472 Dr. & the Rev. S. Graham Brade-Birks— 



female 14-16 mm. long, 1*2-1*3 mm. broad ; male 10-13 mm. 

 long. 



This species is often found on the coast of England, but 

 may also be met with well inland. Tue gonopods of the 

 male are diagnostic. 



On the shore under wood (including male dissected for con- 

 firmation) and in farm precincts, inland (male also dissected), 

 Heacham, Nk. ; under a stone (male again dissected) near 

 Sandringham, Nk. Material probably referable to the species 

 but not confirmed by dissection, as follows : — in ants' nest, 

 inland, Heacham, Nk. ; outskirts of wood between North 

 Wooton station and Castle Rising, Nk. 



Cylindroiulus londinensis, var. Jinitimus, Ribaut. 



Dimensions and other characters are mentioned in the 

 thirteenth paper of this series (Brade-Birks, Sept. and Oct. 

 1918). 



Under stones by roadside, Castle Rising, Nk. 



Cylindroiulus londinensis, var. teutonicus (Pocock). 



Dimensions and other characters are again indicated in our 

 thiiteenth paper (Brade-Birks, Sept. and Oct. 1918). 

 Under stones by roadside, Castle Rising, Nk. 



Cylindroiulus punctatus (Leach). 

 Sjn. C. silvarum (Meinert). 



Harlaxton, Lns., J. C. V.-S. ; male and female, M.-by-T. 

 dist., Lns. ; between bark and trunk of felled timber (male 

 disseeted for confirmation), Heacham, Nk.; outskirts of wood 

 between North Wooton station and Castle Rising, Nk. 



Cylindroiulus (Leucoiulus) nitidus (Verhoeff). 



This species is dealt with at some length in our fifth paper 

 (Brade-Birks, May 1917). 



Males are necessary for definite diagnosis. Mr. Bagnall 

 refers the following example to the species : one female, 

 Harlaxton, Lns., J. C. V.-S. 



At Heacham, Nk., we took several females, which are, 

 perhaps, referable to this species. 



Schizoplryllum sabulosum (Linne*).
