visible on the back of the whorl in four pale bands, giving that part a 

 furrowed appearance ; and two others on the interrupted part of the 

 peristome, the inner one, which is indeed quite within the aperture, be- 

 ing the largest of all, and the other one small and placed at the angle 

 of the outer lip. Length J inch. 



This pretty little species was discovered under stones among blocks 

 of limestone bordering the desert plain of Dusht-i-be-dowlut, at the 

 western end of the Bolan Pass. It is very closely allied to the Eng- 

 lish species Pupa Juniperi (Gray), having the teeth arranged much in 

 the same manner ; those of the body whorl giving rise externally to the 

 same furrowed or ribbed appearance. It differs however, in having 

 only seven whorls instead of 8 or 9, and in having the largest tooth 

 placed well within the aperture on the middle of the body whorl. 

 8. — Pupa spelcea (Hutton). 



Shell composed of eight convex whorls ; 9J lines in length, of which 

 nearly one half is occupied by the body whorl ; closely and coarsely 

 striated by the lines of increase ; polished, nude, ventricose ; aperture 

 ovato- quadrate ; lips slightly reflected ; subumbilicate ; spire suddenly 

 tapering ; obtuse ; colour white with darker dashes ; the markings 

 however cannot properly be termed colours, since they are in reality 

 only streaks in sculpture, caused by the unequal thickness of the shell, 

 which exhibits alternately an opaque and a semitransparent layer of 

 increase. Pillar lip straight ; the outer one bending suddenly in on 

 the body whorl. Found adhering to the inside of fissures and caves at 

 Dusht-i-be-dowlut, and in the Bolan Pass. 

 9. — Pupa indica (Benson's Mss.). 



P. cylindrica (Hutton), J. A. S. Vol. III. p. 85, No. 6. 



This common Indian species, first described and named by me in 

 1834, runs into three remarkable varieties, differing so much in size 

 and shape that it would not surprise me to find eventually that they 

 are distinct. The name originally bestowed by me has been abandoned 

 in consequence of its being pre-occupied, and Mr. Benson having pro- 

 posed, from the wide range of the species, to call it P. Indica, that 

 name has been adopted. The large variety has 9 to 10 whorls ; is 

 cylindriform and tapers suddenly to an obtuse apex ; colour of living 

 shells pale fuscous or earthy, but generally white ; whorls closely 

 wrinkled by coarse waving lines of increase ; in fresh specimens faintly
