Corresponding measurements given in 



Smith's ' South African Zoology ' of 



" Drymoica terrestris, male " 2 1 10 4| 



Eleven of the specimens from Damara Land included in the 

 above Table were measured in the flesh by the late Mr. An- 

 dersson j the remaining measurements were taken by myself 

 from dried skins. 



I may add that the coloration of different individuals of 

 this species varies much both in Trans Vaal and Damara Land 

 as regards the intensity of their tints, which I suppose to be 

 owing to the plumage becoming faded as the season of moult- 

 ing approaches. 



To refer, in conclusion, to another matter, I regret to find 

 that in the earlier portions of my list of Natal birds, pub- 

 lished at various times in ' The Ibis/ some errors of identi- 

 fication occurred, which a better knowledge of the ornithology 

 of the district has enabled me subsequently to rectify in 

 several instances (vide Ibis, 1864, p. 356, 1868, pp. 51, 147, 

 151, 155, 157, and 265, 1869, pp. 296 and 299, and 1871, 

 p. 103) ; and I am now desirous of recording the following ad- 

 ditional corrections, which I give in the order in which the 

 several species were included in my former lists. 



6. Gyps fulvus should stand as G. kolbii (Daud.), as to 

 the distinctness of which see Mr. Blytlr's remarks in ' The Ibis * 

 for 1870, p. 157. 



S4. Alcedo quadribrachys should be A. semitorquata, 

 Swains.
