328 JOURNAL OF CONCHOLOGY, VOL. 9, NO. II, JULY, I9OO. 



Var. minor. — Not uncommon in some parts of the Burrows, at 

 Caldy Isle, and near the old quarry at the bottom of Heywood Lane. 



Var. hyalozonata. — Rare, one specimen from St. Catherine's 

 Rock, one from the Burrows, and two from Manorbier. At Pembroke 

 Castle there is a small colony, living with H. virgata, vars. alba and 

 hyalozonata, and H. acuta var. alba. Some of these H. itala are pure 

 white without bands, and should properly be called var. alba to 

 correspond with that variety in H. pisana and H. virgata. The 

 common whitish form with a dark nucleus (var. alba Charp.) should 

 be called var. albida or better still var. albicans. 



Var. leucozona. — Fairly common at Giltar; intermediate forms 

 between this variety and the type are common on the Burrows, and 

 round Holloway Quarry. 



Var. albida (=var. alba Charp.). — Abundant everywhere with 

 the type. 



Var. lentiginosa. — Common on the Burrows and round 

 Holloway Quarry. 



H. caperata. — Very abundant and widely diffused. It is very 

 hardy and may be observed crawling about in mid-winter, even in a 

 biting east wind. It is a great climber, especially in a young state, and 

 on the Burrows, where walls and trees are wanting, it uses the tall 

 stems of the Ragwort to roam over. Scalariform specimens are 

 occasionally met with. 



Var. Sllbscalaris. — Not uncommon with type in a few places. 



Var. major. — Not common. 



Var. ornata. — Common. 



Var. fulva. — Common; both light and dark shades are found, 

 and it is sometimes speckled. 



Var. obliterata. — Two good specimens from Holloway Quarry 

 (AGS.); and one from the Castle Hill (C. E. Wright). 



H. virgata. — Very abundant, and exceedingly variable in colouring 

 and markings. The shells are, as a rule, small, but there are many 

 sheltered places on the Burrows where they grow to a fair size; 

 specimens from 16 to 18 mm. being not uncommon in some low-lying 

 spots between the hillocks. On the tops of the hillocks the shells are 

 as a rule smaller than in the hollows and flat places between the 

 mounds, though they are usually more numerous in the first place. 

 The purple-tinged specimens, so common at Giltar and Manorbier, 

 may possibly owe their abnormal colouring to their very exposed and 

 marine position, though I have taken the same form in the low-lying 

 Ritec Gardens.
