ral varieties, all remarkable for a more or less russet brown hydro- 

 phanous epidermis. They are 



a. Shell of a nearly uniform colour, rather lighter near the suture, 

 and very irregularly speckled with dark brown shining spots, caused 

 by the partial abrasion of the epidermis. From the mountains of 

 the Igorrotes, in the northern part of the island of Lueon. 



b. Shell of an uniform brown, with a nearly white sutural band 

 interrupted with brown shining spots. From the same locality. 



c. Shell of a light brown colour, with a dark band surrounding 

 the last volution. Found on leaves of trees at Sual, in the province 

 of Pangusinan, island of Lucon. 



d. Shell of an uniform light brown, speckled with dark brown, 

 and with a dark brown antecircumferential band. Found on leaves 

 of trees at Dolores, in the province of Pampamga, isle of Lue.on. 



e. Shell small, of an uniform brown, with a nearly white ante- 

 sutural band, and a pale band near the circumference of the last 

 volution. From the mountains of the Igorrotes. 



f. Shell brown, longitudinally streaked with nearly white, and 

 having a nearly white antecircumferential band. Found on leaves 

 of trees at Gattananga, in the province of Cagayan, island of Lu^on. 



g. Shell of an uniform dark brown. This appears to be a dwarf 

 variety, being much shorter in its proportions than the others. 

 Length 1*5 ; breadth T05 of an inch. Found on leaves of trees at 

 Sinait, in the province of South Ilocos, in the island of Lucon.

The following varieties of this interesting and elegant species have 

 occurred to Mr. Cuming : — 



a. Shell somewhat striated, striae forming the lines of growth, 

 many of those on the under side white, pale brown with brown bands 

 (one at the periphery, one close to the suture, and one beneath). 

 Distant, squarish, striated patches of white epidermis ornament the 

 broad band in front of the suture : aperture white : found at Ca- 

 lauan. 



b. Shell slightly striated, striae as in the last, forming the lines of 

 growth ; ground colour pale yellowish brown, with a rather darker 

 brown band close in front of the suture, a narrow brown band at the
