vinons-reil. None of my fifteen specimens from more sonthern localities sliow any 

 ajiproacb to those from Parii. A male from British Guiana, however, is nearly as 

 dark below as southern examples, and therefore I cannot believe that the birds from 

 Para constitnte a different race. I think the difference may be due to age, for 

 both the Para specimens seem to be not quite adult.

These specimens are practically identical witli otiiers from Cayenne and 

 British Guiana. 



The nomenclature of the Ca/. Binla: .\i. p. 324 if. is wrong. The bird there 

 named ('. ciffiitis ought to be called G. I/cu'morrlious, while the form of the Brazilian 

 forest region must bear tlie name C. h. ajiliioieti Berlp. Brisson expressly states 

 that the bird described was from Cayenne, and Linue's name is therefore strictly 

 referable to the northern subspecies.

 It differs from a large series of .S'. mnbii'tta in lacking the deep cliestnut-rnfous 

 colour on the rump, which is dark olive-brown like the back, and in having the 

 forehead and the sides of the head strongly washed with rufous (instead of dnll 

 olive-livowii). The throat, too, is purer white, and the colour of the breast and 

 abdomen of a more rufous tint.

This specimen agrees with the typo, but is slightly smaller. The examples 

 collected by Natterer near Borba and Barra do Rio Negro belong likewise to this 

 subspecies. 



The form of the Lower Amazon differs from the typical one in its dark 

 greyish brown (not pale rufous) crown, nn<l in having flic back of a dull 

 olive-brown.
