366 THE ZOOLOGIST. 



H. neinoralis, Linn. — Abundant ; taken in company with 

 H. arbustorum on boggy ground by stream close to South 

 Hincksey. The varieties numerous and very fine, among which 

 I have some forms, of an unusual uniform green and dull purple 

 colour, that I have not seen elsewhere. 



H. hortensis, Miiller.* — Very frequent, though not so abundant 

 as the preceding species. At Radley I found this species with 

 nemoralis and arbustorum. The var. hybrida I have taken on a 

 hedge near Shotover Hill, and Mr. Whiteaves took it on nettles 

 in Barton Lane and at Stanton St. John's. 



H. arbustorum, Linn. — Very plentiful in moist places by river- 

 and stream-banks. The var. flavescens is not uncommon near 

 South Hincksey and Radley. Vars. major and alpestris rare ; near 

 South Hincksey. 



H. cantiana, Montagu. — This species seems now to have a 

 wider extension than in 1857, when Mr. Whiteaves recorded it in 

 his list as limited to the Headington district. I have obtained 

 it near South Hincksey, at Kennington, near Stonesfield, at Stow 

 Wood, in quarries of coral-rag near Cowley and Horsepath, and 

 of Portland sand on Shotover Hill. In quarries it is generally 

 discovered under loose stones and debris, but its usual habitat is 

 nettles and other plants by roadsides and hedge-banks. Hardly 

 ever taken off calcareous subsoils. 



H. rufescens, Pennant. — Very abundant everywhere. 



Var. albida. — Common. 



Var. conica. — Frequent, especially among dead leaves in woods. 



Var. minor. — Rather common. All three varieties are found 

 sometimes together. 



H. concinna, Jeffreys. — Rather frequent on roadsides and 

 hedgebauks under stones and among nettles ; South Hincksey, 

 Stonesfield, Garsington and Wheatley. I have it also from 

 Kingham, about twenty-three miles N.W. of Oxford. 



H. hispida, Linn. — Very abundant, especially in wet places. 



Var. albida. — Under stones at Islip and at Stonesfield. 



H.virgata, Da Costa. — Abundant in calcareous districts. The 

 bandless variety is always found with the banded form. 





* In the opinion of Dr. Gwyn Jeffreys it is impossible to distinguish 

 Helix hortensis from H. nemoralis except as a variety, the former being 

 more northern, and the latter more southern in geographical distribution.
