24 G. 'NeviW— List of the Mollusca of [No. 1, 



by its flattened, more ear-like and appressed shape. It also somewhat 

 resembles Helic. Peguensis, Theob., J. A. S. B. 1834, p. 8, from Prome ; it 

 is, however, a larger and thicker shell, with the whorls of the spire much 

 broader and more distinct, and considerably less open at the base ; in many 

 resjoects it is intermediate between the above two species, though all three 

 are easily recognisable and quite distinct. 



Type of Selic. resplendens, diam. max. 22, lat. 14, crass. 8 mil. 



Helic. gigas, (small specimen), diam. 22, lat. 16, crass. 10 mil. 



JEEelic. Peguensis, diam. 17, lat. 10, crass. 5 mil. (a rather larger speci- 

 men than the type). 



Four specimens of this interesting form were found at Sawady. Dr. 

 Anderson also brought back a single specimen (in spirit) from Bhamo 

 (5000 ft.) which clearly shows the animal to be of a light pinkish colour, 

 very sparsely dotted with black specks, except on the mantle lobes and caudal 

 extremity, which are thickly dotted ; in this specimen the spire of the 

 shell only is covered by the animal, though the mantle lobe has no doubt 

 shrunk.

 Vitrina gigas, Bens., J. A. S. B., 1836, p. 350 (Sylhet). 



A single specimen was found at Kyoukphoo ; though differing slightly, 

 it is so close to the shell of typical Helic. gigas, that I think there can be 

 little doubt of their identity. 



Diam. 35|^, axis 8|^ ; apert. lat. 27i, alt. 21 mil. 



Helicaeion magnipicus, n. sp,, G. A. and Nev., 



I am indebted to Major Godwin- Austen for pointing out that this 

 magnificent slug, the largest yet known of the genus, is quite distinct from 

 Benson's Helic. gigas (Khasi Hills) ; Godwin- Austen has kindly undertaken 

 to describe the animal with full details and a figure, so that it is only neces- 

 sary for me here to state that it is very closely allied to the Assam 

 species, but that the shell is much larger, of a brown (not green) colour, with 

 the body-whorl much more flatly expanded, and the spire less convoluted 

 and more depressed, and that, looked at from underneath, very much less 

 of the reflected body- whorl is visible. 



The largest specimen, in spirit, measures 70 mils. 



Shell, diam. maj. 46, axis, 11|^ ; apert. lat. 40i, alt. 29| mil. 



Tolerably abundant at Momein in Yunnan, at 5,500 ft.

Dr. Anderson brought back, from Ponsee in Yunnan, numerous speci-
