1 14 Ihe Irish Naturaluf. June, 



Geophilus truncorum, Meinert. 



This is one of the smallest of the Geophilid centipedes 

 and may be easily identified by the presence of three strong 

 parallel furrows on the ventral plates of the anterior 

 segments. 



The single specimen was found at Ballycastle, Co. Antrim, 

 in 1897. 



Craspedosoma Rawlinsii, Leach. 



This specimen was taken at Downpatrick in 1895, 

 probably by Mr. R. Welch, who tells me he was collecting 

 there about that time. 



It belongs to the family Chordeumidae, the only other 

 member of which found in Ireland is Atractso7na polydes- 

 nioides, Leach. From this species it may be distinguished 

 by the much feebler development of the keels on the 

 see:ments, by the distribution of the bristles on the dorsal 

 surface and by the structure of the copulatory feet of the 

 male. It may be separated at once from the Polydesmidae, 

 to which it bears a superficial resemblance, by the possession 

 of thirty instead of twenty body segments, and by the 

 presence of eyes. 



Since Leach's time the species Rawlinsii has been sub- 

 divided. The present specimen appears to belong to the 

 sub-species genuinum, Verhoeff. 



In addition to these two species, I have identified the 

 following three new to Ireland from the unnamed material 

 in the Museum. 



SCHENDYLA NEMORENSIS, Koch. 



This species is represented by two specimens, one from 

 Glenveagh, Co. Donegal (July, 1910, Mr. R. Welch), the 

 other from Lambay (1906, Prof. Carpenter). 



It is a small and very slender centipede of the Geophilid 

 group. It may be distinguished from any of the other 

 British centipedes, except 5. submarina, Grube, by the 

 form of the last pair of legs, and the two large coxal pores 

 which are partly covered by the terminal ventral plate.
