I agree with Mr. Cassin (/. s, c.) tliat the distinctness of the 

 Brazilian form of this bird from that of the Guianan and 

 Amazonian districts is rather questionable. But in the series 

 of seventeen specimens before me, all of the latter series (C. 

 affinis) agree in having the plumage in both sexes of a deeper 

 and more shining black, and in the males there is the addi- 

 tional character of the larger and thicker bill, specially alluded 

 to by Bonaparte (C. K. xxxvii. p. 833). 



It may be noted that Linnaeus based his Oriolus hamor- 

 rhous mainly on Brisson^s Cassicus ruber, which = Cassicus 

 affinis. Luckily, however, Linnaeus put Brazil first in his list of 

 localities ; so I think (as he comprehended both forms under 

 one name) we are justified in following the general practice 

 of retaining the name hcemorrhous for the Brazilian form, and 

 calling the Guianan form affinis.
