Except that the general colour is decidedly paler, a specimen from 
Panama agrees with a typical example of this bird received from 
Dr. Cabanis. The Wren collected by Mr. Fraser at Escuintla, cata- 
logued (Sclater, Am. B. p. 20) as 7’. albipectus, really belongs here ; 
and Salvin has also many examples from Guatemala.

_ T. nigricapillus’, Lawr. (nec Sel.) /. ¢. vii. p. 293. 
T. castaneus, Lawr. /. c. vil. p. 321. 
Closely allied to 7’. nigricapillus, Sclater, from Ecuador, but di- 
stinguishable by the chestnut colouring below, where the adult be- 
comes almost immaculate, the black bars wearing off.

This species is clearly a Thryothorus, allied to the preceding SpeGteHy 
me of the Pheugopedius group.

We are somewhat at a loss what to call the Panama House-Wren, 
as it agrees more closely with the true aédon of North America than 
with the Guatemalan and Mexican representative. The colouring 
of the under plumage is much paler than in 7’, Aypaédon, and the 
bars on the sides are clearly shown, while in the latter species they 
are hardly visible, although not absolutely wanting as Sclater’s de- 
scription would indicate. In all the so-called species this charac- 
teristic is subject to considerable variation, as is also the marking on 
the back. The bill of the Panama bird is the longest, and in this 
respect resembles rather 7’. aédon, We still require further materials 
to separate or unite the several birds which have been described 
under the names of 7’. aédon, Vieill., 7’. hypaédon, Scl., and T. in- 
termedius, Cab. 
Mr, Lawrence also mentions the following species of this group :— 
Thryothorus rutilus, Vieill., a Trinidad species, and Cyphorhinus phi- 
lomela, Salv., of Central eee a 
Fam, Moraciuuipa.
