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 Los 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 
Fringillide, and amongst the Parrots Psittacodis* and Eelectus 
confounded together by the same process! 
The genus Los is intermediate between the two subfamilies Trc- 
choglossine and Loriine. 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 t, 
* Since I speak of Psittacodis (the only green Genus of Lorine Parrots, which 
forms the same beautiful passage from Loriine to Psittacine that Eos does from 
Trichoglossine to Loriine), 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 Eelecti do to each other :-— 
1. Psirracus MAGNUS et sINENSIS, Gm. (viridis, Lath.; lateralis, Shaw; 
Mascarinus prasinus, Less.; Psittacodis magnus, Wagl.; Eclectus! polychlo- 
ros! Gr. ex Scopoli) Pl. Enl. 514; Edw. B. t. 231; Lev. Perr. t. 132. 
Major: iliis rubris: margine alarum cyanea: cauda apice subconcolori. 
2. PsiTracoDIS INTERMEDIUS, Bp. Mus. Lugd. 
Minor : iliis rubris: margine alarum rubro: cauda apice subconcolori. 
3. Psirracopis WESTERMANNI, Bp. Zool. Soc. Amst. 
Minor : iliis concoloribus: margine alarum ceruleo: cauda apice subconcolori. 
Dedicated to the able and modest Director of the Zoological Society of Am- 
sterdam, where this new Parrot is living. 
+ This new genus of mine, though composed of decided Trrichoglossine Parrots, 
shows a strong affinity, not only to the Lorine but also to the Platycercine. It is 
composed in fact of 
1. PLarycercus ATER, Gr. (Psittacus nove guinee, Gm.; Ch. nove guinee, Bp.); 
and of 
2. Eos scintILiata, Gr. (Psittacus scintillatus, Temm.; Ch. scintillans, Bp.); 
to which I have added a third new species, also from the Moluccas :— 
3. CHALCOPSITTA RUBIGINOSA, Bp. Mus. Lugd. ex Ins. Barabay et Guebe. 
(Aves, Pl. XVI.) 
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 alba. Magnitud. Turdi.
