a great amount of rufous on the outer webs, and a slight 

 rufous suffusion on the inner web before the white tips. In 

 true Fh. longuemarei there is no, or but little, rufous tint 

 on the submedian tail-feathers. 



The outer tail-feathers in Ph. nattereri possess very long 

 rufous tips ; in Ph. longuemarei there is a narrow white 

 or rufous border to the tip. The middle portion of these 

 rectrices in Ph. 7iattereri is onlyslightly tinged with violaceous 

 on the inner web, while they are altogether blacker for a 

 long distance on both webs in Ph. longuemm'ei. 



Besides these differences in the colour of the tail, I observe 

 that in Ph. nattereri the underparts of the body are a paler 

 fulvous, the jugulum only being slightly suffused with rufous. 

 The throat does not show the large black spots so conspicuous 

 in true Ph. longuemarei ; these in Ph. nattereri are either 

 completely wanting or invisible except at the extreme bases 

 when the feathers are raised. The top of the head is a 

 paler sandy rufous-brown. The upper tail-coverts are 

 nearly uniform dark rufous, with no trace of the green spots 

 to be seen there in the other species. The black tip to the 

 under mandible is reduced to a minimum, being much shorter 

 than in Ph. longuemarei. 



I may add that, by the courtesy of Oberamtmann F. Heine, 

 I have been able to examine at St. Burchard, near Halber- 

 stadt, the type specimen of Ph. apheles, Heine, described in 

 Journ. f. Orn. 1884, p. 235, said to have been collected by 

 Warscewicz in Northern Peru. The type is a very bad and 

 imperfect specimen, but appears to me to belong to another 

 distinct species of this group, differing from Ph. nattereri by 

 the pure black and broad subapical band to the outer tail- 

 feathers and in its much shorter wings. In other respects it 

 agrees well with Ph. nattereri both in having no traces of black 

 spots on the throat, as well as in the narrowness of the tail- 

 feathers and the large amount of rufous to the tips of the 

 outer tail-feathers, which characters suffice to distinguish it 

 at a glance from the allied Ph. longuemarei.
