MACROCnLAMYS. 89- 



well marked, fine, regular, longitudiual striatiou, showing even on 

 the lower side ; it is a far stronger striation than is seen in 

 M. sailiilaensis ; colour pale ashy brown ; spire flatly conoid ; 

 suture impressed. Whorls 5, not fully grown ; aperture widely 

 lunate, subvert ical ; peristome very tliin ; columellar margin sub- 

 vertical, with slight reflection. 



Size: maj. diam. 9-0, alt. axis "Ah mm. 



The coil of tlie spire differs from that of M. sathilaensis. 



Locality, liichila Peak, iihutan frontier. 



Animal. Pale-coloured throughout, with black head and the 

 extremity of the foot tinged very slightly darker towards the tip 

 of the overhanging lobe. Jjoth the sliell-lobes are very long, 

 particularly the right, longer than in any spirit-specimen I have 

 ever handled. The right dorsal lobe is small, the left in two 

 parts. The lobe over the mucous gland is not very pointed. The 

 visceral sac is umber-brown, sparsely mottled in front v\'ith black, 

 and a long black streak next the renal organ. 



Generative organs. The coiled caecum is exactly like tliat of the 

 typical species. The kale-sac is long. The spermatheca long. 

 The radula is like that of allied species in every way (only the 

 central tooth and admedians seen) : -f- . 2 . 10 . 1 . 10 . 2 . -f ]

Shell perforate, depressed, smooth, polished, obsoletely striated, 

 moderately thin, yellowish to brownish tawny ; spire very low, 

 sometimes almost Hat, suture slightly impressed ; whorls 5, convex 

 above, the last rather broad, rounded at the periphery, moderately 

 convex beneath ; aperture broadly lunate, almost vertical ; peri- 

 stome acute, straight, basal portion sometimes slightly thickens and 

 white inside, columellar margin curved, slightly reflected above. 



Major diam. 26, min. 21, lieight 12 mm. 



Ha1>. Sikhim, 4000-7000'. Not rare about Darjiling. 



This shell may be known by its smoothness, its few whorls, and 

 its broad last whorl. The animal has not been described. 



a^. Conoidly depressed, rugose, transverse (hut no longitudinal) 

 sculpture.
