crown of other races; the nape is not materially darker than the 

 forehead. Males do not exhibit the orange on the rump and abdomen, 

 which is found in most, but not all, specimens of aurantiicinctus. 

 Females of insperatus can be distinguished from our females of 

 aurantiicinctus only by their much paler, uniformly colored crown. 

 Specimens examined. — Bolivia: Todos Santos, Province of Cocha- 

 bamba, 4 males, including the type, 1 female; Mission San Antonio, 

 Province of Cochabamba, 3 females; Rio San Antonio, 1 female; 

 "Bolivia," 1 female. Peru: Rio Cosireni, 1 female; Astillero, Rio 

 Tambopata, 1 male. 



CAPITO AURATUS BOLIVIANUS RIdgway. 



The type of this race, a male, is now before me. It was found by 

 Dr. Thomas Barbour attached to an Indian necklace in a museum 

 in La Paz, Bolivia, and was supposed to have come from the Rio 

 Beni. It is the most richly colored bird in our series, but can be 

 nearly matched by a male from the Cunucunuma River. The under- 

 parts of the type are deeper, and there is a trace of an orange abdom- 

 inal band; the crown is antique brown with an old gold tint, slightly 

 darker than that of the Cunucunuma bird. The yellow streaks on the 

 back agree with those of the Cunucunuma bird, but there is no orange 

 on the rump. 



Our specimens seem to prove that insperatus ranges from southern 

 Peru to Bolivia, east of the Beni and indicate that the locality at- 

 tributed to the type of holivianus is incorrect. Indeed, without a 

 more definite data in regard to the Indian necklace to which as an 

 ornament it was attached, one can not say where this type came 

 from, but regardless of locality it is clearly more closely related to 

 the Orinoco bird than to any other known form of this interesting 

 group. 



(1517) CAPITO VERSICOLOR (P. L. S. MUIIer). 



Bucco versicolor P. L. S. Muller, Syst. Nat. Suppl., 1776, p. 88 ("Maynas"). 

 Capita versicolor Berlepsch and Stolzmann, Ornis, 1906, p. 98 (Idina). 



Common in the Subtropical Zone at Idma. One male has the 

 malar stripe largely yellow, in two others it is tinged with yellow, 

 thus showing the approach to C. glaucogularis which was commented 

 on at length by Berlepsch and Stolzmann in recording a specimen 

 from Idma.^'' The malar stripe averages broader than in specimens 

 from Bolivia. 



Idma, 6 males, 3 females.
