would be presumptuous on my part to suggest that the above list 

 exhausts the district, but I may be permitted to remark that of the 

 following shells the greater part appear to be undoubtedly absent. 

 In this list I do not of course include shells having special locali- 

 ties, as H. ohvuhita, H. Pisana, L. involuta, U. niargaritifer, &c.,&c. 



Faladina contecta. Helix fusca. 



Planorbis lineatus. Helix lapicida. 



Limnsea glutinosa. Bulimus montamis. 



Limnsea glabra. Pupa secale. 



Zonites radiatulus. Clausilia laminata. 



Zonites nitidus. Clausilia biplicata- 



Zonites excavatus. Acme lineata. 

 Helix cartusiana.

MOLLLTSCA OF BIRMINGHAM AND NEIGHBOURHOOD. 

 By G. SHERtllFF TYE. 



There aie 310 species and varieties of MoUusks described as 

 inhabiting Great Britain : — 



46 species 91 varieties, Fluviatile. 

 78 „ 95 „ Terrestrial. 



Total, 124 186 



There are included in the following list 151 species and varieties, 

 viz ; — - 



38 species 45 varieties, Fluviatile. 

 44 „ 24 „ Terrestrial. 



Total, 82 69 



Thus it will be seen we have nearly 50 per cent, of the whole 

 number. Taking into consideration the species inhabiting exclusively 

 maritime situations, and such as are restricted to one kno^vn locality, 

 varieties dependent upon peculiar situations and others which are the 

 result of accident, we shall find that our district (which includes a 

 portion of the counties of "Warwick, Stafford, and Worcester,) offers 

 a good "hunting ground" to the collector. 



All the species enumerated are — with the exception of Helix 

 mrgata* II. Caniiana., and Balea perversa — confined within a circle 

 of ten miles radius, taking Birmingham for its centre. These species 

 have not hitherto been met with within this boundary, and we have 

 thought it best to include them, as the outlying district is being 

 " worked," and we know not where else their existence will be re- 

 corded. In any future tabulation of the " localities " of the Mollusca 



* Helix riraata. One dc.ntl shell was found in a'sandstonc quarry at Scllr-Oak,althougb 

 any other evidence of its ever having existed there cannot bo fuuiul.
