ADAMS: INTERESTING KENTISH FORMS, 317 
siderable portion of the epiphragm still remaining nacred 
over so as to become part of the shell. This formation of 
nacre parallel with the epiphragm is not uncommon, as I 
have several specimens to show. I took a specimen in this 
locality in 1891 with a much thickened inner lip, and a 
detached pearl nearly spherical 4$ x 5} mm., which is the 
only instance I know of a land pearl. 
H. aspersa swarms over the whole county, and though there 
is a certain ‘“‘family likeness” in the usual form taken in 
the county, approaching var. zovazu, there are many striking 
varieties found. At the foot of the Shakespeare Cliff there 
is a colony of small shells (hardly mnor), and thin when 
compared with others similarly situated. The zwzzcolor 
Mog. (gvisea Jeff.), too40 occurs near Canterbury, and 
the exalbida form is by no means rare. The Rev. J. W. 
Horsley, with whom I spent a most enjoyable week of 
collecting, drew my attention to its predilection for the 
“traveller’s joy,” some plants of which yielded four or five 
individuals of this variety. 
H. nemoralis seemed scarce this year compared with its 
abundance in the same spots on previous occasions. 
H. hortensis, however, fully compensated for the short coming 
of its big brother, the following forms being met with : 
Var. lutea, 00300, 10345, 10045, 00045, 12045, 00005, 00050. 
Var. lutea-fuscolabiata, oocoo. 
Var. albina-fuscolabiata. 
Var. albina, many extremely diaphanous. 
Var. citrina-zonata, 00300. 
Var. Carnea, translucently banded 00300, fuscolabiata. 
Var. carnea-roseolabiata, 00300. 
Var. carnea-roseozonata, ,1233(45). 
Var. lilacina. It is worthy of remark that the red, white, and 
lilac forms are very small and diaphanous, though living 
directly on the chalk.
