followed the 40 county divisions as scheduled by E. LI. Praeger.' In this 

 scheme some of the larger Irish counties have been divided, so as to render 

 each of the divisions more nearly approaching to an approximate size. Each 

 county division is designated by a number commencing with Kerry South, 

 No. 1, in the south-west, and ending with Londonderry, No. 40, in the north. 

 A glance at the map (p. 167) shows how these numbers are arranged, 

 and the names of the county divisions to which these numbers are attached. 



As the publication of a separate map of the above type for each species 

 dealt with would entail considerable expense, we have adopted the system 

 detailed by E. LI, Praeger.* By this method no outlines are given, but the 

 reference numbers of the county divisions are placed as nearly as possible 

 relatively to each other as they would appear on the map of Ireland. All 

 the numbers of the county divisions are inserted in each sketch-map; the 

 numbers printed in heavier type denoting that, in the county divisions so 

 printed, the species in connexion with which the sketch-map is given has 

 been recorded.
