Supplemental List. — Mainland. 



Although only a few of the species from Clare Island, enumerated above 

 were found on the adjacent mainland, there can be no reasonable doubt that 

 they belong to the fauna of the district. Seven species of Collembola, how- 

 ever, not found on Clare Island, occurred on the mainland or Achill; and it 

 seems convenient to enumerate these in a separate list. 



PODURIDAE. 



Lipura ambulans (Linne). 



Belclare, Westport (J.N. H., July, 1911). 



This species is common in soil and under stones throughout Ireland and 

 Great Britain. Abroad it is found both in Europe and North America, but 

 it does not extend into arctic or subarctic regions. Linnaniemi states (1912 

 p. 91), for example, that it is very scarce in Finland, and appears to be 

 restricted to the southern districts of the country. 



ENTOMOBRYIDAE. 



Anurophorus laricis Nicolet. 



Achill, on trees in wood near the Sound (July, 1911). 

 This is another widespread Irish and British species, inhabiting also North 

 America, Europe, and Siberia. 



Entomobrya nivalis (Linne). 

 Degecria annulata Lubbock (Monograph, 1873). 

 Belclare, Westport (J. N. II., July, 1911). 



This is another widespread springtail with Britannic and foreign distribution 

 like those of the last-named species. 



Entomobrya multifasciata (Tullberg). 

 Degecria nivalis Lubbock (Monograph, 1873). 

 Croaghpatrick (J.N. H., June, 1909). 



The occurrence of this species in our islands is interesting, as it may 

 usually be found on the tops of mountains (I have taken it on the Macgilly- 

 cuddy's Beeks and the Mournes), and also in gardens and greenhouses. As 

 yet it does not seem to be certainly known outside northern and central 

 Europe. 



Lepidocyrtus lanuginosus (Gmelin). 



Belclare and Knappagh, Westport (J. N. H., July and August, 1911). 

 A widespread species in Ireland and Great Britain, extending throughout 

 Europe into northern Siberia, Spitsbergen, and North America.
