MACROCHLAMYS. 



M. lecythisis known from M. subjecta and M. vesicula, Benson, 1852, 

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

 vesicula, Bs., 1852, = lecyfhis. This and subjecta 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.]

of animal taken from that by Stoliczka]. 

 Macrochlamys stricklandi, Godwin-Austen, Mol. Ind. i, 1883, p. 82 



(no description), pi. 26, fig. 8. [This shell, from Jeypur, differs 



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



Similar to M. 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, columellar margin but 

 little curved, oblique throughout, slightly expanded for some 

 distance, more so at the perforation. 



[" Macrochlamys (Parisuath). 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, especially on the pedicles and back, black ; 

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

Hob. Upper part of Parasnath Hill in "Western Bengal (W. 

 T. B., Stoliczka), Panchet Hill near Raniganj ( W. T. 5.), Manbhum 

 <F. Ball} ; ? Madhopur, Jeypur (Capt. A. B. Melville). 



Teeth in radula 27 . 15 . 1 . 15 . 27 (42 . 1 . 42) in a Parasnath 

 shell ; 38 . 12 . 1 . 12 . 38 (50 . 1 . 50) in one from Manbhum. 

 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 notch near the apex ; the inner 

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