These examples agree e.xaetly with a large series trom Cnmaiid, Brazil, British 

 Guiana and Bogota coll. In Hie C'tl. Birds Brit. Mus. most of the specimens of 

 this species have been jilaced under M. /liffrice/is, while two others arc registered 

 as a different species : .1/. Irii-olor !' As a matter of fact, however, the former are 

 absolntel)- identical with those from Baliia and Uio Tocantins. The distribution of 

 the two species or subspecies is as follows : 



(a) Mi/iarchiM tuberculifer (Lafr. & D'Orb.) 



Brazil: ]{io, Bahia, Mattogrosso, Para, I'.orba ; /■.'".v/ Bnlirin : (Jnarayos ; 

 Ujjjier Amozonia : Iquitos, N.E. Peru ; Sarayaen, East Ecuador ; Coloinhia : Bogota 

 coll.; Venezuela: Merida ; S. Estelian ; Cumana : Orinoco valley (Quiribana de 

 Caicara, Nericagna) ; Trinidad: Brit, (iniaim : Koraima, etc. 



Obs. Having not seen specimens from Santa Marta and Panama, I cannot say 

 whether they belong to this or to the next form. 



(4) Myiarchus nigriccps Scl. 



Western Ecuador : Pallatanga, Esmeraldas, Chimbo, Bngnac, Nicbli, etc. ; and 



yprfherH Peru: Tambilln, Callucate, Cnlervo, Ilnaiubo, Tamiapampa, 

 C'ajabamba, Malea, etc.

These specimens, as well as some others from Tobago, are practically identical 

 with a series from ('nmana and the Orinoco Biver. They evidently represent 

 typical M. ti/rannulu.^. 



.\r. t. ohcri Lawr., from the Lesser Antilles, differs in its larger and longer bill, 

 decidedly darker njiper parts, and in having the whole inner web of the outer tail- 

 feathers rnfons. .1/. t. brccijjcnnis Hart., from Curacao, etc., on the other hand, is 

 much smaller, especially witli a considerably shorter and weaker bill. 



T4. Tyrannus melaucholicus satrapa (Cab. ^V, Heine).

Many s[.ecimens from Caparo, Aiiril, agreeing in size and colour with a series 

 from Tobago, Panama, Costa Bica and British Guiana. The nortliern form differs 

 from typical T. m. melancliolims only by its somewhat larger size. On the other 

 hand, T. m. couchi Baird is a strongly marked race, easily known from those of 

 South America by its largrr size, paler, more whitish throat, much less greenish 

 suffusion on the foreneck and ninch paler yellow belly.
