Shell with its spire very much elevated, with five ventricose 
whorls, with its suture very deep. 
Animal ash colour, head and neck blackish above, spotted 
with yellow. Tentacles very long, ash colour, sprinkled with 
pale olive. Foot hyaline, ash colour, sprinkled with opaque

Inhabits the marshes in the neighbourhood of London, and 
is very common also in ditches near the Surrey Canal. It has 
since been found in Campsey Mere and Holbrook Stream in 
Suffolk by my learned and worthy friend the Rev. R. Shep-

3. BITHYNIA INFLATA.

Animal pallidé testaceum aut cimereum, nigrescente punctu- 
latum. Tentacula longissima, cinerea, olivaceo irrorata. Pes 
cinereus, hyalinus, albido irroratus; fascia utrinque supra et 
punctulis nigricantibus aut flavidis effecta. 
Habitat in stagnis; et in paludibus inter Bexhill et Castellum 
Pevensey dictum vulgatissimé. 
The shell with its spire very much elevated; with five im- 
flated whorls, with its suture very broad and very deep. 
The animal pale, testaceous or cinereous, punctulated with 
pale black dots. The tentacula very long, cinereous, sprinkled 
with olive. The foot cinereous and hyaline, sprinkled with 
whitish, with a band on each side above formed of blackish or

I discovered this new species in a small pool near William 
the Conqueror’s table near Hastings, and afterwards very 
abundantly in the marshes between Bexhill and Pevensey Castle 
and in the moat on one side of the Castle.
