slighter grounds. It looks as if it might prove to be a geo¬ 
graphical variety of H. osculans. 
My specimen, , a type (Jelski), Maraynioc, Peru, was 
presented to me by M. Taczanowski. 
XXXVI.— Notes on the Specimens in the Berlin Museum col¬ 
lected by Hemprich and Ehrenberg. By II. E. Dresser, 
F.L.S. &e., and W. T. Blanford, E.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 (Sylviidse) and Chats (Saxicolidse) for comparison; 
amongst the latter were most of Canon Tristram's types. As 
almost all ornithologists are doubtless aware, descriptions of 
the various species considered to be new were published by 
Ehrenberg, after the death of Hemprich, in Hemprich and 
Ehrenberg's f Symbolse Physicse. Aves' (Berlin, 1829), 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 nubicxjs, Licht., Ehr. fol. e. The type agrees 
closely with Sharpe and Dresser's plate in the f Birds of 
Europe,' part ii. 
Lanius isabellinus, Ehr. fol. e. In the collection are 
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. 1. One specimen, 
No. 74, from Nubia, is an immature bird of Ardea bubulcus, 
No. 10132 in Gray's f Hand-list.'
