the Myriapoda of Ulster. 401 



has been found in Cavan, Monaghan, Armagh, Down, and 

 Antrim. 



Class DIPLO POD A (Millepedes). 



Order PSELAPHOGNATHA. 



Family Polyxenidae. 



Polyxenus lagurus (Linne). 



The only Ulster record for this species is by the late H. L. 

 Orr, who found it under the bark of a tree at Old Forge, 

 Dunmurry, Co. Antrim. Elsewhere in Ireland it has been 

 found in the counties of Dublin and Wicklow. In the latter 

 county the writer found four specimens under a stone on 

 Bray Head. 



Order CHILOGNATHA. 



Family Glomeridae. 



Glomeris marginata (Villers). 



With the exception of Cavan this species has been taken 

 in all the Ulster county divisions, where it proves to be 

 common, as doubtless obtains throughout Ireland, though it 

 is as yet unrecorded from eighteen county divisions. Being 

 able to roll itself up into a perfect ball, it is known as the 

 pill-millepede. 



Family Iulidae. 

 lulus ligulifer, Latzel ( = /. scandinavicus, Latzel). 



This species is apparently not common. In Ulster it has 

 been recorded from Cavan ; Dunfanaghy, Donegal W. ; 

 Armagh ; Ballynahinch, Ballymagee, and Hillsborough, 

 Down ; several stations round the coast from Cushendall 

 to Whitepark Bay, Antrim ; and Banagher and Dungiven, 

 Londonderry. Outside Ulster the only Irish records are 

 from Wicklow and Leitrim. 



lulus (Ophiiulus) fallax, Meinert. 



This is a common species occurring in numerous localities 

 in all the Ulster counties except Cavan, where doubtless it 

 will eventually be found.
