Notes on Myriapoda. 471 



included in the present studj- will be found in the twelfth 

 paper of tliis series (Brade-Birks, October 1918). 



Ill the second section of this paper other collectors^ names 

 are cited by initials ; where these latter are wanting, we were 

 the collectors ourselves. We have used as abbreviations 

 Lns. for Lincolnshire, Nk. for Norfolk, dist. for district, 

 M.-bj-T. for Martin-by-Tiniberlund, and syn. for synonym. 



Our best thanks are due to Mr. liagnall for his determina- 

 tion of Symphyla and other help, and also to the collectors of 

 material recorded in the present paper. The incorporation 

 of our own 1915 Lincolnshire specimens brings our early 

 inilebtedness to Dr. A. Randell Jackson of Chester pleasantly 

 to mind ; it was he who made an examination of those 

 specimens soon after they were collected.

Tl.is species was wrongly renamed /. IbjuUfer simply

 the ))roper specific name of this lulid."
