agrees with that of fammulata, but the crown is more chestnut; the ‘ throat- 
patch’ is confined largely to the chin, not reaching behind the gape, and is 
bright hazel or Sanford’s-brown, sharply defined posteriorly; the remainder 
of the underparts are white, the feathers, quite to the crissum, being mar- 
gined with black with usually a faint inner ochraceous margin. T his mar- 
gin is less even than in flammulata and quindiana and on most of the feathers 
of the abdominal region appears as paired, subterminal lateral spots which 
indent the median white area but do not reach to the shaft of the feather. 
I observe that Brabourne & Chubb (Bds. S. Am., p. 236) use Sclater’s 
name muiltostriata for the Ecuadorian as well as Colombian bird, presumably 
acting on the assumption that Szttasomus flammulata Less. (Tr. d’Orn., 
1831, p. 315) is, as Sclater thought “ very doubtful” (Cat. B. M., XV, p. 61), 
Siptornis striaticollis (Lafr.). Lesson’s description alone does not seem to. 
warrant this belief, but if it should prove to be correct, the Ecuadorian bird 
here referred to as Stptornis fammulata flammulata (Jard.), will require a 
new name. 
The Choachi specimen is not sexed but its smaller size suggests that it is 
a female, and I have therefore compared it in size with females of the other 
two races.

clearer on the sides of the head; wings externally of the same color as the back, tail 
black; breast somewhat deeper than in nigricauda, the rest of the underparts darker 
brown, less olivaceous, the sides and particularly flanks much darker, nearly the color 
of the back.

Antioquia, Col., Feb. 16, 1915; Miller and Boyle.
