Rev. Brade-Birks consider it probable that the forma typica

Brachydesmus superus mosellanus, Verhoeff". 



Verhoeff has shown that this differs from typical B. superus, 

 and specimens taken near Stewartstown, Tyrone ; Bally- 

 magee, Down; and Gawley's Gate (Lough Neagh), Antrim,

Polydesmus gallicus, Latzel. 



This species has been found at Virginia, Cavan ; Armagh ;

Polydesmus denticulatus, C. L. Koch. 



Apparently not common here, but we have records for this 

 species from Hillsborough, Down ; Murlough Bay, Antrim ;

Polydesmus edentulus, C. L. Koch. 



The only Irish records for this species are from Poyntzpass, 

 Armagh; and Belfast, Antrim.

 Cavan ; Hillsborough and Ballymagee, Down ; Carr's Glen, 

 Murlough Bay, and Torr Head, Antrim ; and Benevenagh,
