MELANIIDA. 255 
var. hainesiana. 
Melania hainesiana, Lea, Proc. Acad. Nat. Sci., Philad., 1856, and Observ., 
pl. 22, fig. 18, India ; Benson, J. A. 8. B., 1836, pl. 746, as M. variabilis, 
var. C. from Sylhet. 
Benson, l.c. “ Laevis liris costulisque obsoletis, anfractts 
ultimi medio subcarinato, adulti nodulis humeralibus frugaliter 
sparsis.” This form is not figured in the Con. Indica, or in 
Reeve ; Brot merely gives a copy of Lea’s figure, and that a bad 
one, as he makes the basal sulcations far too developed. lea, in 
his description, notes that “ one of his younger specimens has a 
disposition to indistinct folds towards the apex.” 
8 Khasi Hills, N. Cachar ; coll. Colonel H. H. Godwin-Austen. 
Agree exactly with original figure, which is, however, that 
of a not quite adult specimen. 
1 Dihiri Hill [Brahmaputra watershed]; coll. Colonel H. H. Godwin- 
Austen, 
Less characteristic and nearer typical M. variabilis ; subobsolete 
longitudinal ribbing being distinctly traceable, the last whorl 
less distinctly angulate, and the spire more produced. 
16 Tezpore and Gowhatty [Assam] ; coll. Dr. F. Stoliczka, &. 
Spire produced, longitudinal ribbing almost or altogether 
obsolete, basal sulcation subobsolete ; a single specimen is very 
interesting, showing the transition to my var. semilevigata, 
there being five small, but distinct, nodules behind the outer 
lip, midway between the peripheral keel and the suture. 
1 Sibsagar ; coll. S. E. Peal, Esq. 
Like the above Tezpore specimens, but the last two or three 
whorls are biangulate, or rather bi-carinate. 
4 Sylhet ; ex c. Asiatic Soc., Bengal [P typical MW. variabilis—var. C, 
of Bs.]. 
One of these is also bicarinate on the last whorl. 
2 Gowhatty ; coll. Museum Collector. 
3 Naga Hills ; coll. A. W. Chenne!l, Esq. 
16 Gowhatty 3 coll. Museum Collector. 
This is the most distinct and interesting form of the variety 
that I have seen; itis of unusually thick substance, not de- 
collate; spire peculiarly short, of 10 whorls; uniform bright
