 M.R.C.S., AND THE REV. S. GRAHAM BRADE-BIRKS, M.SC. 



A. — A NEW LlTHOBIID. 



Irish material submitted to us for examination includes 

 a new variety of Monotarsohius duboscqiii (Brolemann)/ 

 which is characterized as follov»'s : — 



Monotarsohius duboscqui fosteri var. nov. 



The fifteenth (anal) pair of legs exhibits a diagnostic 

 character, each leg being terminated by a single claw. In 

 all essentials the other characters are those of the species. 

 Habitat.— Under a large stone about 50 yards from Lough 



Neagh shore, Raughlan, Co. Armagh. 

 Dedication. — We have pleasure in naming this variety in 



honour of our friend Mr. Nevin H. Foster, F.L.S., etc., 



of Hillsborough, Co. Down, who collected the type 



specimen, 27. vii. 1918. 

 Type. — Tube 1412, slide 1414, Brade-Birks collection. 



We have suspected the existence of this variety for 

 some time, and no doubt it will be found to be not uncommon 

 in the British Isles. 



B. — A Species new to Ireland. 



Mr. Foster recently submitted some material to us 

 which included a Julid previously unrecorded for Ireland, 

 viz. : — 



Cylindroiulus frisius (Verhoeff). 

 Syn. : lulus frisius Verhoeff, Berl. Ent. Zeitsch., 

 vol. 36 (1891) 1892, pp. 133 et seq. 



Externally this species is practically indistinguishable 

 from two other of its congeners knowTi from the British 

 Isles, C. hritannicus (Verhoeff) and C. parisiorum (Brole- 

 mann et Verhoeff). The gonopods, however, are fully
