Helix metaformis. De F. var. . 
It seems proper to notice the following additional varieties of this 
species, varieties which have been found by Mr. Cuming in the 
Philippine Islands, viz.— 
a. Shell pale yellow brown, irregularly covered with a very pale 
hydrophanous epidermis; circumference of the columella nearly 
black; one pale brown band anterior to the circumference of the 
shell; apex white. Found on leaves of trees near Manilla. 
b, Shell pale yellow brown; apex white; circumference of the 
columella nearly black; a pale brown band close behind the suture 
of the first volutions. Found on leaves of trees near Manilla. 
ec. Shell light brown, paler near the apex, which is reddish brown ; 
circumference of the columella nearly black; two narrow brown 
bands, one of which is placed at the cireumference of the shell, and 
the other close to the suture in front. Found on leaves of trees 
near Manilla. 
d. Shell light brown, with a dull hydrophanous epidermis, paler 
toward the apex, which is dark mahogany brown; circumference of 
the columella nearly black ; two broad, very dark brown bands, one 
of which is placed at the circumference of the shell, the other close 
to the suture in front. Found on leaves of trees at San Mateo, in 
the province of Tondo, isle of Lugon. 
e. Shell brown, with a lighter coloured irregular hydrophanous 
epidermis ; paler near the apex, which is dark brown; circumference 
of the columella very dark brown; two brown bands nearly similar 
to those in var. c. ‘This is rather a coarse variety, and appears to 
be a slight example of monstrous growth, its spire being rather un- 
usually elevated, and the volutions consequently more prominent. 
Found on leayes of trees near Dolores, province of Pampamga, isle 
of Lugon.

Mr. Cuming has obtained three varieties of this species, viz. :— 
a. Colourless. 
6. White, a broad nearly black belt surrounding the columella, a 
pale reddish brown band at the circumference of the shell, and a 
darker brown antesutural band articulated with white hydrophanous 
specks of epidermis; apex dark brown. - 
ce. Shell white, with a broad nearly black belt surrounding the .
