II. The south-eastern district, comprising Chu, Talhis, 

 Djumgal, Susamir, the lower Narin, Son-kul, and Chatir-kvil. 



III. The north-western district, comprising Karatau, the 

 western Thian-shan mountains, the upper portions of the 

 rivers Aris, Keless, Chirchick, and their tributaries, the lower 

 Syr-Darja, from the sources of the Aris to Lake Aral and the 

 delta of the Syr-Darja. 



IV. The south-western district, comprising the Chodjent 

 district, the entire Zarevshan valley from the summit of the 

 Zarevshan mountains, the Syr-Darja river and the steppes 

 between the latter river and the Kisil-eum. 



The second section comprises the vertical range, showing 

 the altitude at which the various species are met with. This 

 is divided into five districts, viz. : — 



1. From 600 to 1000 feet above the sea-level, comprising 

 the salt plains. 



2. The cultivated districts, grassy steppes, and gardens to 

 3000 or 4000 feet altitude. 



3. The larch-Avoods, apple- and ash-groves of the Karatau 

 and the lower Thian-shan mountains to an altitude of 4500 

 feet^ or even in some places to 7000 or 8000 feet, or, say, an 

 average altitude of about 6000 feet. 



4. The fir and birch districts of the Thian-shan to an alti- 

 tude of from 8500 to 10,500 feet, or to the juniper district. 



5. The district covered with alpine grasses, below the line 

 of eternal snow, at from 10,500 to 14,000 feet altitude. 



Being unable to reproduce these tables, I have defined the 

 range by referring to the districts above given under each 

 species, which will, I trusty answer the purpose. 



In cases where I can with a fair degree of certainty iden- 

 tify the species described, I have added short notes of my own, 

 but have in every case deemed it best to copy Mr. Severtzoff^s 

 description where he has described a species as new.
