absent from the north-west. Dr. Scharff' has ah'eady called attention to the 

 absence of this species from the central bogs of Ireland ;^ and Dr. Chilton also 

 notes its absence from a collection made at various times in county Galway 

 by Professor D'Arcy Thompson, which collection is now in University College, 

 Dundee.^ Whether these boggy regions form a barrier which cuts it off 

 from the north-west we cannot say ; but the fact remains that no specimen 

 has been found north of a line drawn from Larne to Galway. A. vulgare 

 is a common species in Munster and Leinster, with the exception of the 

 counties of Kerry and Longford. From Connaught it has been recorded 

 only from two localities in S.E. Galway ; whilst in Ulster it is plentiful 

 on the limestone formation in Armagh, not uncommon in a limited area in 

 Down (in the neighbourhood of Downpatriek), and has been found in one or 

 two spots in the southern end of Antrim, the remaining counties m the province 

 being apparently devoid of this species.
