Mr. T. Ayres on the Ormtliology of Transvaal. 351 



These measurements are, for tlie most part, somewhat less 

 than those of four European examples with which I have 

 compared them, and which I find to be as under : —

I think it also worthy of remark that the three South- 

 African specimens which I have marked as B, C, and D, 

 though in full breeding-dress, show no trace of the white 

 line immediately above the eye, wdiich is usual in British 

 specimens w^hen in full plumage, and which has only been 

 absent in one such example that I have examined, a Noi^folk 

 specimen killed in August, when the nuptial dress was no 

 longer at its fullest. 



Unfortunately^ the tw^o South-African skins which I re- 

 ferred to in '^The Ibis^ for 1869 are not now in my possession, 

 and I am unable to say whether the white superciliary line 

 was absent in them also. — J. H. G.] 



PoDiCEPS MINOR (Liuu.). Little Grebe. 



Male, Potchefstroom, 12th August, 1883. In very nearly 

 full breeding-dress. 



This species, though by no means numerous in the Trans- 

 vaal, breeds there in suitable localities, but shows itself more 

 in winter than in summer. 



[I have examined two skins of this species from Natal 

 and two from Transvaal, all of which exhibit a slightly 

 greater amount of white on the secondaries than is usual in 

 British specimens,, but less than I have found on the secon- 

 daries of an Indian example which I have also examined. —
