o62 Hans Graf von Berlepsch : 



The violaceous colour of the throat and the middle belly is 

 rather darker, nearly black ; the blue of the upper parts is 

 also darker, and the top of the head is shaded with darker 

 violaceous. The blue band on the upper breast is broader. 

 There is a bright blue spot on the upper chin wanting in the 

 other species. The wings are longer, and the bill much 

 longer and broader. The third primary is rather narrower. 



In all other points, especially in the length of the upper 

 and under tail-coverts, it agrees perfectly with G. ridgwa/yi. 



The female is quite differently coloured from that of 

 G. amabiUs,i)iit agrees very well with the female of G. cay ana. 



In the Rothschild Museum at Tring I found a pair of this 

 species, collected by M. André at El Pailon, near Buena- 

 ventura-, and there is a male from unknown locality in the 

 British Museum.

 [G. Garlepp leg. No. 763.] 



Mr. Gustav Garlepp sent me five specimens of this new 

 form, all collected in different parts of Eastern Bolivia, viz., 

 at Samaipata, Valle Grande, and Olgin. 



They differ invariablyr^m specimens from Brazil (Bahia 

 skins) in having the wing feathers externally bordered by 

 olive-brown instead of cinnamon-rufous, only the borders of 

 the primaries showing a slight rufescent shade, while those 

 of the secondaries are concolorous with the back. The back 

 has a darker shade, being more olivaceous, less rufescent. 

 The cinnamon-rufous of the tail is somewhat darker, and 

 the inner webs of the middle tail-feathers are more generally 

 fuscous, while they are only bordered with blackish on the
