The male, No. 20i7, and female, No. 2818, agree in 

 colour of plumage very well with the type in the British 

 Museum, but Nos. 3080 and 3087 differ, especially the 

 male, in being perceptibly paler both on the upper and 

 under surface. They are also slightly larger in wing- 

 measurements [c^ 140 mm., ? 145, as against cJ 138, 

 ? 142] . I do not attach any importance to these measure- 

 ments, however, as the wing-measurement of the type is 

 148 mm. and it is a much darker bird. The difference of 

 altitude, moreover, may account for the pale coloration 

 of the El Cabrada specimens, which ap[)roach N. coquimbica 

 in the colour of the back and the pale under surface. 



Nothoprocta pentlandii simonsi. 



Nothoprocta pentlandii simonsi Chubb, Bull. Brit. Orn. 

 Club, xxxviii. 29 Dec. 1917, p. 30. 



This subspecies is somewhat intermediate between N.cur- 

 virustris peruana and N. pentlandii pentlaudu. It approaches 

 the head and back of the former and the grey fore-neck, 

 with buify-white central spots, and secondary quills of the 

 latter. 



The type, No. 1414 ? , which is in the British Museum, 

 was collected at San Pablo, Cajamarca, Peru, at an altitude 

 of 1500 metres, on 5 November, 1899.
