TURBO ANTSHRIKE. 
Adult male——Head and neck, above and laterally, black, each 
feather with a conspicuous mesial guttate streak of buffy white: 
under parts, including chin and throat, dull slate-gray, similarly 
but more broadly streaked, as far back as the lower abdomen, where 
the streaks become obsolete and the ground color paler and more 
buffy gray; under tail-coverts cinnamon with narrow shaft-streaks 
of paler; thighs deeper cinnamon, or russet; under wing-coverts and 
broad edgings to inner webs of primaries deep cinnamon-buff; back 
and scapulars tawny-chestnut, changing on rump to a paler and 
duller, more fulvous, hue; wings ‘and tail clear chestnut; length 
(skin), about 1.45; wing, 75; tail, 57; exposed culmen (tip of bill 
broken off); tarsus, 25; middle toe, 15. 
Northwestern Colombia (Turbo), near eastern extremity of Isthmus 
of Panama. 
This very distinct species is very unlike any other known to me. 
It is about the size of T. palliatus (Lichtenstein), and has the back, 
wings, and tail similar in color, but has the pileum, hindneck, and 
under parts conspicuously streaked with white instead of having the 
pileum plain black and under parts barred with white, the ground 
color of the under parts moreover being gray instead of black. There 
is a closer resemblance in coloration to Berlepschia rikeri (belonging 
@ According to Sclater, Cat. Birds Brit. Mus., xv, 1890, 211. I have seen only Colom- 
bian examples, however, and the species is omitted from the Biologia Centrali- 
Americana. 
b The type of Thamnophilus tenuifasciatus has been carefully examined and com- 
pared with specimens of T. muitistriatus, with the result that it proves to be very 
distinct from the latter. If not a synonym of T. tenuipunctatus Lafresnaye (which J 
have not seen) it must stand as a distinct form.
