A brilliant chatoyunt i-eflection, like Labradorlte, is to be observed 

 on the polished surface of the dark brown reflected part of the outer 

 lip in fresh specimens.

Tliis variety was the most abundant, and Mr. Cuming informs me 

 that he detected it in the act of depositing its eggs on the leaves of 

 trees in the forest where it was feeding. The eggs, which are white, 

 oblong, and covered with a hard, granular shell, were attached to 

 the leaves by a gummy substance. They are half an inch long, and 

 nearly four-twelfths across in their widest part.

In this variety, the abrupt termination of the yellowish markings 

 toward the basal portion of the body-whorl leaves the dark colour 

 almost uninterrupted, in the shape of a dark band.

Near the umbilicus, the epidermis, in those specimens of var. k. 

 which I have seen, is worn off, exposing the rich red-brown ground 

 colour of the shell. Indeed in all the varieties the dark colour ge- 

 nerally appears to reside in the shell itself, and the lighter-coloured 

 markings, with few, if any exceptions, in the epidermis. In the 

 largest variety (a) here described, the effect of the detrition of the 

 epidermis is well shown. Var. k. comes very close ujDon var. c. of 

 Bulinus chrysalidiformis. The length of this species is 6 inches and 

 under, and the breadth from about 1 to l^th of an inch.
