both, the form, size, bill, and general faczes were considerably 
like Chamea. It was also interesting to note that these birds 
had the flight-feathers of the wings indistinctly barred, as we 
so often find them among certain troglodytine types. 
Mr. Lucas has published it as his opinion “that Chamea 
appears most decidedly to belong with the Wrens, and not with 
the Titmice.” (voc. 7. S. Nai Mus., 1888; p. veo) imally, 
Mr. J. A. Allen, in a letter to the writer under date of June 14, 
1880, says, “I know of no South American forms near Chamea, 
outside of the Wrens, of which South America furnishes a large 
and varied assortment.” 
With these facts before us, it would seem that a careful com- 
parative study of the structure of Chama could be nothing less 
than a well-chosen task, and one decidedly worthy of the labor 
required to complete it. It is such a work that I have to present 
in the present paper, and I am indebted to a number of my 
friends for material wherewith to prosecute it. Chief among 
these it gives me pleasure to thank Mr. F. Stephens, of Ballena, 
California, for upwards of a dozen specimens of Chamea fasciata 
henshawt, and adult and young of Yhryothorus 6. spilurus ; this 
material was collected for me by Mr. Stephens, and generously 
donated by Mr. G. Frean Morcum, of Chicago. They were all 
alcoholics. Ten or twelve years ago I also received a good 
skeleton of Chamea fasciata from Mr. C. A. Allen, of Nicasio, 
California, and my thanks are due to the same naturalist for a 
specimen of Parus rufescens in alcohol. Mr. Herbert Brown, of 
Tucson, Arizona, sent me a series of beautiful specimens of 
Auriparus flaviceps and Campylorhynchus brunneicapillus, which 
yielded some excellent skeletons, for which I was especially 
grateful. My valued friend, Professor Alfred Newton, F.R.S., 
of Cambridge, England, generously sent me alcoholics of adult 
g and 9, and juv. of Accentor modularis, which were suggested by 
him to be compared in the same connection. It was also through 
Professor Newton’s kindness that I obtained from his friend, 
Lieutenant W. Wilfrid Cordeaux, of the 2d Dragoon Guards 
(Queen’s Bays), some fine alcoholic specimens of the Paride 
of the Northwestern Himalayas. Still later I was favored by 
Dr. George Bird Grinnell with a specimen of Pertsoreus canaden- 
sts capitalis, with which I intended to make some comparisons of 
the skeleton between it and representatives of the sub-genus
