396 Mr. N. H. Foster on 



Practically all the specimens included in this list have heen 

 collected by a few members of the Belfast Naturalists' Field 

 Club, and from time to time have been identified by Dr. and 

 the Rev. S. Graham Brade-Birks, Dr. H. W. Brolemann, 

 Dr. A. Randell Jackson, the Rev. W. F. Johnson, Messrs. 

 R. I. Pocock and R. S. Bagnall, and the late Lieut. C. M. 

 Selbie ; and to them thanks are due for the examination of 

 the collections sent them. Further, we tender our thanks to 

 Dr. R. F. Scharff, who has kindly permitted the extraction 

 of Selbie's unpublished notes preserved in the National 

 Museum, Dublin. 



Exclusive of one exotic species (see p. 406) taken in a 

 warm greenhouse, 55 species of Myriapods have been found 

 in Ireland, and of these 52 have been identified from the 

 Province of Ulster. It may be, as will be mentioned in the 

 following notes, that doubt exists as to the validity of some 

 of these species being included in the Irish list, but pending 

 future investigation it has been considered advisable to cite 

 them. 



The subjoined table gives the number of species recorded 

 from each of our county divisions : — 



Table showing number of Species of Myriapoda recorded from 

 each Ulster County Division. 



Cavan 14 species. Tyrone 18 species,. 



Mouaghan .... 16 „ Armagh 33 „ 



Fermanagh ..11 „ Down 39 „ 



Donegal East . 13 „ Antrim 41 „ 



Donegal West . 18 „ Londonderry . . 22 „ 



As will be observed, the records from some of the county 

 divisions are somewhat meagre, and in them doubtless many 

 species await discovery. But as it appears unlikely that 

 exhaustive collections will be undertaken in the near future, 

 it has been considered advisable to publish the present list as 

 a basis for future workers. It will be noted that the largest 

 of the Ulster counties — Donegal — has been divided into East 

 and West divisions in accordance with Praeger's scheme *. 

 These two divisions are separated by a line running N.E. 

 and S.W. from the head of Donegal Bay to the head of 

 Lough Swilly, dividing the Baronies of Bannagh, Bo} T lagh, 

 and Kilmacrenan from Tirhugh, Raphoe, and Inishowen.
