The species of the genus Eudynamis have remained in so much confusion, partly in con- 

 sequence of the males being clothed in a uniform black garb, while the females and youno- males 

 assume a spotted and barred or otherwise variegated plumage, that I avail myself of this 

 opportunity to offer a sketch of the group. It must be remembered that the adult males are only 

 to be distinguished specifically by their respective dimensions, the relative proportions of tlieir 

 dimensions, and by the form, and in two, if not in more instances, by the colour of the bill. 

 Perhaps in some species the practised eye may safely rely on the nature of the iridescent hues of 

 the plumage. But it is in the colouring, and its distribution, of the young birds and adult 

 females that the most distinct and palpable difference prevails. A superficial observer mi"ht 

 for instance, confound the adult males of E. honorata (L.) and E. ransomi, Bp., but never the 

 females and young birds.
