310 The Irish Naturalist. 



may in reality be so easily attained, it is to be hoped that 

 naturalists resident in Ireland will begin to pay some attention 

 to these interesting but much neglected animals. 



LIST OF THE SPECIES. 

 CHILOPODA. 



(CENTIPEDES.) 



FAMILY LITHOBIID^. 



Lithobius forficatus (Linn). 



Poulaphuca, Co. Wicklow ; Dingle ; Glengariff ; Bere Island 

 (Bantry Bay). 



Common throughout the whole of N. Europe ; occurs also in 

 N. America. 



L. variegatus, Leach. 



Dublin mountains ; Dalkey Island ; Kilruddery, Glen of the 

 Downs (Co. Wicklow) ; Enniskerry (Co. Wicklow) ; Kylemore 

 (Connemara) ; Killarne}^; Castletown Berehaven ; Glengariff. 



Abundantly distributed throughout the British isles, and occurs 

 also in Jersey. It has not yet, however, been recorded from any 

 part of the continent of Europe. 



This is a handsome species, rivalling L. forficatus in size, but 

 readily to be distinguished from it by its variegated yellow and 

 blue colouring, larger head, longer and thinner anal legs, etc. 

 L. forficatus is a uniform chestnut. 



In the south of England it is a noticeable fact in connection with 

 these two species, that L. forficatzts is found most abundantly under 

 bricks and planks, in or near yards, outhouses, etc. L. varicgatus, on 

 the contrar}^ is found under stones and tree-trunks in woods, or 

 the open country. 



These facts in distribution suggest that L. forficatus has been in- 

 troduced into our country later than Z. vai-iegatus. 

 L. melanops, Newp. [^^labratus, C. Koch et alii). 



Poulaphuca, Co. Wicklow ; Castletown Berehaven ; Derrynane. 



This species somewhat resembles Z. rariegatzis in colouring. It 

 is, however, considerably smaller, and has only four instead of 

 ten maxillary teeth. 



L. microps, Meinert. 



Glengariff. 



This species is abundant in the S. of England, and, at least, in 

 the northern parts of Europe. It is one of the smallest of the 

 genus, and may be readily recognised by the fewness of the ocelli, 

 and by the very small number of spines upon the anal legs. 



FAMILY SCOLOPENDRID^. 



Ci*yptops hortensis, Leach. 

 Dublin. 

 Common all over Europe. 



FAMILY GEOPHILID^. 



Ceophilus flavus, De Geer {hmgicomis, Leach). 



Dingle ; Glengariff; Kylemore (Connemara). 



Common all over Europe. Easily recognizable from the other 

 British vSpecies by its long cylindrical antennal segments.
