94 NEW BIRDS FEOM VENEZUELA 



Myiopsitta liueola (Cass.)? 



Three adults and one young of what i>s apparently this species, or one 

 very closely related, were foiiud attached to the belt and removed. 

 The young example I am unable to distinguish satisfactorily from speci- 

 mens of the Mexican bird in the same stage, of which there are three 

 in the National Museum collectiou, but, unfortunately, no adults. The 

 type of PsUtacula Uneola Cass, appears to liave been immature, since the 

 description agrees substantially with the presumed young in the Na- 

 tional Museum collection. I liave endeavored to borrow the two speci- 

 mens mentioned by Mr. Cassiu, but am informed that they cannot now 

 be found in the Academy of Natural Sciences' collection. 



The points of difference between the adult and immature birds are as 

 follows: 



Adult: U[)per tail-coverts yellowish green, heavily blotched with 

 black, the blotches decidedly longitudinal; middle pair of tail-feathers 

 wholly black for the exposed portion, or else with only a very little 

 green showing along the edge. 



Younr/ : Upper tail-coverts duller and less yellowish green, each 

 tipped with a small deltoid spot of black, having a transverse rather 

 than longitudinal direction ; middle pair of tail-feathers mostly green 

 for the exposed portion, the tip and a streak along the shaft only being 

 black. General plumage less vivid, with the black bars less distinct. 



Differences are appreciable between the young bird of supposed 

 South American habitat and those from Mexico, but with only a single 

 specimen it cannot be determined to what extent the observed differ- 

 ences may be individual in character. They consist chietly in the larger 

 size and generally darker coloration of the southern specimen.
