Type of T. e. baeri Hellm. t? ad., Goyaz, April 1906. No. 2073. Coll. 

 G. A. Baer. — Tring Museum. 



The males of this well-marked form differ from those of T. e. eripitile, which 

 they resemble in general coloration, and especially in having the forehead glittering 

 golden green, in much smaller size, and in the colour of the under tail-coverts. 

 These are either pure white, or some of the shortest feathers only show very small 

 discs of bluish black or dark bronze green. The specimens from Chiquitos and 

 Mattogrosso fully agree with the Goyaz series. 



The females of T. e. baeri are considerably smaller than those of the typical 

 race, of which I have seen several examples from Minas Geraes. There appear 

 to be no colour differences. A female from Mojos, Eastern Bolivia, is practically 

 identical with that sent by Mons. Baer. 



T. e. baeri is a very interesting form, being intermediate between T. e. eripkile 

 and T. balzani Sim. With the former it shares the glittering frontal patch, 

 completely absent in T. balzani ; with the latter the white under tail-coverts and 

 the small size. In typical T. e. eriphile the males have the under tail-coverts 

 always uniform bluish black or dark lironze-green, sometimes with narrow 

 whitish fringes. 



The characters and geographic distribution of the three forms may be 

 summarised as follows : 



(a) T. eripkile eriphile (Less.). 



c?. Larger : wing 59 — 62 ; tail 39 — 44 mm. Forehead as far as the anterior 

 angle of the eye glittering green, sharply defined against the dark bronze-green 

 of the vertex. Under tail-coverts bluish black or dark bronze-green, either 

 uniform or narrowly fringed with whitish. 



?. Larger : wing 55 — 57 ; tail 33^—35^ mm.
