ZONITIDA. 7 
Vitrea LucIDA, Draparnaud (= Hyalinia draparnaldi, Beck). 
Apparently rare; possibly often confused with V. cellaria. 
It is sometimes a little difficult to distinguish between the 
shells of these species, but the deep slaty-blue colour of the 
animal, extending even to the side areas of the sole, serves at 
once to distinguish V. lucida from V. cellaria. 
North. 
Abundant in gardens at Hill Road, Weston-super-Mare ! 
South. 
Mr. John Taylor received one specimen from Mr. Pon- 
sonby which was presumably taken at Brympton. 
Var. albina, Moquin-Tandon. Specimens in the Bristol 
Museum are said to have been taken in Somerset. 
VITREA CELUARIA, Muller (= Hyalinia cellaria, Westerlund, 
and Zonites eellarius, Moquin- Tandon). 
Generally distributed in woods and open country, also in 
the vicinity of human habitations. Animal pale-grey. I have 
observed it in a Holocene deposit on Brean Down, Weston- 
super-mare. 
Var. compacta, Jeffreys. 
A somewhat flatter form, found by Mr. Hugh Watson at 
Dulverton, is recorded in Taylor's Monograph, Vol. II, 
p. 37. This variety is intermediate between V. lucida 
and typical V. cellaria, having the shell of the former 
and the anatomical structure of the latter. 
Var. albina, Moquin- Tandon.

Holbrooke, Bratton St. Maur! 
Dulverton; H. Watson. 
Virrea roceHRSI, B. B. Woodward (=Hyalinia helvetica, 
Auctt, and Zonites glaber, Jeffreys). 
Apparently a very local and rare species: it may be assumed, 
however, that it occurs in the recesses of the majority of the 
larger woods in the county. 
North. 
Creech Hill, near Bruton ! 
Weston district; FP. A. Knight.
