OBSERVATIONS ON THE GENUS SCYTALOPUS.

A second example, employed for our description in 1840, differs 
from this, by the feathers of the wing and of the tail being irre- 
gularly streaked with black. We think it is a female, or a male 
not yet adult. 
A third example differs again, by its gray tail, and by the under 
feathers of the tail, not being rufous, but a mixture of brown and 
pray.

*‘M. corpore griseo supra; cinereo infra; abdomine lateribusque

“Corpore brunneo supra, et plumis rufo circumdatis; collo 
antico griseo albente, rufo tenuiter striato 9. Habitat, Chiloé.” 
(Less. Rey. Zool. 1842, p. 135.) 
After this description of Mr. Lesson, this species seems to have 
some relation with our J. griseicollis, but Lesson does not say that 
his Meg. nanus has the rump rufous; besides, his came from Chiloé, 
and ours from Bogota, certainly.

“M. supra totus brunneo rufus, plumis uropygialibus vividé rufis ; 
plumis totis capitis, colli, dorsi, aleque tectricibus et remigibus 
tertiaris vitta nigra squameformi marginatis ; caude tectricibus equé 
nigro vittatis ; gutture, collo antico et abdomine medio pallidé rufes- 
centibus, pectore et hypochondriis nigro-fusco irregulariter striatis ; 
rostrum pallidé corneum ; pedibus pallidis. Long. toto, 38 ; ale, 2; 
caude, 13.” 
This bird, whose plumage is all rufous, variegated and streaked 
with black, is probably a young one; it is remarkable by the sleu- 
derness and shortness of its bill and of its tail.
