464 MR. E, p. UVAROV ON THE GEOGIIAPIIICAL DISTRIBUTION 



Kaklietian district is connected with the southern part, the district 

 thus ranging all over the northern slopes of Minor Caucasus 

 as far eastwards as Karabagh, where its fauna,, becoming gradually 

 poorer, comes in contact with the fauna of Aderbaidzhan. 



10. The Talysh district (T.). 



The fact that we only know 45 species of Orthoptera (3M + 

 24A + 8L + 10G) from this district is certainly due not to its 

 poverty but to incomplete investigations. 



As regards the composition of the Talysh fauna, it gives the 

 impression of bearing resemblance to that of tlie adjacent Caspian 

 Transcaucasia, being distinguished from it by the presence of 

 five forms only, as follows : 



Acrida turrita tuvrita. 

 Parapleurus alliaceus. 

 Stenobotlivus macrocerus. 

 Epacromia strepens strepens. 

 Platj'cleis capitata. 



The latter of these is an endemic species, while the presence of 

 the four remaining ones indicates the close affinity of the Talysh 

 fauna to that of the Balkano- Anatolian province. The most 

 remarkable fact is that Acrida turrita and Epacromia strejjens 

 are represented in the Talysh district, not by the desert sub- 

 species inhabiting the Caspian Transcaucasia, and Aderbaidzhan, 

 but by tlie same races thnt a,re met with in the districts belong- 

 ing to the Balkano-Anatolian piovince, the range of these sub- 

 species being discontinuous The affinity of the Talysh fauna 

 with the Balkano-Aiiatolian one is even more defined by the fact 

 that its difieience from the latter can be based upon a single 

 subspecies (leaving the endemic FlatycJeis capitata nsu]e) — Decticus 

 verrucivorus boldi/revi, Avhich no doubt ca,me here recently fiom 

 the neighbouring deserts. The influence of the Eremian fauna on 

 the fauna of Talysli is, generally speaking, very well marked, 

 resulting in the presence of such forms as Thisoecetrus dorsatus, 

 Platycleis escalerai, LiognjUus himaculat^is, etc., but it should be 

 regarded as of secondary natvire. The immediate connection of 

 the Talysh with the other districts of the Balkano-Anatolian 

 province is now absent, but it no doubt existed formerly ; I think 

 it should be looked for in the south-eastern (Karabaghian) branch 

 of the Somkheto-Kakhetian district which formerly used to 

 reach the Talysh. 



In the district of Talysh I include only the lather narrow strip 

 along the southern shore of the Caspian Sea, the southern bound- 

 ary of this district being the upper limit of the forests on the 

 northern slopes of the Talysh mountains. The north-western 

 boundary delimitating Talysh from the adjoining deserts of 

 Caspian Transcaucasia is rather indefinite ; the north-eastern one 

 is completely unknown.
