THE LAND AND FRESHWATER SHELLS 

 OF TENBY, SOUTH WALES. 



By ARTHUR G. STUBBS. 



(Continued from page 328). 



Helix virgata (continued). 



Var. lineata. — Common, especially so on the Burrows near 

 Giltar. 



Var. minor.- — Common, fields on the North Cliff, Jubilee 

 Gardens, Castle Hill, etc. 



Var. leucozona. — Common in the Jubilee Gardens, below the 

 Wreck Field; also at Giltar and Manorbier. Intermediate forms 

 between this variety and the type, showing the band plainly above the 

 periphery, are not uncommon. 



Var. maculata. — Abundant, the handsomest specimens coming 

 from the Burrows round the Black Rock and Holloway Quarry. 

 Shells from the first-mentioned place have often a maculated band up 

 the spire, but it fades away near the mouth leaving the greater part of 

 the last whorl plain white; usually there are no bands below the 

 periphery in this form. 



Var. radiata. — An exceedingly beautiful form of this variety is 

 to be found on St. Catherine's Rock, but it is rare. Another paler 

 form has been taken in a very limited area of the Jubilee Gardens and 

 is also rare. Intermediate forms between this and var. picta are not 

 uncommon in a few places. 



Var. picta. — Not uncommon on St. Catherine's Rock, in the 

 Jubilee Gardens, at Giltar, and at Manorbier. The Giltar and 

 Manorbier specimens have often a purplish tinge. Intermediate forms 

 between this variety and the type, and vars. leucozona, moira, and 

 radiata are often met with. 



Var. moira. — Cottage gardens by the Ritec, at Giltar, and at 

 Manorbier. It usually lives in company with the next variety. 



Var. nigrescens. — St. Catherine's Rock, Jubilee Gardens, 

 Ritec Gardens, Giltar, Manorbier, and occasionally on the Burrows. 

 My finest specimens come from the Burrows, one measuring 16 mm., 

 but this is an exceptional size for this variety, which is usually rather 

 small. It is most common at Giltar, where it is often blotched with 

 a purple tinge. 



Var. hypozona. — Abundant in most places. The largest speci- 

 mens come from sheltered spots on the Burrows and measure from 

 16 to 18 mm. 



Var. albicans. — Common. 



Var. lutescens. — Abundant, and always found with the type.
