of the Genus Haplopelia. 3 



Taking the A section first, we have : 



1. Haplopelia larvata larvata. 



2. Haplopelia larvata bronzina. 



Taking the B section, we have : 



1. Haplopelia simplex simplex. 



2. Haplopelia simplex jacksoni. 



3. Haplopelia simplex inornata. 



4. Haplopelia simplex poensis. 



5. Haplopelia simplex plumbescens. 



6. Haplopelia simplex hypoleuca. 



7. Haplopelia forbesi. 



8. Haplopelia principalis . 



I consider that 2, 3, 4, 5, and 6 are subspecies of No. 1 

 (//. s. simplex). As regards Haplopelia forbesi, it will be 

 seen that I have here used binomial nomenclature, as I 

 believe that it will prove to be the hen of a bird very closely 

 allied to H. s. simplex, and will then become a subspecies of 

 the St. Thomas Island form. The bird will be fully discussed 

 in the following pages. 



No. 8, Haplopelia principalis, I consider to be a distinct 

 species, for reasons explained later.
