wol'ks on Sonth American Ornithology Burmeister seems to have indicated this species under
the name T. crotopezus, having been no doubt misled by Lichtenstein’s reference to Azara in his
original description o f that speeies. ■ But, as we shall presently shew, the true T. crotopezus, so
well described by Prince Max., is a different species, dislinguishahle from the present bird by the
rich reddish brown o f the plumage above, the more densely striated throat, and other differences
which we shall hereafter point out.
In 1857, Sclater described a Tbmsh from Bogota, under the name Turdus ignohUs, from
specimens in his own eolleetion and in that o f the Academy o f Natural Sciences o f Philadelphia.
After carefully comparing the New Granadian bird with a series o f skins from other Ioc.alities,
we are now o f opinion that there are scarcely sufficient grounds for separating it from the present
species. Tho only points o f difference are the lighter coloured loros, and somewhat darker
breast in some specimens. But in more recently obtained examples, these distinctions do not
seem to be constant.
How d’Orbigny came to make the mistake o f regttrdmg this Thrush as the female of
T. rufiventris, we cannot explain ; suffice it to say that, as Burmeister observes, they do not
even inhabit the same sort o f coimtry ; T. mfiventris being a forest-lovmg species, whereas the
present bird seems to be peculiar to the Campos, and more open districts.
As will be seen by the list o f localities above given, as well as from what has been
already stated, the range of Azava’s Thrush in South America is very extensive, stretching from
New Granada and Ecuador in the north to the Pampas o f Buenos Ayres in the south, but from
what has been recorded o f its habits, it would appear to shun the densely wooded districts and
to oocur only in the savannas. In the vicinily o f Lagoa Santa, where Bunneister tells us that
it is b y no moans scarce, its terrestrial habits are stated to cause it to be subject to the attacks
of the “ jigger” ( Pulex penetrans)—s. well-known pest o f the American tropics.
Onr figure o f tliis species is taken fi-om a skin in Selater’s collection, whioh from the mode
o f its preparation appears to be from Cayenne.
