196 PROCEEDINGS OP THE ACADEMY OP 



Hab. Lower California. Spec, in Mus. Acad. Philada. 



Much resembling P. scalaris, but with the bill and feet stouter and the bill 

 longer, white spots on the head larger and the black stripes on the back ra- 

 ther narrower. 



Scarcely distinguishable from P. scalaris and hardly a species, but presents 

 differences which may be constant as stated above. This bird has only been 

 found in Lower California. 



4. Picus Bairdii, Sclater. 



Picus Bairdii, Sclater. Malh., Mon. i. p. 118. 

 Malh. Mon. pi. xxvii. figs. 7, 8. Baird, B. of N. A. pi. xli. fig. 2. 

 Hab. New Mexico, Northern Mexico. Spec, in Mus. Acad. Philada. 

 Generally similar to the last two species but with the white bands on the 

 bach wider than the black bands. Total length about 7 inches, wing 4^, tail 2J 

 inches. 



All specimens from New Mexico and Northern Mexico appear to be this 

 species, and it is that which has heretofore been regarded by the ornitholo- 

 gists of this country as P. scalaris. 



5. Picus Orizaba, nobis. 



Picus scalaris, var. d'Orizaba, Malh. Mon. pi. xxvii. fig. 6. 



Hab. Jalapa, Mexico, Eastern Mexico ? Spec, in Mus. Acad. Philada. 

 Similar to P. Bairdii but smaller, the brownish white stripe immediately 

 below the scarlet of the head, extending over the eye and wider behind the 

 eye than in P. Bairdii. White bands of the back wider than the black bands. 

 Total length 6h inches, wing 4, tail 2J inches. 



Brought from Jalapa commonly, by M. D'Oca and seems to be the represen- 

 tative of this group in Eastern Mexico. There are synonyms usually referred 

 to P. scalaris which may be applicable to one or the other of these birds, but 

 I cannot identify them. 



6. Picr/s vagatus, nobis. 



Much smaller than either of the preceding, though belonging to the same 

 group and especially resembling the two last described above. Male. Head 

 above scarlet, all the feathers being black at base, with small white spots, 

 which are more numerous on the front and vertex, stripes from the base of 

 the lower mandible and behind the eye black, from the base of the upper man- 

 dible and another over and behind the eye sordid or brownish white. Back 

 and exposed surface of quills banded transversely with black and white, which 

 on the back are about equal in width. Wing coverts black, with circular and 

 oblong spots of white, upper tail coverts black. Under parts brownish white, 

 with circular and irregular spots of black more numerous on the breast and 

 sides and forming transverse bands on the flanks. Tail feathers black, two 

 outer feathers on each side with white bands. Quills brownish black, with 

 quadrangular or irregular spots of white on their outer webs, and large circu- 

 lar spots of white on their inner webs. Bill and feet dark, short feathers on 

 the nares fuliginous. 



Total length about 5i inches, wing 3|, tail 2 inches. 



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



Two specimens of this little species are in the Acad. Mus. from the Massena 

 collection, but are unfortunately without labels indicating locality. They are, 

 however, strictly of the same form and generic character as the birds above 

 mentioned, and are probably from Mexico or Central America. This species is 

 easily distinguished from all others of its intimate allies by its much smaller 

 size as above described. It is not larger than Picus minor, Linn. 



3. Genus POLIPICUS, nobis. 

 Belonging to the group Gecinina, G. R. Gray, and allied to the genus Geci-
