Of this form I luive seen but the one sj>eciineu of known locality de- 

 scribed above. One of the alleged types of Myothcra (iitalis Laeii. in the 

 nniseum of the lioston Society of Xatural ITistoiy (Lafresnaye collec- 

 tion, Xo. 505-) is apparently referable to this ibrin, though I have uot 

 been able to compare it with Guiana specimens, having retuined it 

 before the one described above was received. The entire belly is dull 

 white, and the breast and sides very jiale brownish gray, without any 

 olive tinge, while the under tail coverts are bright tawny. Its meas. 

 urenients are as follows: Wing, 3.G5; tail, li.OO; exposed culnien, 0.80; 

 tarsus, 1.35; middle toe, 0.82.

Sp. chak. — Intermediate in coloration between F. crismlis and F. 

 Jioffnianni; agreeing with the former in the darker ]>ileum, without 

 rusty on forehead; more restiicted rusty color on side of neck, etc., and 

 purer gray under parts, but differing in much darker coloration (espe- 

 cially lower parts), more intense rufescent color of sides of neck, and 

 smaller (sometimes almost obsolete) wliite loral spot. 



Adult male (Type a^o. 50315, American Museum of Natural History, 

 Priucetown, Trinidad, March 24, 1893, Frank M. Chapnum).— Feathers 

 of ])ileuni dull black centrally, broadly margined Avith sepia-brown, 

 producing a distinctly scaled appearance; rest of upper jjarts clear 

 bistre brown, deepening into Vandyke brown on secondaries and 

 brightening into burnt-umber on upper tail coverts. Lores, orbital 

 region (bordering even the posterior margin of naked postocular space), 

 cheeks, ear coverts (except terminal portion), chin, throat, and fore 

 neck, deep black, the first with a small central spot of white; sides of 

 head and neck immediately posterior to the black area, rusty brown or 

 burnt-umber. Chest dull deep slate (!oh)r; sides and iianks similar but 

 somewhat paler, the belly still paler, though not approaching white, 

 even on the lower portion; under tail coverts entirely clear cinnamon- 

 rufous. Bill wholly deep black; legs and feet dark horn color. Total 

 length (skin), 6.S5; wing, 3.G0; tail, 2.32; exposed culmeu, 0.75; tarsus, 

 1.25; middle toe, 0.72,
