74 BANGS — NOTES ON TANGARA GYROLOIDES. [? 22°: 
(P. Z.S., 1911, 1104) was the next reviewer of the species. Care- 
fully comparing specimens of the various races, and weighing the 
results with Swainson’s description, he decided that Peru was 
an error and substituted Colombia as the type locality of the 
species. Lafresnaye’s name was a substitute one, and of course 
the type locality reverts to Swainson. In this paper, then, 
Hellmayr called the Colombian bird Calospiza gyroloides 
qyroloides (Lafr.), and named as new two other forms, the Peru- 
vian, C. g. catharinae after his wife, and the Central American, 
C. g. bangsi after me. He also called attention to the slightly 
different race inhabiting western Ecuador, which he did not 
name because he thought it too close to bangs?, and that possibly 
bangsi ranged continuously from Costa Rica to western Ecuador, 
west of the range of C. g. gyroloides in Colombia. He was fol- 
lowed in this arrangement by Berlepsch in his ‘ Revision der 
Tanagriden,’ Berlin, 1910, and by Brabourne and Chubb in 
their ‘ List,’ 1912. 
In thus shifting the names and type localities Hellmayr may 
be right, but I think it a little high-handed. Swainson named 
other Peruvian forms from the collection of W. Hooker, showing 
Hooker had birds from that country. Also, it seems to me, 
Swainson might very well have described the lesser coverts 
exactly as he did, had he had an immature male or a female 
before him. Under the circumstances, I prefer, not without 
reluctance, however, to follow Hellmayr myself. Future orni- 
thological critics must judge this rather peculiar case for them- 
selves, and will, I think, be as likely not to agree with Hellmayr 
as to follow him. 
The species appears to be rare in Panama. W. W. Brown, Jr., 
when collecting for me at Loma del Leon and near Panama City, 
did not take it, and the only specimens from the line of the 
Panama Railroad I have seen are a pair in the Museum of Com- 
parative Zodlogy, received years ago from James McLeannan. 
The male is a fine old adult, and is intermediate between the 
Central American bangsi and the Colombian gyroloides, though 
decidedly nearer the latter. Its lesser wing coverts are green, 
slightly tinged with yellowish, not yellow as in bangsi, but a
