THAMNOPHILUS. | 199 
T. punctatus was described by Dr. Cabanis from a specimen sent from Costa Rica by 
Dr. Hoffmann, and made the type of a group Adalius!. ‘The species, however, appears 
to be rare in that country, as only a single specimen has reached us, and Mr. Zeledon 
had none before him when he compiled his first catalogues of the birds of Costa Rica ; 
but the National Museum of Costa Rica now contains several examples*. In the 
portion of the State of Panama adjoining Costa Rica this bird would seem to 
be more numerous, as Arcé found it in some numbers in the neighbourhood of 
Chiriqui °, and all but the Costa Rican example already mentioned which have come 
before us are from his collections. 
Nothing has been recorded of the habits of this species, which is doubtless a denizen 
of the dense forest of the countries in which it is found.

This Thamnophilus has no near allies, the white stripes covering the whole head and 
the under surface of the body rendering it distinct from all the other members of the 
genus except 7’. nigriceps, which again is reddish brown where T. bridgesi is dark grey 
and has the wings and tail chestnut. 
It was first described by Mr. Sclater in 1856, in his paper on Bridges’s collection 
made near David in the State of Panamat, Arcé subsequently procured us several 
specimens near the same place 4, and it has also been traced to Costa Rica 5 6. 
Bridges stated that he found only one individual of this bird in the thick bush on 
the margin of the river near David!. This he shot, and this is the specimen described 
by Mr. Sclater, and is now in the gallery of the British Museum.
