" Iris, brown, feet blae-grey, bill black, lower mandible of 

 females grej." 



These specimens as well as others from IST.W. Ecuador (San 

 Javier) agree perfectly with typical Panama examples. Skins from 

 Miravelles, Costa Rica, have, as a rvile, the wing a trifle larger, 

 and have the back of a clearer, brighter chestnut, but these 

 variations are so inconstant that it appears to me highly im- 

 probable that the northern form, H. n. capnitis Bangs * can be 

 maintained. This view is shared by Mr. Carriker f, who collected 

 a large series of this species in Costa Rica. 



Birds from different localities measure as follows : — 



Five adult males from Miravelles, Costa Rica : wing 66-67 ; 



tail 34-37 mm. 

 Two adult males from Panama : wing 65, 65 1 ; tail 36, 37 mm. 

 One adult male from W. Colombia : wing 63 ; tail 38 mm. 

 Three .adult males from N.W. Ecuador (S. Javier): wing 



63-65 ; tail 35-37^ mm. 

 Four adult females from Miravelles, Costa Rica : wing 



63-65 ; tail 33-36 mm. 

 Two adult females from W. Colombia : wing 62, 61 ; tail 37, 



34 mm. 

 One adult female from IST.W. Ecuador (S. Javier) : wing 61 ; 



tail 36 mm. 



Both Mr. Bangs and Mr. Carriker give " Pasto, Cauca valley, 

 Colombia " as the type locality, but this is an obvious error. 

 First of all, Lafresnaye does not say where his type came from, 

 and secondly the occurrence of H. ncevioides in the vicinity 

 of Pasto (which lies high up in the mountains at an elevation 

 of nearly 8000 feet) is utterly impossible, the species being- 

 restricted to the humid, tropical lowlands, from sea-level to about 

 2000 feet. Delattre most probably obtained the type at 

 Panama, whence there are two of his skins in the Derby Musexan 

 (see above).
