Remark. This and the preceding three species vary greatly in 

 plumage. No. 53 is in structure a miniature of No. 52 ; No. 54 is larger 

 than No. 53, but less robust ; and the present species, with about the 

 same linear dimensions as No. 54, is again of more feeble conformation. 

 A practised eye readily distinguishes either in any phase of colouring.
