 I shall not therefore discuss the matter further.

C a. sjostedti is distinguished from typical C. arquatrix hy 

 its smaller size and by having the crown of the head uniform 

 grey. Moreover, it is much more closely spotted on the 

 under parts.

Since wiiting on the birds of Prince's Island, St. Thomas, 

 and Anuobon, I have spent a considerable time in working 

 at the members of the genus Haplopelia. I have had to 

 practically monograph the entire group, and the results 

 "will be published in a separate paper in the next number of 

 the ' Ibis.^ I have there gone very fully into the question 

 of the validity of each species, and shall not therefore touch 

 on the matter here. 



As the male has never apparently been described I append 

 the following : — 



Adult male. Forehead white, becoming greyer towards 

 the crown. Occiput darker grey than the crown, and 

 viewed in certain lights appearing brilliant green and in 

 others shining amethystine, which colour extends on to the 

 hind-neck, sides of the neck, and upper part of the mantle.
