THE BIRDS OF MONGOLIA ETC. 381 



189. TURTUR RUPICOLUS, Pail. 

 Temminck, PL Col. pi. 550. 



We came across this species in the Muni-ul mountains and in the 

 Hoang-ho Yalley. Towards the end of August we took some unfledged 

 young (alw^ays two in a nest)^ and on one occasion even two eggs. 



It does not occur in Kan-su, Koko-nor, or Halha. 



In Ussuri coimtry its migration takes place late in March or early in 

 April; and it breeds there in limited numbers in the small woods near 

 rivers. 



190. TuRTUR viTTicoLLis, Tcmm. Gorlitza smejushtshayasia. 



Turtur duraca, Schlegel, Mus. P.-B. Columbce, p. 123. 



We met with it only in the park of the Ala-shan, chiefly in the town of 

 Din-juan-in, and in Kan~su. 



Our Mongohan specimens are a little larger than the measurements 

 mentioned by Schlegel; and the same has been noticed in the specimens 

 which were brought by Schrenck from the Amur. 



Measurements of the male— length 13'-14'-3, width 19", wing T-T'A, 

 tail 5"-8-6^'-45, tarsus 0''-84-0"'85, gape 0"-88-0"-92. 



191. Turtur humilis, Temm. 



Temminckj Les Pigeons^ ii. pi. vii. 



We only once met with these birds, about the middle of June, in the 

 park of the Ala-shan. It was a pair ; and apparently they were breeding 

 there.
