MELANIIDJ!. 255 



var. hainesiana. 



Melanla haiuesiana. Lea, Proc. Acad. Nat. Sci., Philad., 1856, and Observ., 

 pi. 22, fig. 18, India ; Benson, J. A. S. £., 1836, pi. 746, as M. variabilis, 

 var. C.from Sylhet, 



Benson, 1. c. " Laevis liris costulisque obsoletis, anfractus 

 ultimi medio subcarinato, adulti nodulis humeralibus frugal iter 

 sparsis." This form is not figured in tbe 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. Cacbar ; 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 aud Gowhatty [Assam] ; coll. Dr. F. Stoliczka, &c. 



Spire produced, longitudinal ribbing almost or altogether 

 obsolete, basal sulcation subobsolete ; a single specimen is very 

 interesting, showing the transition to my var. semilcevigata, 

 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 [? typical 31. 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. Chennell, Esq. 

 16 Gowhatty ; coll. Museum Collector. 



This is the most distinct and interesting form of the variety 

 that I have seen ; it is of unusually thick substance, not de- 

 collate ; spire peculiarly short, of 10 whorls ; uniform bright
