few with an umber tint ; spire subconoid ; suture impressed ; 

 whorls 6, closely or regularly wuuud ; aperture semihuiate, sub- 

 vertical ; peristome thin ; columellar margin subvertical, slightly

8ize : maj. diam. 11 "75, min. 10-0 ; alt. axis o'O mm. 



On Nemotha Mr. J. Wood-Mason collected a number of species 

 of this genus, labelling them from M°, M'-M' ; it would appear 

 thereby he had noticed differences in the animals, and in all 

 probability notes were made of them ; unfortunatjely neither these 

 nor specimens preserved in spirit bearing similar labels have come 

 to hand, thev would have been most valuable. 



No. 1752 B.M. Coll. 



Three specimens in \^ hich the dried-up animal was noticed were 

 put to soak ; unfortunately, when examined, the soft parts had 

 decayed, but out of two the jaw and radula were secured. 



Tlie formula of the I'adula is 



48 . 2 . 12 . 1 . 12 . 2 . 48 

 62 . 1 . 62. 



The jaw has a small median projection. 



Only the jaw of No. 1758 was found. 



The animal (Plate CXXXII. tig. 8) has a very long right shell- 

 lobe, even in the contracted state of the one examined, so that it 

 must be unusually long in life, there is also a narrow much shorter 

 left shell-lobe. The mantle zone is margined with a well-marked 

 black band, the rest of the wall of the branchial chamber is quite 

 plain. The mucous gland at the extremity of the foot is covered 

 by a large upright lobe, bending over in life ; the visceral sac is 

 mottled with white. 



Maceochlamys steiaticostata, n. sp., Nevill MS. (Plate 

 CXXXII. fig. 5.) 



Locality. Silchar, Cachar {J. Wood-Mason). Type, Indian 

 Museum, Calcutta. 



Shell globosely conoid, narrowly umbilicate ; sculpture in- 

 distinct microscopic longitudinal striation, somewhat fiat on the 

 base which is polished, crossed by close irregular folds of growth, 

 costulate in type ; colour pale ochraceous and umber ; spire 

 conoid, high, sides slightly convex, apex rather pointed ; suture 

 rather shallow ; whorls 6, very regularly increasing : aperture 

 semilunate ; peristome thin ; columellar margin oblique, not 

 thickened and scarcely reflected. 



Size : maj. diam. 9'75, min. 9"0 ; alt. axis 5*9 mm. 



There is only one example of this species, and I should hesitate 

 to describe it were it not so very distinct from any I have seen 

 from this part of India, and would be so easily recognizable when 

 found again.
