THAMNOPHILUS. 199 



T. punctatus was described by Dr. Cabanis from a specimen sent from Costa Rica by 

 Dr. HoflPmann, and made the type of a group Abalius ^. 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 naw contains several examples *. In the 

 portion of the State of Panama adjoining Costa Rica this bird would seem to 

 be more numerous, as Arce 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. 



y. Minor : rostrum debile ; ptilosis plerumque saturate cinerea albo striata ; alee magis 

 elongatoe, remige secundo longiore ; sexus similes.

 Panama, David {Bridges i), Mina de Chorcha ^, Bugaba *, and Bibalaz (Arce). 



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 T. uigriceps, 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 Panama ^. Arce subsequently procured us several 

 specimens near the same place *, and it has also been traced to Costa Rica ^ ^. 



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.
