the Myriapoda of Ulster. 397 



The. nomenclature adopted in this paper differs considerably 

 (particularly in the Diplopoda) from that used in former 

 papers on the Irish Myriapods, and we must express our 

 thanks to Dr. Hilda K. and the Rev. S. Graham Brade-Birks, 

 who have kindly rendered much assistance in bringing it into 

 line with the conclusions of modern researtsh in the group. 

 References to the synonymy given in the subjoined list will 

 render comparison of this with former papers a matter of 

 little difficulty. 



Annotated List of the Myriapoda of Ulster. 



Class GHILOPODA (Centipedes). 



Order EPIMORPHA. 



Family Lithobidae. 



Lithobius forficatus (Linne). 



This species is common everywhere throughout the pro- 

 vince. Doubtless the same will prove true for Ireland, 

 although its presence in only 14 county divisions of the 40 

 has hitherto been recorded. 



Lithobius variegatus, Leach. 



This is the largest of the Irish centipedes, and, like the 

 preceding species, is common everywhere in Ulster. It still 

 awaits discovery in 17 county divisions of the other provinces. 



Lithobius melanops, Newport (-L. glabratus, C. L. Koch). 



Probably occurs throughout Ireland, having been recorded 

 from 17 county divisions in all the provinces. In Ulster it 

 has been found in Donegal E., Donegal W., Armagh, Down, 

 Antrim, and Londonderry. 



Lithobius agilis, C. L. Koch. 



The only Irish records for this species are from Coolmore, 

 Donegal E., and Acton Wood, Armagh. 



Lithobius borealis, Meinert. 



The inclusion of this species is somewhat doubtful, as in 

 the past it appears to have been confounded with the next 

 species. All the available Irish specimens on re-examination
