Hab. Panama, Calovevora 2, Chitra 1 2 (Jrce). 



Of this pretty species we have as yet only seen the two original specimens sent us by 

 Arce in 1868, and described in the 'Proceedings' of the Zoological Society for that 

 year. Both these specimens are marked as females, so that the male is not yet known, 

 but it, in all probability, is quite similar to the female in its plumage. 



In its long slender tarsi and delicate feet this species resembles Leptotriccus sylviola 

 of Brazil, and it also has the pointed wings and long tail of that bird ; the bill, however, 

 is somewhat larger and wider. 



The distinct chestnut superciliary streak over each eye is a strongly marked charac- 

 teristic feature of L. superciliaris. 



POGONOTEICCUS. 



Poffonotriccus, Cabanis & Heine, Mus. Hein. ii. p. 54 (1859) (type Muscicapa eximia, Temm.) ; 

 Scl. Cat. Birds Brit. Mus. xiv. p. 97. 



Mr. Sclater recognizes four species as belonging to this genus, its range extending 

 from Costa Eica to South Brazil. 



The general colour of all the species is bright olive above and yellowish beneath, 

 the head varying from grey to dark plumbeous. The bill in P. ewimius narrows 

 rather abruptly, the width at the rictus being considerably more than half the length 

 of the tomia ; the culmen is gradually curved from the forehead, more rapidly towards 

 the tip ; the rictal bristles are very fully developed ; the tarsi are rather short and 

 slender, the enclosing scutellse almost obliterated into one shield ; the feet are feeble, 

 the outer and middle toes being nearly equal, the inner one shorter. The wing is 

 rounded, the 3rd quill a little < 2nd and 4th, 5th = 2nd, 1st = 9th ; tail rather long 

 and square, the feathers narrow, a little < wing, > 3 times tarsus.

We have never obtained a specimen of this species, but have taken our description 

 from the type of the female lent us by Mr. Lawrence. This bird has a close ally in 

 P. plumbeiceps, Lawr., of Colombia, but the bill is rather wider, the mandible paler,
