of pileum sli(n*t; anteorbital and ]:»ostociilar regions (.1. rufigula) or 

 suborbital, postocular, and lower portion of loral regions {A. hicolor 

 and allies) naked; latero-frontal feathers short and erect (denser, 

 more plush-like in A. rufigula). 



Coloration. — Plain bro^vn or olive, with throat tawny ( r rufescent, 

 or with throat and median under parts white ;^' sexes alike or nearly so. 



Range. — Honduras to Amazon Valley and Cayenne. (Eleven or 

 more species recognized.'') 



KKY TO THE SPECIES OK ANOPLOPS. 



a. Underparts l>rown (no white), becoming tawny or rufouw on throat and auricular 

 region. (Britisli Guiana to lower Amazon Valley.) 



Anoplops rufigula (extralimital).c 

 aa. Underparts liroadly white medially, including throat; auricular region black or 

 dusky. 

 h. Above bright tawny-chestnut, more rufescent on forehead, 

 c. Sides and flanks chestnut or rufous-chestnut. (Colombia.) 



Anoplops ruficeps (exlralimital').<^ 

 cc. Sides and flanks olive-lirown, becoming slate-grayish next to white of breast, 

 etc. (Colombia and upjier Amazon Valley.) 



Anoplops leucaspis (extralimital).c 

 hh. Above vandyke brown, not more rufescent on forehead, 

 c. Forehead and postauricular regions slate color. (Eastern PanamA.) 



Anoplops bicolor (p. 132). 



cc. Forehead and postauricular region Ijrown, like pileum, etc. (^^'estern Pan- 



arad to eastern Honduras.) Anoplops olivascens (p. 132). 



o A. /?o?!/ZflYa(Sclater and Salvin), a species which I have not seen, has black and 

 ochraceous lunulations on the back, and whitish spots on inner webs of rectrices. 



& Of these I have not seen the follo'sving: A. lunulata (Sclater and Salvin), A. 

 salvini (Berlepsch), A. griseiventris (Pelzeln), A. cristata (Pelzeln), A. berlcpschi Sneth- 

 lage, A. hoffmannsi Hellmayr, A. pallidus Cherrie, and A. melanosticta (Sclater 

 and Sah-in). Anoplops lunulata differs from A. bicolor and its allies in more 

 slender bill, much narrower and more broadly operculate nostrils, and very much 

 denser aa well as longer feathering of the loral region. The style of coloration ia 

 somewhat different, there being no white on the under parts, the chin and throat 

 being rufous-tawny and the under parta of the body brown. The naked skin on 

 sides of head, together with the legs and feet, are yellow, instead of blue and dusky 

 horn color, respectively, as in A. bicolor, etc.
