Two specimens oC 7i'. p. jinliorephalus Taez. from Xeberos and the upper 

 Uca^ali are mncli lirigliter yellow nnderneath and the throat is not mixed with 

 whitish. Tiio differences in size mentioned by me I. c. do not appear to be constant. 



I examined one of Wallace's specimens, previonsly determined as R. milphii- 

 irscciis by Sclatcr and Salvin, and tlie S ad. collected by Layardjf and fonnd both 

 to belong to B. p. schiteri.

The series agrees witli s]ici:inicns from British Gniana iiud the Canra TJiver, 

 Venez., excejit that the foreneck is slightly more snffnsed with oclireons. This 

 colonr, however, is much dnller and jialer than in .1/. /j. mastacaUs (Wied) 

 from Babia.

This bird evidently belongs to the typical fm-ni, and differs from a series of 

 the {!anra Hiver only in having the back more fidvons brown, less mixed wilh olive 

 greyish. Topotyi}ical (inianan sjiecimens are not available for comjiaristin. 



The distingnisliiiig characters of the western form, .lA. r. fuh-ii/ii/nri.^ 

 Salv. & Godm., have been jjointed ont by Berlepsch iV- llartert, Aor. Zoo/, ix. (1902) 

 p. 50.

30. Pipra nibrocapilla subsp. 



3 S ad. 2 c? jnv. and 1 ? ad. from Praia: 24, 31. x., 12, 20, 29. xi., 

 12. xii. 05. Nos. 17, 46, 100, 216, 236, 323. Iris marked as "whitish" or 

 " pale yellow." 



The (?c? ad. sent by Mr. Hoffmanns, as well as two others collected by 

 Prof. Steere near Pani, differ from a large series of true /'. ;•. rubrocKpilla 

 (more than twenty specimens) by the mnch lighter, more orange-red colonr of the 

 forehead and crown, which, in the typical form, are of the same dark crimson-red 

 as the occipnt. The difference between the two forms is about the same as that 

 existing between P. m. mentnlis Sel. and P. m. if//ii/?ra Bangs. 



In my pajjcr on the genus Pipra t I alluded to the pale forehead, in two 

 specimens from Pani ; having now received three more skins which exhibit the 

 same peculiarity, I feel quite confident as to the constancy of this character. 



This form will shortly be described by a fellow-student of ornithology.
