altogether new to the 

 Zoologist. We shall enumerate the species in the order in which 

 they are described and figured, interspersing the list with occa- 

 sional observations, and with the characters assigned to such of 

 the birds as are new.

 latter the Vanga roux of M. Vieillot. It is a true Thamnophilus^ 

 and may be regarded as almost typical of that genus in the charac-

 the Zoological Journal, under the name of Thamnophilus Vigor siij 

 and both the male and female birds were figured in the Supple- 

 mentary Plates. 



Barita Tibken^ Cuv. ; a well-known species ; being the Coracias
