The following papers were read :— 
1. On the Trichoglossine genus of Parrots, Eos, with 
THE DESCRIPTION OF TWO NEW SPECIES. By CHARLES 
Lucian, Prince Bonaparte, Member of the principal 
ACADEMIES OF EUROPE AND AMERICA. 
The genus Eos is, like Eclectus, a new instance of the impropriety 
of that middling course (as disgusting in science as it is in politics), 
of uniting together by two and two, four and four, &c., small 
groups (or States), which, natural by themselves, have no stronger 
relation to each other than to any other member of their family. 
Take for example (comparing them to Naples and Sicily!) Spiza and 
Paroaria, Bon., united by G. R. Gray under his Spiza ! amongst the 
FringillidrB, and amongst the Parrots Psittacodis* and Eclectus 
confounded together by the same process! 
The genus Eos is intermediate between the two subfamilies Tri- 
choglossince and Loriince. Although it may astonish some natural¬ 
ists that I do not consider it as one of the latter, still, on account of 
its tail, its anatomy and its habits, I keep it within the boundaries 
of the former, in close relation with my new genus Chalcopsitta f, 
* Since I speak of Psittacodis (the only green Genus of Lorine Parrots, which 
forms the same beautiful passage from Loriince to Psittacince that Eos does from 
Trichoglossince to Loriince), let me submit to the Society the phrases of two new 
species that make the whole number hitherto known five: they come as near 
Psittacodis magnus or sinensis (with which I for that reason compare them) as 
the three Eclecti do to each other:— 
1. Psittacus magnus et sinensis, Gm. ( viridis , Lath.; lateralis, Shaw; 
Mascarinus prasinus, Less.; Psittacodis magnus, Wagl.; Eclectus! polychlo- 
ros! Gy. ex Scopoli) PI. Enl. 514; Edw. B. t. 231; Lev. Perr. 1.132. 
Major: iliis rubris: margine alarum cyaneo: cauda apice subconcolori. 
2. Psittacodis intermedius, Bp. Mus. Lugd. 
Minor: iliis rubris: margine alarum rubro: cauda apice subconcolori. 
3. Psittacodis Westermanni, Bp. Zool. Soc. Amst. 
Minor: iliis concoloribus: margine alarum cceruleo: cauda apice subconcolori. 
Dedicated to the able and modest Director of the Zoological Society of Am¬ 
sterdam, where this new Parrot is living. 
t This new genus of mine, though composed of decided Trichoglossine Parrots, 
shows a strong affinity, not only to the Lorine but also to the Platycercine. It is 
composed in fact of 
1. Platycercus ater, Gr. {Psittacus novce guinece, Gm.; Ch.vovceguinece, Bp.); 
and of 
2. Eos scintillata, Gr. (Psittacus scintillatus, Temm.; Ch. scintillans. Bp.); 
to wdiich I have added a third new species, also from the Moluccas :— 
3. Chalcopsitta rubiginosa, Bp. Mus. Lugd. ex Ins. Barabav et Guebe. 
(Aves, PI. XYI.) 
E. purpureo-badia, capite obscuriore; subtus fasciolata, plumis singulis lunuld 
mediand et apicali nigricante: remigibus rectricibusque virescentibus cauda ; 
apicem versus gradatim lutescente. 
Rostrum rubrum : pedes nigri : irides albce. Magnitud. Turdi.
