1915.] Chapman, New South American Birds. 3ol9 
Remarks.— The characters here given are shown by six males from 
various localities in Chile on comparison with fourteen males from Chapada, 
Pernambuco, and San Paulo, Brazil. In only one of the Brazilian birds, 
an immature specimen from Chapada, Matto Grosso, is the tail apprecia- 
bly tipped with rufous; nor do I find this character shown by other South 
American forms, except in C. s. fernandensis which is presumably an off- 
shoot of connamomina. Five of the Chilean birds have only the subterminal 
bar on the outer rectrix. The sixth specimen has three bars on this feather. 
On the other hand, eleven of thirteen Brazilian birds have the outer rectrix 
with two or more bars, while only two have but the subterminal bar. Pos- 
sibly this marking may here have a racial significance. It should be 
observed, however, that of twelve specimens of fernandensis, obviously an 
island representative of cinnamomina, five have the outer rectrix with only 
a subterminal band while seven have two or more bands on this feather. 
Specumens examined.— Chile: Chile, 2 oo’, 1 2; Corral, 19; San- 
tiago, | @ 3° Valdivia, Po"; Cauun, 1, 20-9 Anedd, 23070". 
Cerchneis sparverius fernandensis subsp. nov. 
Char. subsp.— Similar to C. s. cinnamomina but more deeply colored and more 
heavily marked; ventral region and lower tail coverts clear buff; male with the 
upperparts darker, the black bars less sharply contrasted with the rufous inter- 
spaces, the underparts more heavily washed and with the spots larger and more 
numerous, those on the flanks being, in some specimens, broad black bars; female 
darker above, the black bars less sharply defined, the underparts (except throat) 
much deeper, in some specimens dull rufous obscurely streaked and spotted with 
blackish. 
Type.— No. 2335, Brewster-Sanford Coll. # ad. Juan Fernandez (Masatierra) 
Island, Jan. 14, 1914; R. H. Beck. 
Range.— Island of Juan Fernandez, off Chile. 
Remarks.— The Brewster-Sanford collection, which is on deposit in the 
American Museum, contains an excellent series of this strongly marked form 
collected by R. H. Beck. For comparison with this large series I have six 
males and five females of cinnamomina from Chile. The rufous at the tip 
of the rectrices, which is the chief distinguishing feature of connamomina, is 
present in a greater or less degree in fernandensis. As regards the markings 
of the outer rectrix, five males of fernandensis have only a subterminal bar 
on this feather while seven have two or more bars. 
In the rich coloration, especially of the ventral region, and heavy mark- 
ings of the underparts, the male of fernandensis is approached only by 
another insular form, C. s. antillarum. The females of these two races,
