In the last volume of ' The Ibis ' (p. 153) we confessed our 

 inability to find the original reference to Cyanocephalus 

 wiedi, Bp. We have since discovered it in a small brochure 

 published by Bonaparte in Florence in 1842, and called 

 " Osservazioni sullo stato della zoologia in Europa in quanto 

 ai Vertebrati nelF anno 1840-1841, lette li 27 Settembre 

 alia terza riunione degli Scienziati Italiani da Carlo Luciano 

 Principe Bonaparte," &c. 



In speaking casually (p. 17) of Gymnorhvnus cyanocephalus, 

 Wied, he says : — " I/ultima delle quali costituisce un genere 

 a se, per cui mi veggo costretto a proporre il nome di Cy- 

 anocephalus come generico, quello datogli dal fondatore tro- 

 vandosi gia inipiegato." No characters are given. 



We may here add a further reference to Bonaparte's 

 writings which has escaped Dr. Coues's search, who, in 

 reviewing the literature of the subject, in an exhaustive memoir 

 on the Spheniscidae, recently published in the ' Proceedings 

 of the Academy of Natural Sciences of Philadelphia ' (1872, 

 p. 170 et seq.), writes as follows : — 



" 1850-56. Bonaparte, ? I do not know where this 



author has treated of the Penguins ; and none of the authorities 

 quoted give any reference. According to quotations, he 

 has instituted a genus Eudyptila upon Aptenodytes minor, 

 Forst., and has renamed the two species of Aptenodytes 

 that Gray named fosteri and pennanti, calling them imperator 

 and rex respectively. There is no excuse whatever for this." 



The reference is evidently to the ' Conspectus Ptilopterorum 

 Systematicus/ appended to the ' Tableaux paralleliques des 

 Pelagiens ou Gaviae/ published in the ' Comptes Rendus ' for 

 1856, xlii. p. 775. 



In this Conspectus the Spheniscidae are divided into two 

 subfamilies — Spheniscinse and Dasyrhamphinae, the former 

 being again subdivided into Aptenodyteae, with the following 

 genera — 1. Aptenodytes, 2. Eudyptila, 3. Chrysocoma, and 

 4. Pyyoscelys and Spheniscese with the genus Spheniscus, — 

 the latter containing the Dasyrhamphese with the single genus 

 Dasyrhamphus. 



Eudyptila (of which no characters are given) contains
