H[eteyoccrctis] angosturae Berlepsch & Leverkiihn Ornis. VI.: 1890: 
19 (Orinoco). 
Common about Perico and at IMaipures. not noted elsewhere. 
Laxkichr-a hvpopvrrha (\'ieillot). 
Ampdis hypopyrrha Meillot, Nouv. Diet. VIII. 1817. p. 164. 
Laniocera hypopyrrha Berlepsch & Hartert, p. 57. 
This species was noted only once, a male having been taken at 
N'ericagua April 5, 1899. Berlepsch and Hartert also record specimens 
from Suapnre. La Pricion and La L^nion on the Caura River. 
COTINGIDAE— COTINGAS. TITYRAS. ATTILAS, BECARDS, 
ETC. 
Fourteen species are included in the present paper. Only eleven 
of that number however were observed or collected by the writer on 
the Orinoco proper, the other three species were included in the 
Berlepsch and Hartert paper and came from points on the Caura River, 
but as pointed out in my remarks under Tyrannidae, there are a number 
of species included under that heading having structural characters that 
indicate their nearer relationship to the Cotingidae.
