°jg" I Phelps, Birds observed in Venezuela. ^6'^ 



A sixth form, Playtrhynchus mystaceiis insiilaris, was found by 

 Lieut. Robinson at Laguayra, so there are now but six ^ forms 

 left which as yet have not been found on the continent. I doubt 

 if these will long remain peculiar to Trinidad, and I believe that 

 as the birds of the nearby mainland become better known, 

 those few remaining species will gradually be eliminated. 



As the distinctness of the Trinidad avifauna is reduced by the 

 occurrence of these forms on the mainland, so is the distinctness of 

 the Eastern District of Dr. Ernst increased. This district was 

 first recognized by the occurrence of many birds from the 

 Guianas and Brazil which did not seem to occur further west- 

 ward in Venezuela. If further study in other parts of Venezuela 

 shows that the above mentioned subspecies are restricted to the 

 northeastern part of the country, and to Trinidad, then there is. 

 added the evidence that, in addition to these species from the 

 southeast, several forms attain subspecific rank in this district. 



I give here a list of the birds observed ; all those not marked 

 with a * are represented in my collection by skins. Letters 

 following the names indicate the localities where the species was 

 found ; thus C = Cumana ; CC = Cumanacoa ; S = San Antonio • 

 G =1 Guanaguana ; Ca = Caripe.

' Since the paper above quoted was written Mr. Chapman has described 

 Synallaxis carri from Trinidad (Bull. Am. Mus. Nat. Hist., 1895, VII, p.32). 

 This species has not been found on the mainland.
