148 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.41. 



wing-coverts, become well-defined bars; sides of head and neck deep 

 brownish white; a black postocular and a black malar stripe, which 

 meet on the side of the neck, the malar stripe, however, obsolete 

 anteriorly; nasal tufts and lower surface light smoky brown, the 

 chin, abdomen, flanks, and crissum wliitish; sides and middle of 

 breast, and sides of body heavily spotted with black; the flanks and 

 crissum barred with the same; hning of wing brownish white, spotted 

 with black. 



Measurements. — Male: ^ Wing, 92 mm.; tail, 48.5; exposed cul- 

 men, 18.8; tarsus, 15.5; middle toe, 11. 



Type-locality. — La Salada, Michoacan, Mexico. 



Geographical distribution. — Southern Mexico: west to La Salada, 

 central western Michoacan; north to Chietla, southwestern Puebla; 

 east to Tlacolula and Oaxaca, west central Oaxaca; south to Sola, 

 southwestern Oaxaca, and Amula, central Guerrero. 



This form is supei-ficially much like Dryohates scalaris sinaloensis, 

 but differs in its smaller size; spotted instead of streaked breast and 

 sides, these parts more heavUy marked; lighter under surface; and 

 somewhat less wliite on outer webs of primary coverts. 



Curiously enough, this new form much more closely resembles 

 Dryohates scalaris leucoptilurus from British Honduras, and Dryohates 

 scalaris sinaloensis, from Sinaloa, Mexico, than it does any of the 

 geographically adjoining races. Although only the type has been 

 available for examination in this connection, tliis example is so 

 different from Dryohates scalaris centropMlus, from Jahsco,^ Drijohates 

 s. hairdi from Hidalgo and Mexico, Dryohates scalaris ridgwayi, from 

 Vera Cruz, and Dryohates scalaris percus, from Chiapas, that it 

 deserves separation. Another specimen, from Chietla, Puebla, was 

 examined by Mr. Ridgway a number of years ago,^ and he is now 

 convinced that it should be referred to this race, an impression borne 

 out by liis printed remarlcs on tliis bird.* The present species 

 (Dryohates scalaris) has been recorded from localities in the States of 

 Guerrero and Oaxaca,^ and these States, without much doubt, should 

 be included in the range of this form.

Chars, suhsp. — Resembling Dryohates scalaris azelus, but decidedly 

 larger; under surface paler, and much less heavily spotted, some- 

 times streaked, with black; postocular and malar stripes wider;
