VIII. — FURTHER REMARKS ON THE GALBULIDJi. 
Plate XC. 
Sir William Jaiidine writes me, that lie has an example of 
Galbula melanogcnia , described p. G1 of the present year’s “ Con- 
tributions,” and of which a figure is herewith given from V eragua, 
whence it was sent with other skins by Mr. Gould’s collectors. 
Central America is therefore without doubt its true habitat , many 
birds having been brought by M. Dclattre, by whom I imagine my 
skins of this species were collected from that quarter. We have 
therefore four very similar but yet distinct species of these birds, 
each inhabiting a different region of tropical America; an addi- 
tional instance to the thousand others existing, of that remarkable 
law, by which we find different geographical localities tenanted by 
different yet closely allied and corresponding ornithic species. The 
four above mentioned birds are alike in the upper plumage and 
breast-band of a shining golden green, but may be distinguished 
at once by examination of the tail-feathers. Taking them geogra- 
phically, the most northern species first, we have — 
1. G. melanogenia, from Veragua; 4 medial rectriccs green, 3 
next on each side pale rufous brown. 
2. G. rujicauda , from Trinidad, Tobago, Venezuela; 2 medial 
green, others wholly rufous brown. 
3. G. ririd is, from Cayenne, Amazons ; rectriccs beneath nearly 
uniform blackish-green. 
4. G. maculicauda , from S. Brazil, Bolivia ; outer rectriccs rufous 
brown with blackish blotches at the extremities.
