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

 one of us \ at Winkliill, near Leek, Staffs, of CylinS'ohdus 

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

 the first record of the occurrence of this species in Britain, 

 and the following notes are based primarily upon our study 

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

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

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

 exj)ress our indebtedness. 



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

 then sent to Monsieur le Docteur Henry W. Brolemann of 

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

 and identified it as the Julus nitidus described by Verhoeff. 



1. OCCUEEENCE AND HaBITAT. 



Cylindroiulus nitidus was taken in September 1915 at 

 "Winkliill, 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. 

 In 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 neighbourhood. 

 In the field C. nitidus resembles C silvarum (Meineit) very 

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

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

 records it in the Khine and Mostlle districts : at Melbthal, 

 near Bonn, in a wood under leaves ; at Ippendorfer Hohe, 

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

 in woods and at Siebengebirge, Petersberg, in woods under 

 stones. There are some trees in the neigiibourhood of the 

 ground where the English specimens were collected at 

 "VVinkhill; but the very limited area of its occurrence is not 

 in close connection with woods, the district being hilly and
