and this pteryla is quite broad, as it is continued on to the tail, 
the whole system of the pterylography causing the feathering 
to be quite dense in this species. 
Both the form of the body and its pterylography in Regulus 
is substantially repeated in Polzoptila plumbea, a specimen of 
which species I have this moment plucked, and now have before 
me. In it, however, there is an evident arrangement of the 
feathers in the capital area; for a strong, single, median row 
can be easily recognized, and another single row passes over 
each eye. The median row bifurcates anteriorly, the base of 
the culmen passing between the limbs, which latter have on 
either side the lateral orbital row merging into it. Judging from 
form of body and pterylography alone, I would hardly say there 
was any very close affinity between Chame@a and the last two 
genera we have examined. 
In the lot of alcoholics kindly collected for me by Mr. Coale, 
I also find an excellent specimen of Certhia famtliaris amert- 
cana; but aside from its curved and slender beak, the form of 
the body of this species is sylvicoline, with troglodytine affini- 
ties quite pronounced, while its pterylography is strictly pas- 
serine. From its topographical anatomy, and what we know of 
its habits, it surely has but a very slender kinship with Chamea. 
The pterylography of Certhza familiaris has been correctly 
figured by Nitzsch.} 
Passing next to one of our specimens of Accentor modularis, 
I find upon plucking it that its pterylography is very different 
from Chamea, having quite the same pattern which Nitzsch 
figures for Motacilla alba,? though in Accentor the saddle tract 
of the dorsum is if anything proportionately larger, and the 
pteryla leading from it to the uropygial gland broad, and spread- 
ing posteriorly at its termination. All the pteryle are clearly 
defined and strong in the Accentor. 
The form of the body in this bird is what one might suppose 
to be as across between one of our average Sparrows and a large 
Warbler, say for instance, D. vigorsiz x Ammodromus, at once 
noticeably different in contour from the subject of our paper. 
An arrangement of the feathers on the top of the head in this 
species are as I described them for Polopizla, with the exception
