abundant, three yield both species in approximately equal numbers. 

 An interesting feature is the prevalence of bandless H. nemoralis : 

 typical " limestone " and " non-limestone " series may be distinguished 

 at a glance. The width and mtensity of the bands in H. hortensis, 

 and the tendency of the bands to coalescence, are all, generally 

 speaking, less marked in limestone localities than in other stations, 

 though actually bandless shells are rather less frequent. 

 Non-Limestone Localities. 



1. P>oghall. H. nemoralis alone found; vars. libellula 00300, 

 libellula-fascialba 00300, rubella 00000, 1(2345); rubella-fascialba 

 00300. 



2. Oakamoor. 



(a). On the railway embankment north of the tunnel (var. 

 rubella 00300) and near the cricket field (vars. libellula-fascialba 

 00300, rubella-fascialba 00300), a few specimens of H. nemoralis have 

 been found — probably introduced. No H. hortensis. 



(b). On the Star Road. H. nemoralis alone ; vars. libellula 

 00000, 00300, (12)3(45); rubella 00300; rubella-fascialba 00300, and 

 roseozonata-roseolabiata with very pale translucent bands, 12345, 

 00300. 



(c). Near the Vicarage, Farley Road. H. nemoralis only ; vars. 

 libellula 00000, 00300; libellula-albolabiata 00000; rubella 00000, 

 12345, 123(45), 00300; rubella-umbilicata 00300. 



(d). Above the New Lodge, Farley Road. H. hortensis 

 abundant ; H. nemoralis much less frequent, not more than one to 

 eight. Of the former the band varieties 12345, (12345), (i23)(45), 

 (123)45, (12)3(45), 123(45), 1(23)45, i(23)(45) have been recorded, 

 and of H. jiemoralis the var. rubella 00000, 00300 only. 



3. Along the roadside from Farley, past Alton Park, H. horlensts 

 occurs sparingly — vars. 12345, (12345), (123)45, ^"^ 00000 have 

 been seen — but II. nemoralis has not been found. 



4. Near Wootton Lodge two specimens of H. nemoralis have been 

 seen — var. rubella 00000, 00300 — but no H. hortensis. 



5. EUastone. 



(a). On a steep roadside not far from the church H. nemoralis 

 occurs in fair numbers — again unassociated with its ally — amongst a 

 luxuriant growth of ivy and bluebells. Vars. libellula 00000, 00300, 

 12345, 123(45), i(23)(45); rubella 00000, 00300, 12345, 123(45), 

 (i23)(45); and castanea 00300 — the last-named a particularly fine 

 shell — have been noted. 



(b). In a dense patch of nettles by the side of the road leading 

 out of EUastone village on the way to Ashbourne, H. hortensis is to
