144 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.41. 



Female: 1 Wing, 86-89.5 (88); tail, 47.5; exposed culmen, 17-19.5 

 (18); tarsus, 16; middle toe, 11-11.5 (11.3). 



Type-locality. — Jaltipan, Vera Cruz, Mexico. 



GeograpMcal distribution. — Southeastern Vera Cruz, Mexico : north- 

 west to Tlacot alp am; east to Jaltipan; and south to Pasa Nueva. 



This new race may be distinguished from Dryohates scalaris parvus, 

 of Yucatan, by its decidedly lighter upper parts — the black bars 

 narrower, the white ones broader; much narrower postocular and 

 malar stripes, the latter not reaching the bill; smaller or absent 

 black markings on outer vane of outermost long rectrix; darker 

 lower surface; and less heavily spotted sides of breast and body. It 

 differs from Dryohates scalaris hairdi, of Hidalgo, in being very much 

 smaller; in having the upper parts decidedly lighter, the black bars 

 being narrower; black bars on tail not so wide; black markings on 

 outer web of outermost long rectrix smaller; postocular and malar 

 stripes much narrower, the latter not reaching the bill; lower surface 

 paler, spotted instead of streaked, and less heavily thus marked, with 

 black. 



Of this race we have seen seven examples, representing the following 

 Mexican locahties: 



Vera Cruz. — Jaltipan; Tlacotalpam; Pasa Nueva. 



DRYOBATES SCALARIS PERCUS, new subspecies. 



Chars, suhsp. — Similar to Dryohates scalaris ridgwayi, but larger; 

 lower surface paler and much more heavily spotted with black; upper 

 parts darker, the wliite bars much narrower, the black bars wider; 

 postocular and malar stripes somewhat broader; spots of black on 

 white portion of outer vane of outermost long rectrix (the second) 

 averaging larger, inclining sometunes to bars. 



Description. — Type, adult male. No. 193906, U.S.N.M., Biological 

 Survey collection; Comitan, Chiapas, Mexico, April 15, 1904; E. W. 

 Nelson and E. A. Goldman. Crown and nape black, the feathers of 

 the former subterminally dull white, terminally 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; remainder 

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

 with white — these white bars narrower than the black interspaces; 

 tail black, the three outer pairs of feathers, including the dwarfed 

 exterior one, much barred with dull wliite, excepting on basal portion 

 of inner webs of the second and third, the black interspaces on the 

 outer vanes often reduced to spots, particularly on basal part; the 

 fourth pair irregularly and broadly margined with white on outer 

 vanes; wings black, with numerous spots of white, which, on tertials, 

 become fairly well-defined bars; sides of head and neck deep brownish
