number, all of which I have examined. I have by this 

 means sometimes come across some curiosities, as, for in- 

 stance, the Dodo in the picture by Franz Francken, 1581- 

 1643, must have been added to it after his death by another 

 artist in or after 1666. 



Blumeubacli, 1799, as well as Brandt, 1847, give their 

 own drawings of the Dodo, both based on ancient pictures 

 as well as on the cast of the head in tbe Oxford Museum. 

 Unfortunately this skull wants the characteristic horn- 

 sheaths, so that their drawings are wrong. 



Von Hayek gives, in his Handbuch der Zoologie, a figure 

 of a Dodo. In the lower left corner you will observe a 

 fictitious monogram of Roelandt Savery : R and S crossing 

 each other, and under the figure the inscription, '' Nach 

 Savery's Bild in Wien." — The one and the other are wrong, 

 for Savery^s monogram and his picture in Vienna are quite 

 different, and, moreover, Hayek's figure is for the greater 

 part a copy of Brandt's drawing of 184^7, amended by 

 himself in the wing, the region of the rump and the tail after 

 Edwards's reproduction of the picture of Roelandt Savery in 

 the British Museum ! 



As to the Common Dodo {Eaphus cucullatus L.) the males 

 and females differ widely in colour and in ornaments. The 

 males are light bluish-grey with a plume-like tail, which 

 gradually passes into a rich dress in the region of the sub- 

 caudal coverts and circumanal feathers. The females are 

 blackish-brown, with a brown breast and an almost globular 

 tail like that of the Ostrich. 



In the nuptial dress the Dodos remained from March to 

 September, and in this period they were extremely fat ; on 

 the other hand, from September up to March they had a 

 more erect carriage, as is represented on the gable-stone — 

 meagre, long-legged, with outstretched neck. 



The figure of Clusius (1605) shows the bird during its 

 moult. Between these three states we find, of course, por- 

 trayed all kinds of intermediate stages. I have at present 

 in my collection 85 reproductions taken from 38 originals, 

 showing these stages.
