MOLLUSCA OF INDIA. 245 
no dart-sac, the spermatheca short, a globular sac on a short tube ; 
the male organ simple, bent on itself at the retractor muscle. The 
spermatophore is very peculiar, and is formed in an expansion of 
the tube, where the vas deferens unites withit. The albumen- 
gland very large. 
This is an extremely interesting species, for in many respects it is 
similar to A. pallens, from Abyssinia, the differences that are to 
be found being only modifications of the same parts in the latter. 
There are several varieties in Colonel Beddome’s collection, from 
the same hills, differing only in colour: these I indicate as follows :— 
Var. arrrrma. (Plate LVII. figs. 3, 3a, 36, animal; figs. 4, 
4 a, shell.) 
This would appear, when living, to be a rich grey-black, the sole 
of the foot, which in ater is entirely pale, is in this variety bordered 
with black, only the ambulatory central area being pale brown ; on 
each side of the extremity of the foot there isa blacker band of 
colour. 
Var. cinereus. (Plate LVII. fig. 8, animal.) 
Is of a pale ash colour, with a distinct dark band on the side of 
the foot behind, which is again seen on the side of the head ; the rest 
of the body and mantle are mottled throughout. 
Var. CASTANEUS. 
Is a rich chestnut, with dark markings similar to the last two. 
These varieties (divergency confined to coloration alone) are just 
what we find in such forms as Arion ater in Europe. 
To Colonel R. Beddome conchologists are indebted for the collec- 
tion of this extremely interesting species, and its preservation in 
spirit, which has enabled me to now give them its description ; and 
I take this opportunity of thanking him for placing it and so many 
other shells in my hands.
