^ G? /o Vol. 45, pp. 167-168 September 27, 1932 OF THB BIOLOGICAL SOCIETY OF i^ASHINQTPN NEW BIRDS FROM CHIRIQUI PROVINCE, PANAMA. BY M. E. McLELLAN DAVIDSON. A preliminary study of the material resulting from field work conducted on behalf of the California Academy of Sciences in Chiriqui Province, Panama, between 1929 and 1932, reveals the existence of several new birds, three of which are described below. Automolus Xanthippe, sp. nov. Type. — No. 33,220, Collection California Academy of Sciences, adult female; Barriles (4200 feet), Chiriqui, Panama, January 28, 1931; M. E. Davidson. Description. — Forehead, crown, occiput, outer aspect of wing, and central rectrices Bay, in marked contrast to the Raw Umber of the scapulars, interscapulars, and rump ; upper tail-coverts and lateral retrices Chestnut ; feathers of the lores Cinnamon-Buff lightly tipped with black; indistinct supra-auricular stripe inclining to Cinnamon-Brown, auriculars shghtly darker, but with pale Cinnamon-Buff mesial streaks; the Ochraceous-Tawny of the chin and throat passing into Clay Color on the center of the abdomen and into Chestnut on the longer under tail-coverts; sides and flanks Saccardo's Umber; axillars, Hning of wing, and inner margins of remiges Ochraceous-Tawny; maxilla and contiguous area of mandible dark horn color, remainder of mandible pale straw color. Wing, 85.0 mm. ; tail, 77.5; length of culmen, 28.2; depth of bill at gonydial angle, 8.0; tarsus, 26.0; middle toe, 22.5. Remarks. — Only the one specimen of Automolus Xanthippe is extant, but in the coloration of the crown, wing, tail, and throat, as well as in the much heavier bill, and longer tarsus and middle toe, the new species is distinguished from Automolus ochroloemus exsertus, to which it is most nearly aUied. The contrasting wings and back differentiate it from Automolus jumosus. Spodiornis barrilesensis, sp. nov. Type. — No. 33,413, Collection California Academy of Sciences, adult male; Barriles (4500 feet), Chiriqui, Panama, January 28, 1931; M. E. Davidson. 47— Proc. Biol. Soc. Wash., Vol. 45, 1932. (167)
