18/9.] BIRDS FROM ANTIOQ.UIA. 509 



ton. It is of the size and structure of O. montezumce, from which, 

 and from O. bifasciatus Mr. Cassin has accurately pointed out its 

 differences in a footnote {op. cit. p. 138). 



The Paris specimen is from the Magdalena valley {Fontanier), 

 that of Cassin from the river Truando ( Wood) . 



139. Ostinops atrocastaneus, Cab. Journ. f. O. 1873, p. 309. 



Envigado, Concordia, Frontino. (Mus. P. L. S. and S.-G.) 



Iris red. 



Eggs (no. 113) reddish salmon-colour, blotched and spotted with 

 large burnt-sienna spots chiefly at the larger end. In some speci- 

 mens the spots are smaller and darker ; in others the ground-colour 

 is much darker and the spots paler and more diffused : axis 1*46, 

 diam. 1.05. (See Plate XLIII. figs. 1, 2.) 



Dr. Cabanis has, we think, fairly distinguished this form from the 

 allied O. atrovirens. Specimens from Ecuador {O. atrovirens, Scl. 

 P.Z. S. 1859, p. 140, et 1860, p. 88, nee d'Orb.) are apparently 

 similar; but the Bogota bird {O. sincipitalis, Cab. I. c.) is not quite 

 so darkly coloured, although nearer the present form than to the 

 southern O. atrovirens.
