3. HYP0LAI8. 85 



bird, with a shorter second primary and a longer bastard primary. 

 The third, fourth, and fifth primaries are nearly equal and longest ; 

 the second primary is usually intermediate in length between the 

 seventh and eighth, and not unfrequently between the eighth and 

 ninth, and, in rare instances, between the sixth and seventh ; the 

 bastard primary exceeds the primary-coverts by 0*2 to 0-4 inch. 

 Length of wing 2 53 to 2-3 inches, tail 2-2o to 1"9, cnlmen 0-6 to 

 0'53, tarsus OSo to 0-8 ; outside tail-feathers 0-25 to 0-15 inch 

 shorter than the longest. 



After the auttonn moult the underpnrts are somewhat more 

 suffused with pale huffish brown than appears to be the case after 

 the spring moult ; otherwise I can discover no differences attributable 

 to age, sex, or season beyond the usual wear and tear of abrasion.
