200 INHERITANCE, FERTILITY, AND SEX IN PIGEONS. 



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

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

 "douraca," which was founded on a dove from Dhourakha. 40 Hodgson's name, 

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

 and the Balkans, except T. humilis and its Indian relative T. tranguebaricus. 



Newman states that the Burmese species (xanthocydus) is easily distinguished 

 by its " broad yellow bare rings round the eyes." He furtherclaims, with Shelley, that 

 T. risorius (Barbary dove) is derived from the "rose-grey turtle dove (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 (St. decaocta), Indian ring-dove (St. douraca), 

 Oriental ring-dove (St. torquatus),* 1 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, 42 2 species of red or 

 ruddy color. (H 6) 



40 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.) 



41 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 applies to the Japanese ring-doves. EDITOR. 



42 This statement, too, indicates that Professor Whitman regarded St. alba as a good species. EDITOR. (W 10
