ARCTIC THREE-TOED WOODPECKER. 



{Picus (Apternus) arcticus, Swains. North. Zool. ii. p. 313. pi. 57. 

 Picus tridactylus, Bonap. and Nutt. Man. Orn. i. p. 378.) 



Sp. Charact. — Above glossy black, with white spots on the quills 

 only ; beneath white ; sides lineated with black ; crown saffron- 

 yellow. 



What we have said under this species applies exclusively 

 to the preceding with which it has till now been confound- 

 ed. The present is a larger bird, with the bill longer in 

 proportion and more depressed. It has been seen only on 

 the eastern declivity of the Rocky Mountains, where the 

 preceding is also found. 



RED-SHAFTED WOODPECKER. 



(Picus (CoLAPTEs) Mexicanus, Nobis. Colaptes Mexicamis, Swains. 

 North. Zool. ii. p. 315. Picus Cafer^ Lath. Ind. Colaptes colla- 

 ris, Vigors. Zool. Journ. 15. p. 354.) 



Sp. Charact. — Shafts of nearly all the feathers reddish-orange; 

 maxillary stripe blood-red ; body beneath vinaceous. The rest of 

 the plumage generally as in P. auratus. 



This species, so similar to P. auratus in size and the 

 general colors and markings of the plumage, inhabits Mex- 

 ico, New California, and the coast of the Pacific for some 

 distance to the northward of the Columbia River.
