not belong to this subgenus, and is to be placed in the neighbourhood 
of rufinus, Spix, and cireumcinctus, Sw., which have the same bill 
and similar covering. 
We have only two species, pitangua and chrysocephalus, Tchudi, 
in the section of Scaphorhynchus. 
Scaphorhynchus, with its broad bill, shorter and feebler tarsi and 
toes, represents more the Swallow type, and must be placed in the 
second rank of his genus. 
Before I finish I may allow myself the observation, that, till now, 
the whole family of Muscicapide has been in a condition of the great- 
est confusion, and that the greatest number of genera must go down, 
or must be considered as subgenera of some larger genera. As an 
example of the way in which this is to be effected, I give for instance 
we eee Psaris, into which I transplant three genera of the new 
authors. 
Some remarks on the genus Psarts, Cuv. 
The genus Psaris, which is synonymous with Tityra, Vieill., is a 
true genus, which cannot be considered as the only type of a sub- 
family, and which cannot be divided into several genera. It is an 
indivisible genus, which I have separated into some little subgenera 
only. I prefer, from well-known reasons, the name Psaris. 
The characters of this genus are :—Thick, strong, slightly com- 
pressed bill, without strong bristle-feathers on the mouth gape; tarsi 
moderately high, with broad scales on the front; on the sides and 
behind with small scales. The old males have the second hand wing- 
feather abnormously short and of an unusual formation. The females 
and young birds have the wings regular. 
The species of this large genus are limited to the southern parts of 
America. 
a. Subgenus CHLOROPSARIS. 
They have the bill and the feathered lorum of the Pachyrhamphus, 
but the wings are shorter and the tail more graduated. Size of a 
Sparrow, colouring more variegated and greenish on the back. 
1. Psarts Cuvrert, Swains. Spix, tab. 45. 2. 
2. Ps. arRicapityus. Muscicapa, Gmel. Enl. C. 871g. 831 2. 
3. Ps. versicotor. Vireo, Hartlaub. 
b. Subgenus PacuyrHamPuus, G. Gray. 
The bill unicolor black, shorter than the head, not compressed on 
the sides; the bristle-feathers moderately long ; the abnormous hand- 
feather like Chloropsaris, with broader inner webs and emarginated 
only on the tip; tail unicolor, very little graduated. Size of a Lanius 
colurio. The colouring is dark and not so variegated. 
We can give by the diagnosis the colouring of the abnormous hand- 
feather of the males.
