There is considerable difference in plumage between the adult and young in this 

 species, the latter being much less generally striated than the former, though the 

 stripes on tlie back of the neck are more pronounced. The breast, too, is much 

 more rufescent. Some of our young specimens show feathers of the adult, so that, 

 different as the adult and young are, their relationship is proved. 



There also appears to be a certain amount of individual variation between members 

 of the species. Costa Rica specimens, as a rule, are not so distinctly striped on the 

 head as some from Ecuador, but others from the latter country are not on this account 

 to be distinguished from northern examples. The most definite stripes are possessed 

 by our specimen from Colombia. 



In 1870 Salvin * stated his impression as to the identity of Mr. Lawrence's A. lineatus 

 with Mr. Sclater's A. subalaris, and on reconsidering this question Avith a much larger 

 series at our disposal, we do not think that decision should be altered. Count 

 Berlepsch, however, after examining Mr. Lawrence's type, gives A. lineatus subspecific 

 value in its relationship with A. subalaris^. But the differences of size and colour to 

 which he draws attention are hardly confirmed by our series, and we therefore place 

 both the Central-American and Ecuadorean birds under one title. 



The types of A. subalaris were obtained by Eraser near Pallatanga in Ecuador ^, and 

 were described by Mr. Sclater in 1859. Mr. Lawrence's type of A. lineatus was sent 

 by Carmiol from Angostura in Costa Rica, and was described in 1865 ''. Other 

 examples have since been procured in both countiies, and from several intermediate 

 points, but no account of the habits of the bird has reached us.
