192. Chrysuronia longirostris, Berlepsch, Krit. Neb., 



1888, p. 20. 



//(T/^/V^?/.— Columbia, Ecuador. 



The only difference between this species and the preceding 

 one is the lenarth of the bill, which is one eighth of an inch 

 longer. I hardly think it is sufficient to consider it as a species. 



I possess two specimens collected by Buckley in Ecuador, 

 one has the tail greenish-bronze instead of reddish-bronze, 

 the other has all the underside, excepting the throat, metallic 

 gold.
