444 Bangs and Noble, Birds of Peru. [q£ 



color than any from farther south, and for this large dark northern form, 

 we propose the name — 



Accipiter bicolor fidens subsp. nov. 



Type from Buena Vista, Vera Cruz, Mexico, fully adult 9 , No. 2289 

 Bangs Coll. (in Museum of Comparative Zoology). Collected June 14. 

 1901, by A. E. Colburn and P. W. Shufeldt. 



Characters. Larger and darker than A. b. bicolor (Vieill.), upper parts 

 blackish slate, under parts slate gray. Type 9 ad., wing, 260; tail, 209, 

 tarsus, 67; culmen from cere, 20.5. Topotype, No. 2290, 9 immature, 

 wing, 255; tail, 212; tarsus, 68; culmen from cere, 18. 



Only one of the five specimens in the series contained food in its crop. 

 This consisted of five or six large cockroaches. 



Heterospizias meridionalis (Lath.). One young (cf?) with the under 

 tail coverts still in down, Perico, September 16. 



Rupornis magnirostris occidua Bangs. Ten specimens, one imma- 

 ture 9 , and adults of both sexes. Bellavista and Perico, September. 



These skins are very uniform in character and agree exactly with the 

 type. Compared with a fine series of true R. magnirostris from Para- 

 maribo, Surinam, kindly lent us by T. E. Penard, they are very different. 



By far the commonest hawk met with throughout the Valley of the 

 Maranon and Chenchipe was this species, but the bird was not seen to the 

 west of the Andean range. 



The crops and stomachs of the ten specimens collected contained the 

 following variety of food : 



4. Burrowing Snakes (Glauconia). 



1. Burrowing Lizard (Bachia). 



2. Mice. 



1. Chilopod. 

 1. Grasshopper. 



Herpetotheres cachinnans maestus subsp. nov. 



Two females, one immature, one adult Bellavista and Perico, September. 



Type from Bellavista, Peru, adult 9 No. 80152 M. C. Z. Collected 

 September 19, 1916, by G. K. Noble. 



Characters. Size small, and under wing coverts heavily spotted as in 

 H. cachinnans fulvescens Chapman of western Colombia, but with the 

 under parts very much whiter — buffy white. Similar also to H. c. cachin- 

 nans (Linn.) of Guiana, but smaller; the under wing coverts more heavily 

 spotted, and the underparts paler — whiter.
