much to extend our knowledge of the bird-fauna of that part of the isthmus, showed us 
that the range of this species extends to the Cordillera del Chucu, on the confines of 
the province of Chiriqui. 
Of the habits of Calliste dowi as yet we know nothing. 
The nearest ally of this species appears to be C. nigriviridis, though the presence of 
an occipital spot suggests an affinity to C. ruficervix of Colombia and Ecuador, and 
to C. fulvicervix of Bolivia, and with all these birds it must no doubt be grouped. 
C. dowi, however, has characters of its own, rendering it easily recognizable.

The true status of this plainly coloured species was questioned for some time; and it 
was even suggested that it might be merely the young of Calliste larvata, or the female 
of that bird‘. Mr. Sclater, hesitating as to its true position, placed it at the end of his 
Monograph of the genus®. Its describer, Gould, whose judgment in such matters was 
seldom at fault, always stoutly maintained the plain colours of the bird were its normal 
adult dress, and that its distinctness from all others was complete. ‘This view has now 
been proved to be perfectly correct. 
Of C. larvata we have specimens of both sexes carefully dissected, and we find that 
there is hardly any appreciable difference between them. Of the young, too, of 
C. larvata we have several examples in moult from their first plumage; and these, too, 
differ so much from C. inornata that no question of the identity of the two birds can 
be maintained fora moment. This, too, is Mr. Lawrence’s conclusion °. 
Gould’s type of C. inornata was a skin from one of the ordinary trade collections from 
Bogota, and in such collections specimens may occasionally, but not very commonly, be 
found. It is probably in the valley of the Magdalena that these specimens are obtained, 
as we know nothing of the bird from the eastern side of the Andes, and, on the other 
hand, Salmon found it at Nechi in the State of Antioquia’. Passing northwards, it 
was met with during Lieut. Michler’s expedition’; and at Panama it seems to be more 
numerous than elsewhere, so far as our present knowledge goes. It has also been 
included in Arcé’s collections, made probably in the vicinity of Calobre; but on this 
point we have no exact information.
