the Marafion, at elevations from 1200 to 1500 metr. It seems to be rather common 

 i:i the valley of Huayabamba, where Messrs. G. Garlepp and 0. T. Baron procured 



a large number of specimens. Mons. Baer met with it near Naevo Loreto. I 

 compared our series from these localities with Gould's types iu the British 

 Museum, and found them perfectly alike. I doubt, however, whether the original 

 examples were really obtained " in the neighbourhood of the River Ucayali." * The 



8 of T. tschudii is easily recognisable by the green colour of the throat being 

 separated from the purple-blue abdomen by a distinct greenish-blue area, which 

 is bordered laterally by a velvety black line. Messrs. Berlepscb and Hartert t 

 recorded this species from the Upper Orinoco, aud the specimens from there are 

 certainly very much like the Peruvian ones, especially on the underparts. Mosl 

 of them are, however, immature, and the only adult 8, which is much damaged by 

 the shot, seems to have a violet baud across the interscapular region. I feel sure 

 that if a scries of adult 8 8 could be compared, the distinctness of the Orinoco form 

 would become apparent. 



(3) T, jelskii Tacz. inhabits the Andes of Central and South-eastern Peru, 

 aud of North Bolivia. The Tring Museum possesses this form from La Gloria 

 (Chanchamayo), elev. 1100 metr.; Carabaya, 1000 metr.; and a series from San 

 Angnstin, Eastern Bolivia, 1200 metr. Here belong also all the Bolivian specimens 

 iu the British Museum, recorded by Salving s.n. T. tschudii, and the examples 

 obtained by D'Orbigny near Santa Cruz § and preserved in the Paris Museum. 

 The 8 8 of T. jelskii differ from T. tschudii by the green throat being immediately 

 followed by the royal purple colour of the breast and abdomen. 



(4) T. balzard Sim. replaces the foregoing species in the lowlands of Eastern 

 Bolivia. The Tring Museum received a good series from Salinas, on the banks of 

 the Bio Beni. The 88 ad. of T. balzard are at once known by their pure white 

 under tail-coverts, which occasionally show a few very small blackish discs near 

 the base.
