l-U. Dysithamnus >\i. 



One fcmaie of a Di/sithamnus sliot at (.'actiavi, November 20th, l8'.1(j, is near 

 striaficejjs hawv.. Imt may belong to au undescribed form. It would, however, be 

 troublesome for future workers to desei-ibe it from a single skin and without know- 

 ledge of the TtwJc. 



r.iJ. Cymbilanius lineatus Leach. 



cf, Cachavi, November 2Tth, 1^'J(). "Iris scarlet; feet light blue: nuvxilla 

 black, mandible bluish."' The stomach contained a small frog. 



133. Myrmetherula viduata ^>^ uov. 



Two/emales from Cachavi ditier from Mi/rmetherula menetriesi, to which they 

 arc apparently nearest related, in being very much browner on the upperside, which 

 is not greyish olivaceous as in .1/. mcnctriesi, but warm olive-brown without any 

 o-reyish tinge, the rump with a rufous wash; the forehead and sides of head, on 

 the other hand, have no rnfesceut tinge, the feathers there being buff with 

 blackish brown tips. The wing-coverts have some rusty patches on their tips, 

 which are arranged so as to form two bars across the wings. The iris is marked 

 brown in one, white in the others, one of these being probably a slip. The feet 

 are greyish ; mandible whitish, maxilla black. It is a great pity that no male was 

 collected.
