150 The Irish Natm-alistx August, 



It is to be understood that these are onh' suggestions which 

 ma}' not meet with the approval of other biologists. There is 

 enough diversity at present existing in the various sub-divi- 

 sions of the countr}' which have been proposed, and my aim 

 has been not to add another group to these, but rather to 

 co-ordinate those already in existence, so that we should have 

 four provinces^ twelye sub-provinces, and forty counties and 

 vice-counties, all composed of the same units. But while 

 uniformity is desirable, unanimit}- amongst biologists is 

 equally so, and I should be glad to know the views of others 

 on this question.
