Pyrocephalus minimus RIDGWAY, Proc. U. S. Nat. Mus., xn, p. 113, 1890, 

 in text (Chatham Island). 



Range. Chatham Island. 



This species differs from P. nanus in having a shorter wing, the 

 wing not exceeding fifty nine millimeters in length and averaging about 

 fifty seven millimeters, while in P. nanus the wing varies from sixty 

 one to sixty six millimeters averaging about sixty three. We have 

 four adult males : two of them are decidedly orange-red below, much 

 more so than in P. nanus abingdoni; one of the others has less of an 

 orange shade, while the fourth is indistinguishable in color from ordi- 

 nary males of P. nanus. 



We found this species fairly common on Chatham in May, where we 

 took four adult males and two adult females. They were perhaps more 

 plentiful in the upper cultivated parts of the island than elsewhere.
