and the abdomen, under tail-coverts, and under wing-coverts 

 are also proportionately darker than that of the typical bird. 

 There are six specimens of this form — one male, three 

 females, and two unsexed. 



The wing-measurements are: — o 67 mm., ? ? ? 60-61, 

 unsexed 61, 65. 



Hab. Tobago. 



The type, which is in the British Museum,, was collected 

 by J. Kirk : Jardine Collection. 



Hellmayr (Nov. Zool. xiii. p. 22), when naming M. o.pal- 

 Udiventris from Cumana, mentions that one Tobago bird 

 agrees with the Cumana skins in differing from thirty skins 

 from more southern localities in the decidedly paler orange 

 colour of the belly, much less greyish-green suffusion of the 

 throat, and duller olive-green upper parts. The material in 

 the British Museum, however, does not support this statement, 

 as the six examples from Tobago in tiie National Collection, 

 compared with two individuals from Bahia and two from Rio 

 de Janeiro, are decidedly darker in every respect than in 

 the birds from the typical locality.

In British Guiana there are two forms — a smaller and 

 more brightly coloured bird on Mount Roraima and the 

 Mernme Mountains and a larger and darker one in the low- 

 lying country. The latter bird is darker on the upper parts 

 than any of the other forms. In this respect it is more 

 closely allied to P. o. tobagoensis } but differs in being more 

 brightly coloured on the abdomen, under tail-coverts, and 

 under wing-coverts. 



Wing 65 mm. 



Hab. British, Dutch, and French Guianas. 



The type, which is in the McConnell Collection, was 

 collected on the Kamakabra River, 1911.
