180 THE BIRDS OF MONGOLIA ETC. 



70. Cyanecula c^rulecula, Pall. Varakusha. 



Does not appear to breed in Mongolia, and was found by us only during 

 migration, about the end of August and beginning of May, in the northern 

 bend of the Hoang-ho. The birds were flying about singly in the bushes 

 and groves of trees. About August w^e met with some migrating specimens 

 in Central Gobi. In Kan-su we did not meet with any. 



71. Calliope kamtschatkensis, Gmel. Solovey crasnosheyka. 



Calliope kamtschatkensis, Gould^ Birds of Europe^ pi. cxviii. 



During the spring migration we observed a single specimen in the 

 Hara-narin-ul mountains, but found it tolerably abundant in the wooded 

 parts of Kan-su, where it principally keeps to the thickets close to 

 rivers and brooks, and cleverly climbs about in the trees, like our European 

 Bluethroat, which it very much resembles in its habits. 



The birds arrived at Kan-su about the commencement of May, and 

 occurred singly or in small flocks (five to eight individuals). By the middle 

 of May they had selected their localities ; and from that time the splendid 

 singing of this bird could be heard in all the mountain-valleys, especially 

 in the morning. It breeds but sparingly about Hank a, but is very numerous 

 there during migration. 



72. Calliope TSCHEBAiEwi,n.sp. Solovey Chehaew a, (PlateLIV. i.fig.l.) 



C. pectorali similis^ sed area gulari rubra majore^ et mystacibus albis ut in C. kamtschatkensi. 



The more exact particulars as to the differences between this and the 

 closely allied C pectoralis are the following : — 



{a) Crown, back, and rump dark olive-colour ; whilst in C pectoralis 

 they are dark grey. 



(6) The red band on the throat is much wider.
