bars are decidedly narrower; less broad black tail-bars, on the 

 outermost long rectrix particularly; the lower surface of body much 

 lighter, more heavily marked on breast and sides, spotted, instead 

 of streaked, with black. It may be distinguished from Dryohates 

 scalaris scalaris by its smaller size, rather darker upper surface, the 

 black bars being somewhat broader, the white bars narrower; wider 

 postocular and malar stripes, the latter extending to the bill; and 

 paler under parts, more heavily spotted with black. 



So far as known, this race is confined to northern Yucatan, but 

 its range may be extended by future explorations. 



The bird described by Cassin as Picus vagatus,^ from "Mexico," 

 is the same as the Yucatan race. This Mr. Witmcr Stone has kindly 

 determined by an examination of the type in the collection of the 

 Philadelphia Academy of Sciences and a comparison with typical 

 examples of Drijohates scalaris ridgwayi and Dryohates scalaris 'parvus. 

 Mr. Stone furnishes the following measurements of the type: Wing, 

 88; tail, 54; exposed culmen, 18; tarsus, J4. 5 mm. 



Specimens examined, 24, from Mexican localities as under: 



Yucatan. — La Vega; Chichen Itza; Progreso; Merida; Temax: San 

 Felipe; Tekanto; west of Tunkas. 



DRYOBATES SCALARIS LEUCOPTILURUS, new subspecies. 



Cliars. suhsp. — Like Dryohates scalaris parvus, but still smaller; 

 lower surface much darker, but somewhat less heavily spotted; 

 outer webs of second (the first long) pair of rectrices without bars 

 basally; black bars on upper parts rather narrower and more irregu- 

 lar; primary coverts with rather less white on outer webs. 



Description. — Type, adult male, No. 252.54, Carnegie Museum; 

 Pine Ridge, near Manatee Lagoon, British Honduras; October 26, 

 1905; Morton E. Peck. CrowTi and nape black, the feathers of the 

 former subterminally dull white, termmally poppy red, this pro- 

 ducing a mottled effect on the top of the head, but merging into 

 a solid band of red on the occiput and anterior hind neck; remaining 

 upper parts black, all, excepting the superior tail-coverts, barred 

 with white, these white bars somewhat wider than the black inter- 

 spaces; tail black, the three outer pairs of feathers, including the 

 dwarfed outermost one, barred with white except on basal portion 

 of inner webs of the second and third, but the outer vanes of the 

 second (the first long pair) and third almost wholly white basally; 

 the fourth pair largely white on distal half of outer vanes; wings 

 black, with numerous spots of white, which, on the tertials and 

 some of the inner long wing-coverts, become fairly well-defined bars; 

 sides of head and neck pale smoky brownish; a broad postocular 

 and a malar stripe of black, which meet on the side of the neck;
