hood of Stourbridge and Kidderminster ; then a narrow strip of 

 Lower Keuper sandstone stretching from Witley to Hagley and bend- 

 ing eastwards as far as Bromsgrove, where it joins the Keuper marl, 

 stretching roughly from the south-western to the north-eastern corner 

 of the county. The Wenlock limestone is represented in the county 

 around Tenbury and Clifton-on-Teme, while, the Coal Measures 

 appear in the Wyre Forest district. The Lower Oolite occurs on 

 Bredon Hill. 



There are several detached portions belonging to Worcestershire, 

 but situated as " islands " in Gloucestershire or Staffordshire, but for 

 conchological purposes these detached portions are included with the 

 county which surrounds them ; for this reason we cannot claim Ena 

 montana amongst the Worcestershire moUusca, as it is only recorded 

 from one of these " islands," Dovedale, Blockley. 



The county is watered by the Severn, the Warwickshire Avon, and 

 the Teme, besides lesser streams. The Severn enters the county at 

 Arley in the nortii, and passing through Worcester is joined on the 

 Gloucestershire borders by the Avon at Tewkesbury. The Teme 

 joins the Severn at Powick near Worcester. Worcestershire has no 

 natural lakes, but there are several large artificial reservoirs and orna- 

 mental pools, as at Cofton Hackett, Pirton Pool, and Westwood Park 

 near Droit wich. 



It will be apparent from the lis't; now given that only a very small 

 portion of the county has been worked at all thoroughly from a 

 conchological standpoint, and doubtless several further species 

 (particularly in Plsidium) might be added to the list by workers in 

 hitherto unexplored localities, while the distribution of many appar- 

 ently rare species would be found much wider than we are at present 

 led to believe. The southern portion of the county has been the 

 most worked, especially the Malvern district, but as mentioned above 

 one cannot place too much reliance on old records of limestone-loving 

 species from "Malvern"; these generally refer to a limestone ridge 

 at West Malvern, which was formerly a part of Worcestershire, but has 

 in recent years been ceded to Herefordshire. As it is the most pro- 

 ductive locality for shells near any of the Malverns it has naturally 

 received considerable attention from all local collectors ; Fyraiiiidula 

 rotundata var. alba Moq.-Tand. is not uncommon there as well as 

 several species that are rare within the county boundary. 



Careful examination of river rejectamenta may yield some more 

 species to the list, but I must confess to having obtained very little 

 result from examination of a quantity of debris from the Severn after 

 floods. The Avon and Teme would probably give better results. 



In Dr. Griffiths' list Hygromia granulata {^^^ Helix sericea") is said
