generally darker tlirougliout tlian P. e. erithacus, but it must 

 be remembered that birds from tlie mainland often exhibit 

 considerable variation in this respect. It will probably be 

 found that there are several races of this Parrot in Africa, 

 and, indeed, Dr. Hartert has already separated the bird 

 from the Congo which he has named P. e. megarhynchus 

 (vide Kat. Senckenb. Mus. 1891, p. 157), on account of 

 its large bill. 



P. erithacus timneh Fraser, from Sierra Leone and Liberia, 

 seems to be a perfectly distinct form, but I have not 

 sufficient material to enable me to review the geographical 

 races of the Grey Parrot which quite possibly exist.

 from Prince's Island.

Keulemans occasionally found small flocks of these parrots 

 in the most deserted parts of the island, but says that they 

 are rare and very shy. Dohrn, in his paper, notes that the 

 species is said to occur on the island, but that he never 

 observed it himself. This is the common " Love-bird " of 

 the West Coast, and has a wide distribution in Tropical 

 Africa. It is an inhabitant of both Fernando Po and 

 St. Thomas' in the Gulf of Guinea. 



It would appear doubtful whether it is still found on 

 Prince's Island as none of the recent collectors have obtained 

 it. As it is a very favourite cage bird it is, doubtless, often 

 imported.

Alexander evidently did not meet with the Tropic-bird on 

 Prince's Island. Keulemans notes that it is " sometimes
