forms of the vitrinoides type about Calcutta, one very flat with 
the base conspicuously concave about the umbilicus” (this I 
believe to be the same as the species from Cachar [Plate XX VII. 
fig. 2]); ‘it is very closely allied to M. lubrica, Bens. The 
other is a little higher and is said to be vitrinoides, Desh. Both 
are thin shells: the former appears to have no trace of spiral 
striation; in the other the striz become traceable when the super- 
ficial glossy polish is weathered off, but even then they are not 
nearly so strongly marked as in splendens” (vide Plate XXI. fig. 3). 
Stoliczka was therefore not making a comparison with such dis- 
tinctive sculpture as that shown on Plate XXI. figs. 9 and 10. He 
continues, ‘‘ Neither of these Calcutta species agrees sufficiently 
with the original description of Deshayes’s Helix vitrinoides ; but 
there have been so many other allied species (pedina, decussata, 
sequax, resplendens, &c., and lately one or two by Semper and 
Martens) described, that it would be unsafe to augment the already 
confused literature with new names without previously most care- 
fully comparing all the allied forms. Among all the Indian Zoni- 
tide the species of the vitrinoides type are certainly the most 
difficult of discrimination.” It is the second species alluded to, 
with sculpture like J/. splendens, that I consider to be JM, indica 
(Plate XVIII.), for its sculpture has the same arrangement of the 
spiral strie as in VW. petrosa (Plate XXI. figs. 1 and 2), a closely 
allied variety. 
Mr. Gray, when describing his genus Nanina, in which he in- 
cluded a H, vitrinoides, mentions Major-General Hardwicke’s draw- 
ing made in 1797; and he must have written his description of 
the animal partly from this drawing. In his ‘ Catalogue of the 
Pulmonifera in the British Museum,’ p. 73, although he makes 
H. citrina the type of the above genus, in the description and 
synonymy of /7. vitrinoides, p. 81, we find the P. Z.8. of 1834, p. 58, 
quoted, and with it a reference to Mrs. Gray’s ‘ Figures of Molluscous 
Animals,’ vol. iv. p. 111, t. 71. f. 5, for the animal. I have lately 
looked at the interesting original drawings at the British Museum, 
many of them signed Eliza Hardwicke. There are two distinct 
species of Macrochlamys given, Nos. 10 and 11; the first bears 
the date Futtehgurh, Aug. 1797, the second Dumdum, Oct. 1823; 
this last was the one copied into Mrs. Gray’s work, so that both 
have received the same specific title. As Hardwicke’s drawings 
constitute the first and original record of the genus Macrochlamys 
I give a description of them. 
No. 10. Macrocutamys pErrosa, ? Hutton. 
A very black-coloured species; body long, the lobe over the 
mucous gland very tapering and pointed. The right shell-lobe very 
narrow and long, and extending over the shell; the left shell-lobe 
also long and well developed. Shell of 5 whorls; colour ruddy 
brown. Major diam. 18-5 mm.=0°73 inch. 
Futtehgurh, which is not far from Banda, typical locality of petrosa.
