Mr. O. Salvin^s Synopsis 
Like S. picta, it is a restless species, constantly searching 
for its food amongst the leaves and branches of the oak trees 
it frequents. It seems to be a resident species, as we found 
it at nearly every season of the year—^in January, July, 
September, and November.

This is a close ally of S. verticalis, which it replaces in the 
highlands of Veragua and Costa Bica. It differs chiefly in 
having the underparts orange rather than lemon-yellow. 
There is also a diflPerence in the amount of white in the outer 
rectrices between the two species, these feathers in S. veriicalis 
having much more white than those of its ally; the dark mark¬ 
ings of the head of S. aurantiaca seem to be blacker than in the 
other species. At one time I somewhat doubted there being 
two species of this form; but having since seen a large 
number of examples of both, all showing the constant diffe¬ 
rences pointed out above, I now think that their separation 
is justifiable. This, indeed, was the view taken by Mr. Sclater 
and myself when compiling our Nomenclator.’ 
As regards the bird called S. flammea by Dr. Cabanis, there 
can be no doubt that it really belongs here. This was appa¬ 
rent when I examined the specimen in the Berlin Museum. 
It would appear that S. aurantiaca is a common species in 
the highlands of Costa Bica, as specimens occur in almost all 
of the collections made in that country, it having been ob-
