RICHARD'S PIPIT. 143 



we are most familiar, its dimensions are as 

 follows : 



Hind toe 

 Bill. Wing. Tarsus, with claw. 



Inches. Inches. Inches. Inches. 



A. obscurus . . "5 . . 3*2 . . *9 . . '8 

 A. Richardi . '6 . . 3*6 . .1*2 . .1*2 



Its occurrence in England has been noted, as 

 might be expected, chiefly on the east and 

 south coasts, in every month between September 

 and April, both inclusive. At least fifty speci- 

 mens have been seen or procured, distributed 

 as follows : Northumberland, 2 ; Norfolk, 5 ; 

 Shropshire, i; Oxford, i; Middlesex, 12; 

 Kent, 3 ; Sussex, 5 ; Devonshire, 1 1 ; Corn- 

 wall and Scilly, 8. In the west of England, 

 therefore, it would appear to be very rare, and 

 in Ireland it is unknown. 



The most northern locality, I believe, whence 

 this species has been procured, is Heligoland, 

 on which island, according to Professor Blasius, 

 it is said to have been obtained by Herr Gatke. 1
