of Ridgway can be recognised, especially it' compared with .1/. niyriceps of Ecuador. 

 Ridgway liimself only created the name Kribates as a subgeneric term, but does 

 not use it.

We have this species from the following islands : Chatham, Charles, Gardner, 

 Hood, Barringtoii, James, Duncan, Indefatigable, Jervis, Albemarle, Narborough, 

 Abingdon and Bindloe, and one caught on the vessel off Wenman Island. 



There are no differences between any of these, except that those from Chatham 

 seem to have the wing about ~ — 4 mm. shorter. As, however, we have only one 

 fresh skin and two from spirits (the type in the British Museum being of donbtfnl 

 origin), we cannot maintain that this character is of specific or snbspecific value. 

 A larger series would be necessary to show the value of this peculiarity. 



The femdlc is considerably smaller than the mfi/(', with the wing about Ti mm. 

 shorter. There is generally a little less cinnamon-rufous on the inner webs of the 

 rectrices, but other differences in colour are not to be seen. 



Genus PYROCEPHALUS Gould. 



Pyroceplmlii.1, Gould in Voy. Beayle, Zool. III. Birds, p. 44 (1841) ; Sclater, Git. B. Brit. Mus. XIV. 

 p. '211. 



This genus is most closely allied to Afi/ioli/us, from which it hardly differs in 

 structure, except by its somewhat more elongated bill and less developed rictal 

 bristles, but the coloration of the ma/e.i makes all its members very consincuous. 



The genus is absent from the "West Indies, but spread over the whole of South 

 America, from Southern Florida through Central America to Argentina, and is 

 frequent on the Galapagos Islands. 



Only two forms cau be distinguished in the Gala^iagos Archipelago, the forms 

 separated by Ridgway on account of certain alleged differences in colour not being 

 recognisable.

This sjiecies differs from J', rubineus of South America and P. ine.ricantis of 

 Central America in its much smaller size and the coloration of the/fi/ifili', which is 

 broadly striated on the breast in P. riibinem and P. me.vicami.i, but only faintly or 

 not at all distinctly streaked on the breast in P. mimis. 



The type of /'. wnni.s is only known to have come from the " Galapagos 

 Islands," but the exact island where it was procured is not known. Ridgway 

 restricts its habitat to James Island. From this island we have twenty-four skins, 

 about half of them being vkiIi-h. From Indefatigable Island we have thirty-six
