(1467) Trogonurus bolivianus {Grant). 



Trogon bolivianus Grant, Cat. Bds. B. M. XVII, 1890, p. 470, pi. xv, (Cosni- 

 pata, Peru). 



Two males and a female from the Caqueta region should apparently be 

 referred to this species. They agree with an "Ecuador" Specimen and dif- 

 fer from a male from the lower Beni in Bolivia only in the practical absence 

 of the white pectoral zone. Hellmayr (Nov. Zool., XV, 1908, p. 88) sug- 

 gests that bolivianus is a synonym of hehni Gould. Grant, however, lists 

 Gould's type under Trogon variegatus and examination of Gould's figure and 

 description (Mon. Trog. 2nd Ed. 1875, pi. 20) confirms this view of its rela- 

 tionships. In spite of the fact, therefore, that the type of hehni is said to 

 have come from Bolivia and that our specimens from the Lower Beni agree 

 closely with others from Napo and southeastern Colombia, I accept Grant's 

 name for the more western bird. Four males (one each from La Morelia, 

 near Florencia, " Ecuador," and the Lower Beni) differ from nine others from 

 Chapada, Matto Grosso, which I assume to be variegatus, in having the back 

 much greener, less bronzy, the breast bluer, the white pectoral zone less 

 pronounced or absent, the white bars in the tail narrower and black ones 

 correspondingly wider. A female from the lower Beni has an indication of 

 the white pectoral zone, but it is by no means so pronounced as in a Chapada 

 female. The white in the tail of the Beni specimen is practically confined 

 to the outer margins of the three outer feathers, except for a very narrow 

 tip, whereas in the Chapada bird it extends to the inner web and the tip is 

 much broader. A female from La Morelia has no white in the breast and 

 even less in the tail than the Beni bird. Doubtless the latter to some extent 

 approaches variegatus but so far as the present material goes it is unques- 

 tionably referable to bolivianus.
