Original description :—“ Length of spirit-specimen 45 to 60 mm. 
* Length of the mantle 25 mm. 
“Colour ash-grey or blackish. 
«Internal shell 11 mm. long, 74 broad, massive, thick, flat. 
“Jaw with 16 ribs. 
“ Radula 125 rows of 90 teeth.

‘Middle tooth broadly triangular, with moderately long points ; 
the side points are somewhat broader at the base ; side teeth hardly 
differ from the middle tooth, inclined inwards. The shape does not 
perceivably change even towards the side, only at last the side point 
disappears, 
“The young animal. On the back part of the mantle is a black 
spot, which runs in a point in front and encloses a small space, 
which is brighter than the rest of the mantle. The sides of the 
mantle are black-spotted, and down the sides of the body runs a 
black stripe, which towards the back is sharply marked out, but 
towards the sole is shaded off; the top of the back is again some- 
what darker. 
“Tt is very probable that, as in the case of many European slugs 
which in their young state are similarly coloured, this coloration 
disappears through the darkening of the whole skin. 
“Habitat. Sikkim ; Simla to Sultanpur; Bias at Bishisht, Kulu ; 
Bias Kund, Rotang Pass. 
‘“* As these two forms were obtained from different localities, we 
may consider the species to be generally distributed and common ; 
according to Schlagintweit it exists at 13,420 feet. In all proba- 
bility their food is fungi.”

Description from spirit-specimen. Animal large. The mantle 
apparently finely papillate in life. The foot above very coarsely 
wrinkled, rounded at extremity. No gland. <A very narrow pedal 
margin. ‘The respiratory orifice at the posterior right margin or 
about one third the length of the mantle from the posterior side. 
The eye-tentacles would appear to be very large at the base. The 
mantle, viewed from above, is rather circular in form. The foot 
has a wide central area. 
Total length 101-6, mantle 38-0, breadth 31°83 mm.

Jaw is well ribbed, and 0-2 inch or 5:1 mm. wide. 
There is only one specimen at the British Museum, and therefore 
Iam unable to give any details of the anatomy of this species, of 
which no doubt some will be found in the Indian-Museum collec- 
tion, Calcutta. The gigantic specimens alluded to by Mr. G. Nevill, 
in the mollusean portion of the ‘ Scientific Results of the Second 
Yarkand Mission,’ under Anad. altivagus, | well remember his showing 
me in Calcutta. They are certainly very distinct from the Simla 
specimens I have seen, and much nearer A. jerdoni in outward
