 marked narrow dark shaft lines on back ; greater wing coverts and 

 exposed parts of scapulars, secondaries, upper tail coverts and top of 

 tail bright rufous chestnut, dullest on wings; greater coverts with 

 blackish shaft lines; primaries edged externally with rusty brown, 

 shaded with olive ; sides of head and neck, including malar region, 

 brown like top of head and marked with a supraocular stripe ex- 

 tending back to nape; ring around eyes and streaks along sides of 

 head and neck pale yellowish white ; chin and throat white ; rest of 

 under parts nearly uniform olive brown (with a slight tinge of

 numerous bright yellowish white guttate spots sharply edged with 

 black, the spots largest along median line, smaller on sides and be-

Measurements of type. — Wing, 76; tail, 71 ; oilmen, 14.5; tarsus, 

 20. 



Remarks. — This well-marked species is nearest perlata but appears 

 to be distinct from any heretofore described. The spots on the under 

 parts resemble those of perlata but are much smaller and fewer and 

 the general color of the under parts is browner and less washed with 

 rufous. On the back the two are very distinct. This species is 

 based on six specimens, all from Mount Pirri. In some specimens 

 the dusky shaft streaks on the back are much more prominent than 

 in others and one specimen has a few small scattered yellowish white 

 shaft streaks on the posterior part of the neck or extreme !'n 1 

 the back.
