Adult male (type, No. 115041, U. S. Nat. Mus., Naranjo, Cartago, Costa 

 Rica, August, 1886, J. C. Zeledon).— Pileum dusky sepia brown, each 

 feather with a very distinct mesial streak of pale dull buffy, the ground 

 color gradually changing on occiput, hind-neck and back into raw-um- 

 ber, tinged with rusty, the streaks at the same time becoming narrower 

 until they disappear altogether about the middle of the upper back; 

 lower back, rump, and upper tail-coverts light reddish chestnut; remiges 

 and rectrices rather deeper, or clear chestnut, the shafts of the latter 

 becoming blackish basally; wing-coverts and outer webs of primaries 

 and their coverts light raw-umber. Sides of head streaked with pale 

 dull buffy and dark sepia, the latter prevailing on malar region, the 

 former immediately above, forming two ill-defined, rather broad, stripes ; 

 chin and upper throat plain pale dull buffy ; rest of lower parts raw- 

 umber, tinged with rusty or tawny, the chest, upper breast, and sides 

 of neck rather broadly and very distinctly streaked with very pale 

 buffy, the other lower parts much more narrowly and indistinctly 

 streaked with the same; middle portion of lower belly marked with a 

 few transverse spots of blackish, arrauged transversely, but not form- 

 ing continuous bars ; under wing-coverts light ochraceous, transversely 

 spotted with blackish, these spots on both webs of the feathers, but 

 those of opposite webs separated by a median space of ochraceous. 

 Bill light grayish horn-color, darker basally; feet dusky horn-color; 

 "iris dark." Length (skin), 10.90; wing (quills woru at tips and some 

 of them moulting), 5.70; tail (middle feathers not full grown), 5.10; cul-

Immature female (No. 2006, coll. Costa Rica National Museum, same 

 locality, etc.).— Pileum dull black, changing to bistre-brown on occiput, 

 each feather marked with a distinct mesial streak of pale brownish buff; 

 hind-neck and upper back lighter and clearer brown* than occiput, but 

 similarly streaked, though the streaks become much narrower on the 

 back; scapulars and lesser wing coverts similar in color to the back, 

 but without streaks ; middle and greater coverts similar, but tinged 

 with rusty; remiges clear, rather light, chestnut, the primaries edged 

 with light bistre ; primary coverts light bistre, with median portion 



* Intermediate between the bistre and ruuminy-brown of my "Nomenclature of
