6 ARKIV FÖR ZOOLOGI. BAND 14. N:0 25. 



With regard to the zonal distribution of the species in 

 the above list there is a certain discordance between Chapman's 

 statements and our own view as to the occurrence of some 

 few species. The author quoted considers for instance Opistho- 

 prora euryptera, Andigena hypoglauca, Dendrocincla tyrannina 

 and Sericossypha albicristata as members of the temperate 

 fauna, while we have our specimens from a lower altitude, 

 thus from the subtropical zone. The first of the species enu- 

 merated we have obtained from an altitude of something be- 

 tween seven and eight thousand feet, but the others in several 

 specimens as low as between six and seven thousand feet, so 

 that in the latter cases most certainly the birds in question 

 must be at home as well in the subtropical as in the temperate 

 zone. 



On the other hand there are also some few species which 

 Chapman records as tropical, but which we have from the 

 subtropical belt. One of these I by eter americanus has as a 

 bird of prey without doubt a wide range. Two others viz. 

 Ostinops angustifrons and Cacicus cela are in the present col- 

 lection represented by specimens from an altitude of 6000 f . and 

 may thus Ii ve as well in the subtropical as in the tropical zone.
