" Enrique Arce." Collection of Mr. ( >. Sal Tin. 



Mr. Salvin (P. Z. 8., 1867, p. 135) states that Mr. Sclater 

 and himself had compared this species with the type Bpeciraen 

 of T. tessellatus, Lair, et D'Orb., from the Museum d'Histoire 

 Xaturelle of Paris, and found no "appreciable differences." 



In the Lafresnaye Collection, now in the Muse nm of the 

 Boston Soc. of N". H., are two specimens of T. tesselatus marked 

 "type;" a comparison with these showed the two 3p 

 quite distinct. The color si tessellatus above [sofa darker 

 brown with more of a reddish cast, the entire ander-plum 

 is of a reddish fulvous brown, whereas T. inquiet/us has the 

 throat, breast, and upper part of abdomen white, tinged with 

 fulvous, and above has a tinge of olive ; the wing of U 

 is much longer. 



I do not know how to reconcile the difference betw< i n I 

 specimens in the Lafr. Coll. and the one in the Paris Museum, 

 except by supposing the latter to b<' incorrectly labelled -tin 

 fore for the present I must adhere to the probable accuracy 

 Baron Lafresnaye's types in his own collection : his sp< 

 came from Peru.
