(? ad. (type at' speciesj. Al)ove .and lieneatli iinilorm dark Iduish scWstaceous. 

 Wings and tail sooty blackish ; upper wing-coverts with ver}' small white a]iical 

 dots ; remiges and rectrices exteriorly slightly edged with schistaceous. Bill black. 



The specimens from Chauchamayo have rather longer bills and the lower parts 

 a shade darker ; the J from Poznzo, however, is absolutely identical with the type. 

 la all four males the under surface is uniform schistaceous and scarcely paler than 

 the back. The bill is entirely black in Nos. 1—3 ; while No. 4 has the lower 

 mandible a little paler, more brownish. 



? ad. E.xactly like that of S. s. leiicostijjma and S. s. suhphimhrii, and onlv 

 (lifiTering in the less rufesceiit, more olive-brown tint of the upper parts and in tlic 

 top of the head being of the same colour a-i tlie back (instead of dark schistaceous). 

 Tail rather longer. Upper mandible l)lackisli, lower jaw horn-Tjrown (not whitish, 

 as in the following subspecies). 



Nos. .5 and are certainly the females of the present form, although their tail 

 is rather longer than that of the males (Nos. 1 — 4). I have examined a female of 

 S. s. subphimbca with the tail quite as long.
