I know it has only been found at Sispara on the Western edge of 

 the Nilgiri plateau, whilst JV". apicata is found on the Northern and 

 Eastern portion of the hills. 



The present shell may be destinguished from most of its allies, 

 such as N. hypliasma, Pfr., by its want of marked sculpture, its 

 straight sides and high spire. 



14. Nanina (Ariophanta) immerita, sp. nov. 



Testa sinistrorsa, anguste umbilicata, depressa, sublenticular is, fulvo- 

 cornea, tenuis, oblique striata ; spira parum elevata, conoideo-convexa ; 

 apice perobtuso ; sutura vix impressa. Anfr. 4^- convexiusculi, ultimus 

 magnus, acute carinatus, carina antice obtusiori, subtus tumidiori, nitidula. 

 Apertura obliqua sub-securiformis ; peristoma tenue, rectum, margine 

 columellari sub-verticali, reflexo. Diam. maj. 25, min. 21, axis 14 mm. 

 Apertura 13 mill, longa, 11 lata. 



Hab. " South Canara" (B e d d o m e). 



This species approaches JV. interrupta, B s. (JV. Himalayana, L e a), 

 but has the sculpture finer and not decussated. I have only seen 

 two specimens one of which is quite young, and it is possible that 

 the one above described is also immature, but there appears no doubt 

 that the form is undescribed. The specimen having been returned 

 to Major Beddome, I am unable to figure it at present. 



15. Helix (Plectopylis) macromphalus, sp. nov. PL 



III, fig. 14. 



Testa sinistrorsa, late umbilicata, depressa, discoidea, tenuiuscula, pal- 

 lido-cornea, superne plicis arcuatis obliquis incrementi et liris spiralibus 

 decussata, ad periplieriam et subtus fere Icevis, striatula : striis nonnullis 

 spiralibus circa umbilicum aliquando distinguendis ; spira plana ; apice vix 

 emergente ; sutura leviter impressa. Anfr. 4% — b^planulati, arete voluti ; 

 ultimus vix latior, supra periplieriam sub-angulatus, ad latus atque subtus 

 convexus, antice leviter descendens. Apertura irregulariter lunaris, 

 superne compressa, diagonalis ; peristoma albido-labiatum, parum incras- 

 satum, reflexiusculum, marginibus convergentibus, callo tenui junctis, 

 externo supra periplieriam arcuato. JPlicatio interna per similis* ei He-
