Prof. Newton, was reviewed by Strickland in the January 

 number of the 'Annals of Natural History ' for 1842 (vol. viii. 

 p. 362), was most likely pul)lished in the later months of 18fl; 

 and if Bonaparte's '^ Introduzione '^ to the Birds w^as pub- 

 lished in the earlier months of the same year, Gray may have 

 had time to see it before the publication of his ' List/ 



But, again, how was it that Gray in his ' List'' gave to the 

 genus Chettusia, Bp., the date 1839? Unless Bonaparte 

 has published that generic name in some other work, which 

 we do not know^, the only explanation 1 can give is this : — 

 The Dedication of Bonaparte's ' Iconografia ' to the Grand 

 Duke of Tuscany, Leopold II., which is placed after the 

 frontispiece of the first volume of the work, is dated 1839 1> 

 and most likely Gray took that date for that of the " Intro- 

 duzione " also. 



I think that after all this we may be satisfied that the 

 " lutroduzione'*'' to the Birds of Bonaparte's 'Iconografia della 

 Fauna Italica ' was published in the same year in which the 

 work was completed, namely in 1841.

XXXIII. — Notes on the Emperor Penguin (Aptenodytes 

 forsteri). By P. L. Sclater, M.A., Ph.D., F.R.S. 



The interest which I have taken in the proposal to send out 

 another exploring expedition to the Antarctic Seas has 

 induced me to look up what is known of the history of 

 the Emperor Pcuguin, the giant of the group to which it 

 belongs, and a characteristic lorra of the little-known Ant- 

 arctic continent. So far as I can make out, this bird has 

 only been met with on tin-ee occasions, — (1) by Cook, in 



* Also as regards the genits Otocorys, Bp., it is generally stated to 

 have been established in the " latroduzioue ;" but 1 have found out quite 

 lately (Cy. ' Eleuco degli Uccelli Italiaui,' p. 303) that it was proposed iu 

 the ' Nuovi Aunali delle Sc. Nat.' (Bologna), ii. p. 407 (1830;. 



t It seems that Bonaparte published the Dedication of his work to the 

 Grand Duke of Tuscany, Leopold XL, on the occasion of the Meeting of 

 the Italian Savants held at Pisa, in 1839.
