In tlje section of the paper which deals will) detaih^l 

 records we liave introduced a few diagnostic points which 

 may be of value to other naturalists. 



Geological Considerations, etc. 



As far as our own 1918 collecting in the coujity is con- 

 cerned, we worked in two areas, both of them predominantly 

 limestone (Carboniferous Limestone) regions. The one was 

 the Buxton neiohbourhood, where Burbage was our centre, 

 and where all our collecting was on the limestone, and the 

 f)ther was moslly in the limestone tiiangle roughly formed by 

 Bakewell, Ashford, and Great Loni>stone ; this area is indi- 

 cated in the })resent paper as " Bakewell district," except 

 where more explicit details are given — as, for example, in 

 describing tiio occurrence of the new animals. One of us 

 (S. G. 15. -B.) acconi|)anied the veteran local naturalist and 

 antiquarian, Mr. \Villi\m Bonlsover, of Bidvewcll, on one 

 excursion to Manners Wood, wliich stands out on a sandstone 

 (Yoredale Series) ridge close to the town of Bakewell ; the 

 collecting done tliere is clearly indicated in the body of the 

 records, but it may be noted that, in one short visit, Lithohius 

 variegatus was taken there, although the writers did not meet 

 with it in either of the limestone areas, one near by, on the 

 occasion of their 1918 (May-June) collecting. The distri- 

 bution of this species, which is the only centipede on our 

 ]5ritish list which is unknown outside the British Isles, is 

 extremely interesting, and worthy of careful study, in which 

 natural factors, including altitude, vegetation, and geological 

 features should certainly be taken into account. 



It may be added that the junction between tiie Carboniferous 

 Limestone and the Yoredale lioeks in the neighbourhood of 

 tiie Derbysliire-Stafl'ordshire boundary, where we collected in 

 September lOlb", is near the county boundary in that area, 

 the Derbyshire side being tlie border ot an extensive 

 limestone region.

Din-ing our stay in the Bakewell district we made one 

 excursion through Munsal Dale to Cressbrook with Mr. J. K. 

 Widdowson to visit a cave in the limestone at Burymewick, 

 but, after all, we were not successful in Hntiing any 

 niyriapods there. Some good results are to be expected from
