[§ 4667. One—* Spitsbergen.’ From Herr H. Mechlenburg, 
of Flensborg, through Dr. Baldamus, 1861. 
Proc. Zool. Soc. 1861, pp. 400, 401. 
The Doctor wrote to me that he got this from the lately deceased Apothecary 
Mechlenburg, of Flensborg, who had received five or six with birds from a 
whale-fisher who had obtained them in Spitsbergen. This egg I exhibited 
at the meeting of the Zoological Society on the 10th of December, 1861; but 
in the absence of more precise information concerning it I forebore to have it 
figured. |
