across any of these little birds^ although we searched diligently 

 for them during three days. 



In habits and manner of life P. kansuensis is not distin- 

 guishable from other Pyrgilaudce. It also frequents burrows ; 

 but these, instead of belonging to the Lagoniys, of which there 

 are none here, are the dwellings of a species of Spermophilus. 

 Its flight is low,uudulatory,and generally to no great distance.

 lengthwise ; the other rectrices are black. The outer web of 

 the outermost pair about halfway up has a white margin.
