200 INHERITANCE, FERTILITY, AND SEX IN PIGEONS. 



The Indian species is held to be a subspecies of tlie Balkan or Asiatic species 

 {T. dccaoda), and for this subspecies Newman proposes to use Hodgson's name 

 "douraca," which was founded on a dove from Dhoiirakha.'"' Hodgson's name, 

 according to Salvadori, applies to all the ring-doves in Japan, China, Burma, India, 

 and the Balkans, except T. hiimilis and its Indian relative T. trancjueharicus. 



Newman states that the Burmese species ixanUwcychis) is easily distinguished 

 by its ' ' broad yellow bare rings round the eyes. ' ' He further claims, with Shelley , that 

 J". n'sorms (Barbary dove) is derived from the "rose-grej' turtle (\o\(^ [T .riseogriseus) 

 of North-eastern Africa." 



At this date (September 1906) it seems that the number of species of ring-doves 

 is not definitely settled. The following are fairly well determined : The common 

 ring-dove {St. risoria) goes (in a group? — Editor) with the African species St. 

 riseogriseus. The Balkan ring-dove (*S/. decaocta), Indian ring-dove (St. douraca), 

 Oriental ring-dove {St. torquatus) ,'^^ and Chinese- Japanese make one group. 



Thirteen species (besides risoria) are described by Salvadori (pp. 414-438). 

 The additional ones noted here indicate 17 species for the genus Streptopelia. There 

 are 14 species of gray to blond color, 1 species of white color, ^= 2 species of red or 

 ruddy color. (H 6) 



*" A place conjectured by Newman to be in Nepal, a country on the southern slope of the Himalaya system. 

 Hodgson's specimens were from Nepal, according to Salvadori. (See Hodgson in Gray's Zool. Misc. p. 85, 1844.) 



" At this later date the author seems definitely to agree to the separation of the Indian and Japanese forms. 

 Throughout this volume, however, the name douraca apphes to the Japanese ring-doves. — Editor. 



" This statement, too, indicates that Professor Whitman regarded .Si. alba as a good species. — EoiTon. (W 10
