former usually predominatijig), the black spots usually forming a 

 chain of very irregular blotches along the median Une, but sometimes 

 prolonged laterally so as to form more or less distinct, but always irreg- 

 ular or broken oblique or V-shaped bars ; second pair similarly col- 

 ored, but the black relatively greater in extent; third, fom'th, and 

 fifth pairs with terminal half (approximately) of inner web and a less 

 extent of outer w^eb, next to shaft, white, these white areas broadly 

 margined, except on edge of inner web, mth dull ochraceous-bufl: 

 or clay color, the under sm-f ace of these areas wholly tawny or tawny- 

 ochraceous; proximal portion of these rectrices black with rather 

 broad broken bars or transverse spots of light cinnamon-rufous; 

 lores russet or chestnut, the suborbital, malar, and auricular regions 

 similar but narrowly barred with dusky; chin and throat russet to 

 Hght chestnut, narrowly and rather sparsely barred with black; across

" From lack of specimens I am unable to give measurements of the adult male of 

 this form, the above description being based on adult females plus tail-markings in 

 the adult male of ^. r. otiosus.
