184 Mr. J. A. Harvie Brown on the 



south of Perm, and on the Kama river, and will prove useful 

 in studying the distribution of species in the east of Russia in 

 Europe*. 



The following Tables are given to show : — 1st, the faunas, 

 as far as at present recorded, of the three districts of the 

 Southern Division ; and, 2nd, that of the Northern Divi- 

 sion as compared with that of the Southern Division. This 

 latter must be considered in its present state as somewhat arbi- 

 trary, andcannot be held to clearly represent the faunal relations 

 of the two Divisions : nor can we expect to institute an exact 

 and faithful comparison until our knowledge of the faunas of 

 the terrcB incognitce of these Divisions becomes more com- 

 plete. 



In Table I., as with the Northern Division, I have given 

 a place to every record, whether fully authentic or not ,• and 

 later I have treated of the doubtful records and rare occur- 

 rences in notes^ to which references are given in the Tables. 

 Under these notes, also, will be found references to Table II. 



In Table II., in cases where I have considered the data 

 insufficient to generalize from, as regards the ascertained faunal 

 value of the species throughout the Divisions, I have, in some 

 cases, only entered the symbol for simple " presence," and in 

 other cases, where required for further elucidation, the addi- 

 tional symbols for "locally" (0) and " generally distributed " 

 ( o ) . Further exploration in the unworked parts of the Divi- 

 sions will help us to arrive at more accurate and minute re- 

 gistration in this comparison than is at present attainable. 



The Seasonal Distribution in Table II. is shown as far as 

 I have data. Where I have no data, or where doubt occurs, 

 I omit it [vide Symbols). 



* Besides the above, the following papers should be mentioued as 



bearing upon oui- subject. Where necessary I have referred to these in 



footnotes.
