 sternum. In all particulars, the sternum appears to be typically 

 fringilline. 



Conclusions. The details of anatomy here given throw very 

 little light on the affinities oi Chloiophonia but there is no special 

 relationship to the tanagers shown. The palatine structure and 



the peculiarities oi the alimentary canal both tend to separate it 

 from that group. 



Ki PHONIA. 



An adult male oi Euphonia minnta from Costa Rica has been 

 available for study ami comparisons have been made chiefly with 

 Chlorophonia. The bill and feet Deed no discussion here; the 

 character of the tarsal covering in Euphonia has been described 



above under Chlorophonia. 



Tongue. The tongue of Euphonia is strikingly different from 

 that of Chlorophonia or any of the tanagrine birds 1 have examined 

 and resembles that of some of the Coerebidse. It is almost tubular, 

 the sides being rolled inward but not quite meeting. The tip is 

 brushy. 



Pterylosis. The general plan of the pterylosis is not peculiar. 

 The dorsal saddle is more nearly rhombic than in Chlorophonia 

 and the Other tracts are not so broad nor so densely feathered 

 as in that genus. The arrangement of the nine primaries is essen- 

 tially the same, but the eighth is slightly the longest and the ninth 

 is a trifle longer than the sixth. There are twelve nearly equal 

 rectrices. 



Alimentary Canal. The genus Euphonia has long been noted 

 for the apparent absence of a stomach. The specimen at hand 

 does not seem to differ essentially from the one figured by Forbes 

 (1. c). The intestine is very long, about ISO mm., or twice the 

 total length of the bird, ami is much convoluted, as in Chlorophonia. 



Palatine Region. The palate o( Knphonia has been figured by 

 Parker (Trans. Zool. Soc. London, vol. 10. pi. 46, fig. 3) and the 

 specimen before me agrees well with that figure except for the 

 apparent absence of maxillo-palatines. Parker indicates these 

 bones rather indefinitely and 1 have found nothing that seems to
