1874.] LARKS OF SOUTHERN AFRICA. 623 



075-0-8 in length of bill ; while in the male the wing is 3-95-4-4 

 and the bill O9-0-95. It will be noticed that the three males last 

 measured in the Table are very much bigger than the first two ; 

 but even these do not agree together in size of bill. The males 

 numbered 1 and 2 agree with Mr. Monteiro's bird in having the bill 

 much thinner than any of the others ; but such a gradual gradation 

 exists in the series that I do not see ihe necessity of creating 

 another species, since the more I study Larks the more I fiud that 

 size of bill goes for very little.
