than a Cayenne specimen, two of them being but slightly darker than a 

 specimen of insularis from Curasao, loaned me by Mr. Todd. The latter, 

 however, has black (and that as a small broken band) on only the outer 

 pair of tail-feathers. A male from La Playa agrees with the Villavicencio 

 males in general color, but has a black bar on only the outer pair of tail- 

 feathers. Possibly it should be referred to insularis.

Char, subsp. — Wings and tail longer, the bill larger than in S. c. cayennensis, 

 the female much darker throughout, the crown largely black, the central feathers 

 but narrowly margined with rusty or ochraceous-tawny and grayish; the grayish 

 nuchal area almost wanting, the rusty nuchal collar slightly deeper in color; in 

 the back black predominates, the grayish is reduced to a minimum the feathers being 

 minutely marked with broken rusty; scapulars black widely margined externally 

 with buff or ochraceous as in cayennensis, black tail-bars wider and more pronounced, 

 breast and flanks more heavily barred. 



Our four specimens of this form were all taken at San Antonio in the 

 Western Andes in January and February, 1911. 



(955) Thermochalcis ruficervix {Scl). 



Stenopsis ruficervix Scl., P. Z. S., 1866, p. 140, pi. xiv (Int. Colombia); Sol. & 

 Salv., p. Z. S., 1879, p. 531 (Envigado; Retiro; Sta. Elena). 



Inhabits the Temperate Zone. In view of the fact that in Colombia, as 

 well as in Venezuela and Ecuador, most of our specimens of this bird were 

 taken from above 10,000 feet, I am inclined to regard an immature female 

 collected by Richardson at Tumaco, on the coast of southwestern Colombia, 

 as an accidental visitant at that point. This specimen, it should be added, 

 is considerably paler than any of our other twenty examples of this species.
