[Var. viridescenti-alba].— Wall by Penally Station {fide the

H. aculeata. — Hoyle's Mouth, but not plentiful; it seems to

 Gumfreston Marshes, and occasionally elsewhere. 



Var. costata. — Common on old walls at Giltar, the Castle Hill, 

 St. Catherine's Rock, and Hoyle's Mouth. In drier situations than 

 the type in this neighbourhood, though both have been taken together 

 from under stones on Gumfreston Marsh. 



H. aspersa. — Very abundant and very variable. The cleanest 

 and handsomest specimens come from the South Cliff and Jubilee 

 Gardens. They swarm on the Burrows and at Giltar. 



Var. conoidea. — Common on the Marsh Road and Castle Hill. 

 Var. globosa. — Not uncommon on the Burrows near the Black 

 Rock, the Jubilee Gardens, and the Wreck Field.

 Var. nigrescens. — Occasionally on the North Cliff, and in

 Var. rufllla-zonata nov. — Three specimens of a form having the 

 same ground-colour as the last variety but with translucent reddish 

 bands have been taken, two from the Narberth Road, and one from 

 Deer Park. A very lovely shell. 



Two scalariform monstrosities have been found, and a curious 

 specimen much compressed at the sides, giving it a squarish outline. 



H. nemoralis. — Abundant on the Burrows, on the railway banks, 

 at Giltar, etc., but very local. Shells from the Burrows are generally 

 large and thick, the bandings 12345, (12)345, 00300 and 00000 being 

 most often met with, though two of the rare banding 12045 have been 

 taken. On the North Cliff there is a pale form of var. libellula 00300
