small size. The bill is flattened, the width at the hase Iteiii^- e([iial 

 to about halt" the length of the exposed culmen. The wing is 

 slightly rounded, the second to the fifth primary-quills longest 

 and the first nearly as long as the second. The tail is S(j[uare at 

 the tip and about equal in length to that of the exposed cuhnon. 

 The tarsus is about equal to the tail (in P. ecaudata) in lengtli, 

 and the hind toe and claw are about equal in length lo the middle

AdaJt. Back, wings, and tail yellowish green; primar^'-coverts 

 unitorm dark brown ; flight-quills blackish brown with gre^n 

 margins on the outer webs and pale edges to tha inner ones; tail- 

 feathers dark brown fringed with green; head and sides of fac** 

 dark ash-grey; tlie short feathers at the base of the bill and 

 surrounding the eye white ; throat and entire under surface 

 silky-white with a tinge of yellow on the flanks, edge of wing, 

 and under wing-coverts, and a wash of ash-grey on the sides of 

 the breast; under surface of quills and lower aspect of tail brown. 



Total length 58 mm., exposed culmen 8, wing 34, tail 12, 

 tarsus 13. 



Tlie bird described was collected on the Bonasika River. 



Having compared the four exam{)les of this bird in tlie 

 McConnell collection with a specimen in the British Museum 

 from Bolivia, which is the type-locality of P. ecaudatus (d\)rb. & 

 Lafr.), I find that they are darker green on the back, darker 

 grey on the crown of the head and face, and inclining to grey on 

 the under surface. It differs also in having the lower mandible 

 black and the feet much darker than the Bolivian bird.
