PHILYDOE.— ANABAZENOPS. 161 



The original description of P. panerythrus was founded by Mr. Sclater in 1862 upon 

 a single specimen, a trade skin, from Bogota ^, but no other examples have reached us 

 from that country. Several have been sent from Costa Rica and the State of Panama, 

 but even there the bird would appear to be rare. 



Mr. Lawrence described the Costa Eica bird in 1866 as Automolus rufescens^, 

 under which name it is mentioned by Mr. Ridgway in 1884 ^ ; but in 1870 Salvin 

 referred A. rufescens to Philydor panerythrus, and we see no reason for altering this 

 decision, which was endorsed by Mr. Sclater in the ' Catalogue of Birds in the British 

 Museum ' 2. 



Nothing is on record concerning the habits of this bird.

Hah. Panama, Santiago de Veraguas {Arce ^ ^ ^}. 



The single male specimen sent by Arce from Santiago de Veraguas in 1866 is still 

 the only example known to us. 



The species is closely allied to P. pyrrhodes, a bird from Guiana and enjoying a 

 wide range in the valley of the Upper Amazons to the foot of the Andes of Ecuador 

 and Peru. From this bird P. fuscipennis differs in its darker, more rufescent rump and 

 tail, its more cinnamon-coloured back, and browner body beneath. 



ANABAZENOPS.

Anabazenops is very closely allied to Automolus and Philydor, and perhaps hardly 

 to be distinguished from them. The chief, if not the only difference, is in the shape 

 of the bill, which is slightly upturned ; this character is carried much further in Xenops, 

 so that Anabazenops occupies, as its name implies, an intermediate position between 

 Automolus and Xenops. 



The tail in some of the species is rather longer than the wing, but in others the 

 reverse is the case. 



Of the eight species included in this genus by Mr. Sclater, two only occur within 

 our limits — one of them, A. variegaticeps, having a wide range, and extending from
