Remarks.— The occurrence of a form of Curucujus at Barbacoas extends 
the known range of this species southward from Noanama in western 
Colombia. From Noanama Hellmayr (J. c.) records an adult male which 
evidently belongs to the form I have here described, since he states that 
‘compared with others from Central America, this bird is smaller, and has 
the middle pair of rectrices washed with dull bluish instead of bronze green.” 
A female from Bagado, near Quibdo, further confirms the belief that C. m. 
australis is the form of this region. It agrees with a female from Barbacoas. 
in color but has the tail considerably longer. ‘The tail in the Barbacoas 
specimen, however, is so much shorter than the wing that it is difficult to 
believe the specimen is of normal size. 
Unfortunately I have only one female from Barbacoas and this with 
the type and the Bagado female are all the specimens I have seen of the 
proposed new form. Of C. m. massena we have an excellent series taken 
from Mexico to Panama.

Andigena nigrirostris occidentalis subsp. nov. 
Char. subsp.— Similar to A. n. spilorhynchus (Gould) but with the red area at the 
base of the bill larger on the maxilla and crossing the base of the mandible. 
Type.— No. 107922, Am. Mus. Nat. Hist., ad., San Antonio (alt. 6600 ft.), 
Western Andes, above Cali, Colombia, Jan. 8, 1911; W. B. Richardson. 
Range.— Subtropical zone of the Western Andes of Colombia. 
Remarks.— In this race, which is based on twelve specimens, chiefly 
from the type-locality, we have the extreme departure from the nagrirostris 
type of bill coloration, the first stage of which 1s marked by A. n. spilorhyn- 
chus. A specimen of the last-named form from Ecuador, has much less 
red at the base of the maxilla and none at all on the mandible. In describing
