The shell has a curious resemblance to the Malabar JZ. basileus, 
Bens., both in form and in its peculiar sculpture. 
The occurrence of ZZ. distincta at Chieng Mai has already been 
recorded by Morlet, Journ. de Conch., 1891, p. 231. 
[‘* Very common at Pitsunaloke, but rare in the North Laos States. 
Generally found in forests of the ‘Eng’ (Dipterocarpus tuberculatus). 
After a (forest) fire in the hot season it is a common occurrence to see 
eight or ten dead shells all together im the hole of a tree. The Laos 
eat this snail, and pronounce it ‘sweet and delicious.’ ””—W. M. D. | 
8. Hemiptecta? Danaz, Pfr. Pitsunaloke. 
Three specimens sent show some variation. Two agree well with 
the type in the Natural History Museum, the third has a higher spire. 
The original type was obtained by Mouhot, and was said (Proc. Zool. 
Soe., 1862, p. 268) to be from ‘‘ Lao Mountains, Cambodia.” It is 
scarcely necessary to say that the Laos are a people who inhabit 
Northern Siam, not Cambodia. 
[‘* Found at Pitsunaloke in bamboo jungle, but not common. I have 
not met with a single specimen in the Laos States.”—W. M. D. ]

10. GaneEsELLA capitium (Bens.). Ann. & Mag. Nat. Hist., ser. 1, 
vol. 1 (1848), p. 160. 
The occurrence of this shell in Siam had already been noted by 
Morelet (Ser. Conch., iv, p. 254). As I pointed out in 1865 (Journ. 
Asiat. Soc. Bengal, vol. xxxiv, p. 93), Helix hariola, Bens., is not 
distinguishable from Ganesella capitium, although the latter is keeled 
and the former is not. 
Including G. hariola, G. capitium has a very wide range, being 
found in Southern India (Nullymalay Hills), Behar, both south of 
the Ganges and at the base of the Himalayas, Upper Burma, Pegu, 
and Siam from the north to Bangkok. 
The Siamese specimens sent are sharply keeled, and resemble Indian 
shells (typical G. caprtiwm), except that they are lower in the spire. 
[‘‘ Found all over Siam, but not common.’’—W. M. D. | 
11. Herrx (Piecrorrorrs) Orpnam, Bens. Lampun. 
This is another rather widely ranging form, being known previously 
from Assam to Pegu. 
Specimens of HH. tapeina, Bens., and ZH. ZHuttoni, Bens., were also 
received. Neither of these has a precise locality, and it is not quite 
certain whether they were really from Siam.

Several shells sent by Mr. Daly appear to me to belong to the above 
species, var. B (Proc. Zool. Soc., 1861, p. 207). They are small,
