Notes on Hicniming- Birds. 427 



under tail-coverts are almost pure white, and all the feathers 

 of the upper parts have pale buff edges and a narrow dark 

 subterniinal line. This last character is generally a sign of 

 immaturity, but tiie four birds that I have studied are evidently 

 fully adult specimens. The same character, though the edges 

 are there not pale buff, but rich rusty buff, is found in the 

 West-Ecuadorian P. berlepschi, E. & CI. Hart. (Nov. Zool. 

 i. p. 56), of which I have now seen some more skins. 



In P. baroni the chin and middle of the throat is rusty 

 buff, the sides of the throat rather dark : " maxilla black, 

 mandible bright orange-red with black tips ^^ {Baron). 

 P. baroni differs from P. super ciliosus moorei in having the 

 tips of the outer rectrices bordered with pure white, in the 

 chin and middle of the throat being clear rusty buff, all the 

 feathers of the back having buff edges, and in the colour of 

 the abdomen, but on the whole is, perhaps, nearer related to 

 it than to P. longirostris. The measurements of the type of 

 P. baroni, from Naranjal, are as follows : — Total length 

 about 150 mm., wing 58 (59 and 60 in the others), central 

 rectrices 68, lateral 23, exposed culmen 39. 



P. bolivianus is puzzliugly near to P. longirostris, but 

 unless future explorations shall show that it occurs in the 

 long stretch of intervening countries it must be kept as a 

 species, otherwise I should treat it as a mere subspecies. 



P. apheles, Heine, J. f . O. 1884, p. 235, is, according to 

 Berlepsch, probably a distinct species, closely allied to his 

 P. nattereri, but differing in its pure black and broad sub- 

 apical band to the outer rectrices, and in its shorter wings. 

 In the ' Catalogue of Birds ' I do not find it mentioned. 



P. garleppn, Boucard, has been described from a duplicate 

 specimen received from Count Berlepsch, who has a series 

 from the same locality, and the Count informs me that he 

 cannot distinguish his Bolivian skins from the typical 

 P. pretrii from Brazil. It may therefore be dismissed 

 without the slightest hesitation. 



P. gounellei, Boucard, is a good species, nearest allied to 

 P. squalidus, and not to P. nattereri, Berlepsch, which is 

 also a good species and not a form of P. pretrii. The most
