Last year Dr. A. Randell Jackson recorded f the finding by 

 one of ns \ at VVinkhill, near Leek, Staffs, of Cylindroiulus 

 {Leucoiulus) nitidus (Verhoeff). This seems to Iiave been 

 the tirst record of the occurrence of tliis species in Britain, 

 and the following notes are based primarily u})on our study 

 of material from the locality named in the light of the original 

 paper § in which Dr. C. W. Verhoeff describes Julus nitidus. 

 Of this description we have made the fullest use, and we here 

 ex))res3 our indebtedness. 



Our specimens were first examined by D''. Jackson, and 

 then sent to Monsieur le Docteur Henry VV. Biolemann of 

 Pau, who, with iiis usual kindness, dissected one of the males, 

 and identified it as the Julus nitidus described by Verhoeff. 



1. Occurrence and Habitat. 



Cylindroiulus nitidus was taken in September 1915 at 

 Wiiikhill, Staffs, by one of the writers (H. K. B.) ; three 

 males and two immature specimens were found together under 

 a stone on the grassy sides of the road leading from the 

 station to the village; no adult females were then taken. 

 Ill September 1916, when we had already made some study 

 of the limited material then at our disposal, we took many 

 specimens of both sexes in the same immediate neigiibourhood. 

 In the field C. nitidus resen.bles C. silvariun (Meinert) very 

 closely except in habitat. Verhoeff states (/oc. cit.) that he 

 Lad noticed this animal only in woods or on heights. He 

 records it in the Khine and Most lie districts: at Meibthal, 

 near Bonn, in a wood under leaves ; at Ippendort'er Hohe, 

 near Bonn, at the edge of a wood under stones ; at Cociiem, 

 in woods and at Siebengebirge, Petersberg, in woods under 

 stones. There are some trees in the neighbourhood of the 

 ground where the English specimens were collected at 

 Winkhill; but the very limited area of its occurrence is not 

 in close connection witii woods, the district being hilly and
