Five specimens of this form were collected at the type-locality. The 

 genus had not before been recorded from Colombia and its restriction to 

 the Central Andes indicates the close connection which exists between that 

 chain and the main Andean system of Ecuador. Upucerthia excelsior Co- 

 lumbiana furnishes a similar case.

(2746) Platytriccus flavigularis (ScL). 



Plaiyrhynchus jiavigularis Scl., P. Z. S., 1861, p. 382 (Bogotd). 



Five specimens from the Subtropical Zone of the Central Andes agree 

 with descriptions of this species of which I have seen no authentic specimens.

(2751) Platytriccus albogularis (Scl). 



Plaiyrhynchus albogularis Scl., P. Z. S., 1860, p. 68 (Pallatanga, Ecuador);

Platytriccus mystacev^ albogularis Hbllm., P. Z. S., 1911, p. 1125 (Pueblo Rico). 



Our five specimens are from the Tropical and Subtropical Zones. They 

 are somewhat less richly colored below and less brown above than a series 

 from western Ecuador.

(2752) Placostomus coronatus {Scl). 



Plaiyrhynchus coronatus Scl., P. Z. S., 1858, p. 71 (Rio Napo, e. Ecuador). 



Two specimens from La Morelia are doubtless typical of this species 

 which appears not to have been before recorded from Colombia.

 Cyclorhynchus cequinoctialis Scl., P. Z. S., 1858, p. 70 (Rio Napo, Ecuador). 



Apparently restricted to the Tropical Zone at the eastern base of the 

 Eastern Andes. I have seen no Napo specimens but our four birds are 

 doubtless fairly typical. 



La Morelia, 3; Florencia, 1.
