the sculpture above is considerably coarser and more developed, the columel-

 more produced and rounded.

The types of this species from Sylhet are in the Indian Museum. It 

 is a form with an unusually open umbilicus, a single spiral brown band, and 

 a rather flat spire. Major Godwin-Austen has also presented similar 

 specimens from the Khasi Hills. A closely allied form is abundant in Ara- 

 kan and Bassein ; this only differs by the umbilicus being a trifle less open ; 

 it is well represented in the Con. Indica, pi. 14, fig, 10. Close to both the 

 preceding are six specimens found by Dr. Anderson at Bhamo, umbilicus 

 like that of the type form, suture a shade more excavated, slightly smaller 

 in size. \2iT.fasciata, Godwin- Austen, J. A. S. B. 1875, pi. 1, fig. 1, is abun- 

 dant at Seebsaugor in Assam ; it only differs by its colouration. For the 

 shell figured in the Con. Indica, pi. 14, fig. 9, I suggest the name of var. 

 Jchasiensis ; the raised and rounded whorls, less open umbilicus, and contract- 

 ed aperture well distinguish the form ; it has sometimes a single brown 

 band, but is oftener without it ; it is tolerably abundant in the Naga and 

 Khasi Hills.

There is no specimen in the Museum from Bengal of either of the 

 shells called H. ca/pitium or H. Jiariola, but I am informed by Mr. W. T. 

 Blanford that he has in his collection specimens of typical II . capitium, 

 from the Ganges Valley and from the NullaymuUay Hills in Southern In- 

 dia, and that he is convinced that the form in Upper Burma, first found by 

 himself in 1861, cannot be distinguished. Morelet, Ser. Conch. IV, p. 254, 

 1875, records a most interesting locality for H. capitium, viz., Bangkok in 

 Siam. On the other hand the Museum possesses both forms from Burma, 

 from Prome the form figured in the Con. Indica, pi. 14, fig. 6, as H. hario- 

 la, and from Ava that figured. on the same plate, fig. 5, as H. capitium; the 

 latter Dr. Anderson also found at Kalawat in Upper Burma ; the two forms
