which he described from Lenkoran in the Caucasus. It is a 

 very vague and unsatisfactory description ; but if anything 

 can be made of it at all, I agree with Dr. Hartert in thinking 

 that intermedius must be referred to the dubius group of 

 Ringed Plovers — and this in more senses than one. I have 

 been very courteously asked by Dr. Hartert to give a name 

 to this tundra race of Ringed Plover, and I propose the 

 above name.

Mr. E. C. Stuart Baker exhibited specimens of a new 

 subspecies of Lark, which he proposed to call 



Mirafra cantillans williamsoni, subsp. nov. 

 He made the following remarks : — 



" The subspecies of Lark which I now exhibit I propose 

 to name alter Mr. W. J. F. Williamson, who discovered 

 it at Bangkok, Siam, where it is said to be common. It 

 is nearest not to typical M. cantillans from West and 

 Central India, but to M. philippensis from Manilla and the 

 Philippines. 



" From M. cantillans it differs in being much smaller, 

 with a wing varying between 68 and 73 mm. as against 77 

 to 82 in that bird. The upper surface is very much darker 

 and the lower surface also decidedly so. In Mirafra can- 

 tillans cantillans the general tone of the upper plumage is a 

 rufous sandy, the pale edges of the feathers dominating the 

 dark centres ; in M, c. williamsoni the general aspect of the 

 back is dark brown, the edges to the feathers being much 

 narrower and grey or grey-brown in tint. 



" From M. c. philippensis it differs in being rather paler 

 and less black above and in being decidedly darker and 

 duller in tint below. Every specimen in the series also 

 shows some rufous on the breast and flanks which is never 

 present in M. c. philippensis, and there are also fewer black 

 markings on the breast and lower throat than there are in 

 that bird. 



" The types of the new subspecies are
