The four known species oi Pi/Jile may be distingnislieJ liy the following key. 



A. Sides of the head (except a narrow rim round the eye) as well as chin and 



upper part of the throat thickly covered with deep black feathers. Fore- 

 head and superciliaries deep black. Pileum and crest with narrow, 

 liair-like blackish shaft-lines. Plumage dark brown, glossed with {mrjile. 

 Foreneck and breast strongly edged with white. . . . P.jacutiii[/a (Spix). 



B. Lores, superciliary — and eye-region, cheeks and the whole throat naked, 



only a broad malar stripe being feathered. Forehead never black. 



a. Plumage glossed with green. Pileum and crest nniform huffy white, 



or with hair-like blackish shaft-lines ... P. cumanensis (Jacqu.). 

 h. Plumage glossed with purple. Pileum and crest with broad blackish 

 brown stripes. 



i'. White margins of the crest-feathers broader. Median series of 

 ujjper wing-coverts purplish brown, with a white margin on 

 each side ; greater series with a narrow white margin along the 



second third of the outer web 1'. cujiihi (Pelz.). 



b-. Crest-feathers blackish brown with only very narrow white edges. 

 Median series of upper wiug-coverts pure white, except the 

 extreme base and a distinct blackish brown tip ; greater series 

 on the outer webs white to the shaft excej)t the tip. 



P. pipile (Jaciiu.). 



101. Crypturus soui (Ilerm.) (subsj). ?) 



Tinamiis sunt Ilcrmauu, Tab. Aff. Aniiii. 1783. pp. 11)4, 255 (ex Daubeuton, I'l. cid. 8"J'.l. — Oii/iiiiii). 

 Cnjpiuran pileidus auct. 



One ? ad. and d juv. from Ca])aro, April ; two ? ¥ ad. and one S juv. from 

 Chaguanas, -June and January. 



Tlie adult birds agree best with others from the Orinoco delta (Guauoco), wiiile 

 those from Cumana and British Guiana, as a rule, are rather lighter and brighter 

 beneath. A large series from different parts of its range is reqirircd for defining 

 the various geographical races into which C. soui is doubtless separable.
