This species is distinguished by the cinnamon-colour of the tail, and also by the 
cinnamon-rufous on the quills, and by the white belly. Count Salvadori did not 
fail to remark on the curious fact that it appeared to be identical with the Braziiian 
G. violacea, though there had been no record of the occurrence of the species in 
any intervening part of South America. He could not find any character wherewith 
to separate the Brazilian and Panama birds specifically, a single specimen only from 
the last-named locality was, however, available for comparison. We have now received 
two more examples from Mr. Underwood, and, in addition to the characters given 
above, we believe that the Central-American form can be specifically separated from 
the true (. violacea by its more vinous forehead and cheeks, and by the intense violet- 
blue on the mantle, which is much more pronounced than in the Brazilian bird. We 
had the opportunity, in 1892, through the courtesy of Prof. J. A. Allen, of comparing 
Lawrence’s type with our own Panama specimen ; the former was immature, but both 
evidently belonged to the same species. | 
Like most of the species of Geotrygon, this bird is seldom found in collections, and 
very little is known of its habits. It is recorded from Panama and Costa Rica, and in 
the last-mentioned country it is said by Mr. Underwood to be very rare. He procured 
specimens during one of his rambles on the Volcano of Miravalles, where small flocks 
of from four to six were observed in the thick woods, some being shot when feeding on 
the ground, and others on low branches of trees 3.
