The Irish Nahcralisl, 



January, 



Of the sgecies included in tlie above list the majority are 

 distributed fairly generalty throughout Ireland, but a 

 certain 'number have an Irish distribution which is de- 

 cidedly southern and eastern. A few species not in the list 

 may be added to this — what I may call — South-eastern 

 group, since, although they have not so far been recorded 

 for an}' of the six counties, they have only occurred in the 

 south and east of Ireland.

 eastern group : —
