MACROCHLAMYS. 99 



M. leci/fJtisis known from ,17. snhjecta and 21. vesicida, Benson, 1852, 

 by having the aperture distinctly wider than high. [I consider 

 vesicula, Es., 1852, = leci/iJiis. This and snhjecta are species so 

 extremely close to one another that I doubt their distinctness. 

 They cannot be matched with shells of this type from Assam and 

 neighbouring hill-ranges.]

(uo description), pi. 26, fig, 8. [This shell, from Jeypur, differs 



much in form, and may prove to be distinct.] 



Similar to J/, indica, but more depressed and with the spire 

 almost flat, the surface smooth, and the perforation larger; whorls 6, 

 the last broader; aperture broadly lunate, coliimellar margin but 

 little carved, oblique throughout, slightly expanded for some 

 distance, more so at the perforation. 



['' Macrochlamys (Parisnath). — Shell of flattened form. Both 

 mantle-lobes (i, e. shell-lobes) very long and narrow ; mantle 

 greenish, splashed with white. Whole body of a distinct greenish 

 tinge ; anterior part, especiall}' on the pedicles and back, black ; 

 middle part pale ; posterior part dark above, less dark at the sides."

 The outer laterals are not, as in most allied species of Macro- 

 chlamys, bicuspid, but they are long and straight ; those inside near 

 the inner laterals have a minute Jiotch near the apex ; the inner 

 laterals and medians bicuspid as usual, the outer cusp small.
