coy PHELPS, Birds observed in Venezuela. 363 
o 
A sixth form, Playtrhynchus mystaceus insularis, 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= Cumand4; CC = Cumanacoa; S = San Antonio ; 
G = Guanaguana; Ca = Caripe.

1Since 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.
