60 Prof, Giaciuto Martorelli on the 



rectrices." From the series now in tlie Tring Museum^ which 

 embraces examples of all the species of the genus, I am able 

 to state that there is no constant difference in size between 

 P. brehmi typica and P. brehmi pallida, and that the sub- 

 metallic bluish-green gloss on the lower surface of the 

 rectrices is merely an individual character, obvious in some, 

 quite absent in other specimens. I believe it is visible 

 in quite freshly-moulted individuals. On the other hand 

 there are sufficient differences in other respects, as explained 

 by me in 'Novitates Zoologicse,' vol. iii. pp. 18 and 255. 

 The genus Psittacella thus constitutes itself as follows : — 



1. Psittacella brehmi (Rosenb.), occurring in two forms: 



a. P. brehmi typica, Arfak Mountains ; 



b. P. brehmi pallida, Owen Stanley Mountains. 



2. P. picta, Hothsch., Mt. Victoria, Owen Stanley Moun- 

 tains, 



3. P. modesta (Schleg.), Arfak Mountains. 



4. P. madaraszi, A, B, Meyer, Owen Stanley Mountains. 

 Hardly more than half of the great island of New Guinea 



having been explored, and that only, for the most part, 

 insufficiently, we shall not be surprised if more new forms 

 belonging to this genus are discovered. 



VI. — On the Variations of a Lory (Eos fuscata) as exhibited 

 by Specimens in the Turati Collection. By Prof. Giacinto 

 Martorelli (Civic Museum of Milan). 



The specimens of Eos fuscata, Blytb, of which I give the 

 descriptions, are fourteen in number, and show every stage 

 of development, from the nestling to the adult bird, with 

 striking gradations between the yellow and the red coloration, 

 which appear to be totally independent of age, sex, and 

 geographical range. The red colour seems to replace the 

 yellow only as an ordinary intensification of the yellow 

 pigment, which becomes more or less red in various indi- 

 viduals, independently of their age.
