120 LAND AND FRESHWATER 



figure in the ' Novitates' shows a very much less oblique mouth 

 than is found in Maerochlami/s ? unjnnei. Now, I have another 

 species from Mari, which agrees admirably with Martens's description 

 in these respects and which resembles Jacquemont's figure also, 

 but it wants the red band round the periphery shown in PfeifFer's 

 figure. It is just possible that two species are included by Martens. 

 The true N. jacquemonti is probably a Bensonia." 



Jacquemont does not seem to have got further west in the Punjab 

 than Jhelum, and from that town he passed through Mirpur, Kotli, 

 and Poonch, which he spells Prountche (and not incorrectly, for it is 

 thus pronounced by the Kashmiri lower oi'ders), to the Pir Panjal. 



Subgenus Hatjghtonia, nov. 



Animal with a short foot behind, not divided below ; mucous 

 gland large and open, no overhanging lobe. A mere indication of 

 a right shell-lobe, but none of a left. Anterior left dorsal lobe 

 distinctly separate from the posterior one. Male organ simple, 

 bent on itself, kalk-sac extremely small and globose. Amatorial 

 organ very long, much convoluted. Spermatheca long pear-shaped. 

 Jaw with a concave plain edge. Central teeth numerous, with very 

 reduced cusps on the outer side ; laterals bicuspid. 



Sculpture of shell sharply chiselled longitudinal strise.

The generic position of this the largest of the Andaman land- 

 shells has long remained a point to be cleared up, and I am glad to 

 be at last enabled to give a description of its anatomy, and show 

 to what extent it differs from the larger forms of Ceylon and Penin- 

 sular India on one side, and those of Tenasserim and the Malay 

 Peninsula on the other. 



In 1882 I published a figure of the animal taken from a drawing 

 made under Perd. Stoliczka's superintendence. I then Avrote : 

 "Nevill's Hand-list, p. 46 (1878), places it in the subgenus Bhgsota,
