THE BIRDS OF THE JUAN FERNANDEZ ISLANDS 5 
DAUTHENAY. Smaller wing-coverts a little more brownish, greater coverts 
blackish, broadly margined with a dark shade of raw umber; bend of the wing 
white. Primary coverts black, the outermosts broadly edged with isabelline, or 
brownish white. Primaries blackish brown with obsolete paler edgings, the 
fourth and fifth with a broad band of pale cinnamon (OBERTHUR and DAU- 
THENAY 323,1) across the inner web; on the sixth and following, except the 
innermost secondaries, this band extends over the outer web as well, at the 
same time assuming a brighter, more saturated cinnamon colour (323, 2 or 3). 
Distally of this cinnamon band there is a broad band of pure black, which 
again distally is contrasted by the edges, here brown, of the corresponding quills. 
Inside the cinnamon band the four innermost secondaries are black, edged with 
sepia like the back. On the lower side of the wing the cinnamon band appears 
white. Under wing-coverts white along the edge of the wing, otherwise mixed 
with ashy grey; axillaries white. A superciliary stripe of white or creamy 
white extends from the base of the bill to the nape; it is broader and more 
conspicuous behind the eye. Ear-coverts like crown, but partly with whitish 
shaft-stripes. Throat and fore-neck white, but the feathers tipped with grey, 
so that a mottled or scaly appearance is produced. Upper breast light grey, 
almost paler than »mouse-colour» (O. and D. 360,1) with a creamy white spot 
on each feather. Anteriorly these spots are more roundish, but change into 
light shaft-stripes further down the breast. In some specimens this striped 
pattern extends further down on the lower breast as well, in others the centre 
of the lower breast is whitish like the centre of the belly in all. Flanks brownish 
grey or brownish ash. Crissum about similar, but all feathers edged and tipped 
with whitish and often with narrow light shaft-stripes. Tail black, the two outer 
tail-feathers tipped with cinnamon, which colour on the outermost extends half 
the length of the quill.

The specimen from Masatierra is similar to the others. 
If this description of the Czxzclodes from Juan Fernandez is compared with 
ScoTrT’s original diagnose of C. oustaletz and the additional notes of HELLMAYR, 
a certain discrepancy is to be seen. Firstly, SCOTT says about C. oustaleti 
»pileo dorso concolori», which does not hold good for the present series of 
birds from Juan Fernandez. The same is also the case with HELLMAYR’s sta- 
tement: »uniform rufousbrown crissum», or the corresponding one of the author 
quoted and of MENEGAUX (Bull. Soc. d’hist. nat. d’Autun. Vol. 19, p. 62): 
»les souscaudales d’un brun roussatre uniforme». ScoTt’s description of the 
lower side of C. oustalett, viz. »subtus chocolatino-brunneus, nec grisescens et 
minus distincte striatus», is also not quite suitable for the Juan Fernandez bird. 
As the latter, however, nearly agrees with C. oustaleti with regard to size, 
white axillaries & ca., I think it most convenient to regard the insular form
