This statement is, however, to be regarded as founded strictly on the views 

 of M. Malherbe, in a few particulars of which I have the misfortune to differ 

 from him. Making deductions for species given by him as valid, which are 

 very probably identical with others, (such as Picus Martina;, Aud., Phillipsii, 

 Aud. and some others) and additions for species recently described and not 

 included by M. Malherbe, aad also a few species given by him as synonyms, 

 but which appear to me to be properly regarded as distinct, I have deter- 

 mined 236 species of Woodpeckers in the Academy Museum. 



2. Picas scalaris, Wagler. 



Of the birds regarded as this species or varieties of it, or near allies, there 

 seem to me to be several species, quite distinct from each other and probably 

 inhabiting separate regions of North America. 



1. Picus Nuttallii, Gambel. 



Malh. Mon. pi. xxiv. figs. 5, 6, 7. Baird, B. of N. A. pi. xli. fig. 1. 

 Hob. California. Spec, in Mus. Acad. Philada. 



In this species there is in the adult male a wide frontal and coronal space 

 which is frequently clear black, but generally with the feathers having long 

 narrow spots of white at their tips. Immediately succeeding the scarlet of 

 the occiput is a narrow band of white and then a wide band of black. The 

 back is very distinctly banded with black and white the black bands being the 

 wider. The two black stripes from the base of the lower mandible and from 

 behind the eye unite and form a large black space on the side of the neck. 



This is a readily defined and easily recognized species and the largest of this 

 group. It appears to be restricted to California. 



2. Picus scalaeis, Wagler. 



Malh. Mon. pi. xxvii. figs. 1, 2, 3, 4, 5. 



Hab. Southern Mexico ? Spec, in Mus. Acad. Philada. 

 Plumage of the head above tipped with scarlet and with small medial or 

 subterminal spots of white. Back with the transverse bands of black and 

 white clearly defined but narrower and more numerous than in the preceding, 

 but with the black bands the wider. Smaller than the above and easily distin- 

 guished from that species. 



3. Picus lucasaxus, Xantus. 



Picus lucasanus, Xantus, Proc. Acad. Philada., 1859, pp. 298, 302, (not 

 figured).
