I. Introduction. 



A short holiday in Derbyshire at the end of May and 

 beginning of June 1918 guve us an opportunity to collect 

 some centipedes and millipedes ; and we feel that the results 

 are of sufficient interest to warrant the publication of a 

 preliminary list for the county, so arranged as to make 

 mention of some of the work previously done by other 

 collectors as well as to,inc!ude our own 1918 records. Also, 

 in September 1916, we made one excursion from the Stafford- 

 shire side to the Derbyshire— Staffordshire boundary near 

 Beresford Hall; and, although there was some confusion in 

 our minds as to the exact position of the boundary, we have 

 incorporated some relevant results of that day's work in the 

 present paper, recording the specimens taken there as from 

 " near the R. Dove," because we are practically certain that 

 these are truly Derbyshire occurrences. If we are in error 

 about the county, the animals thus recorded were found close 

 to the boundary of the shires, but on the Staffordshire side. 

 Two species included under these circumstances in the present 

 list, viz. Polydesmus denticulatus and ScoliopUmes acuminatus, 

 are not otherwise known to us from Derbyshire. 



In several cases of material placed at our disposal by 

 Mr. Standen, Mill Dale (Staffordshire) is included in our 

 detailed records, because it is coupled as a collecting-ground 

 with Dove Dale (Derbyshire) ; but in no case does such an 

 occurrence stand alone as a county record. 



In the Diplopoda and Chilopoda (with which this paper 

 deals) we now know some thirty-one Derbyshire forms, and 

 these are enumerated below : — 



Diplopoda ( = Millipedes). 



1. Glomeris marginata (Villers). 



2. G. marginata perplexa, Latzel. 



8. lulus liyulifer, Latzel & Verhoeff.
