slighter grounds. It looks as if it might prove to be a geo- 

 graphical variety of H. osculans.

XXXVI. — Notes on the Specimens in the Berlin Museum col- 

 lected by Hemprich and Ehrenberg. By H. E. Dresser, 

 F.L.S. &c., and W. T. Blanford, F.R.S. &c. 



In September 1873 we were working conjointly at the genus 

 Saxicola, and arranged to spend our holidays on the Conti- 

 nent together and utilize our spare hours in examining the 

 types in several of the continental museums. Most of our 

 time we spent in Berlin ; and when working in the museum 

 in that city we thought that a critical examination of the 

 types of Ehrenberg, being the collection made by Hemprich 

 and Ehrenberg, which is deposited in the Berlin Museum, 

 might prove of use ; we therefore carefully examined them. 

 We may here state that we took with us a large series of 

 Warblers (Sylviida) and Chats (Saxicolidse) for comparison; 

 amongst the latter were most of Canon Tristram's types. As 

 almost all ornithologists are doubtless aware, descrijjtions of 

 the various species considered to be new were published by 

 Ehrenberg, after the death of Hemprich, in Hemprich and 

 Ehrenberg's ' Symbolae Physicse. Aves' (Berlin, 18.29), the 

 descriptions being chiefly given in footnotes to this work. 

 The pages are not numbered; thus the following references 

 are only to the folios : — 



Lanius nubicus, Licht., Ehr. fol. e. The type agrees 

 closely with Sharpe and Dresser's plate in the 'Birds of 

 Europe,' part ii. 



Lanius isabellinus, Ehr. fol. e. In the collection arc 

 three specimens from Gumfudde and one from Arabia, all in 

 winter dress, none having the red of the head developed. 



Ardea ibis, Hasselquist, Ehr. fol. /. One specimen. 

 No. 74, from Nubia, is an immature bird of Ardea bubulcus, 

 No. 10132 in Gray's ' Hand-list.'
