196 ZONITIDiE. 



projecting from the side ; much broader than Girasia hooJcet'i,. 

 covered with an olive epidermis showing lines of growth. 



Major diam. about 22, min. about l-l- mm. 



Aunnal ochre-colour, prettily mottled and dotted with a darker 

 shade of the same ; the mantle covers nearly the whole shell ; a 

 narrow white line commencing near the posterior margin of the 

 slit disclosing the shell extends rouiid towards the respiratory 

 orifice on the right-hand side, and in front another line curves 

 round to the left anterior side. Length about 3 inches.

Shell oval, fairly solid, smooth, shining, colour pale olive ; apex 

 small, not projecting, very closely wound ; whorls about 1| ; 

 aperture ovate, occupying nearl}' the whole shell, only about a 

 ninth being taken up by the reflected whorl, columellar margin 

 evenly sinuate. 



Major diam. 11, min. 6^, height about 3 mm. 



Hah. North Cachar Hills : Kohima, Dunsiri Valley. 



Animal dark umber to pinkish grey, much speclded throughout, 

 and with black lines on the side of the foot. Dorsal lobe ample, 

 extending round to the left posterior side ; right dorsal lobe rather 

 small. The right sliell-lobe is expanded over the apex, but is 

 hardly connected behind ; the left sliell-lobe is narrow and laps 

 over the peristome, but does not join the other lobe. The 

 posterior margin and apex of the shell rests in a V-sliaped de- 

 pression of the ridge of the foot, and the hinder part of the foot 

 thence to the mucous gland is very short. 



The teeth of the radula are thus arranged : 40 . 15 . 1 . 1.3 . 40 

 (55 . 1 . 55). The inner laterals (admedians) have a well-formed 

 cusp on the outer basal side ; the outer laterals are very pointed 

 and curved, with the outer cusp quite basal.

Shell close to A. cacharica, but considerably stronger and the 

 apex thicker. The columellar margin of the peristome is much 

 incurved. 



Major diam. 14|-, min. 9, height 4| mm. A smaller specimen 

 measures 9 mm. in major diameter.

This may be the same as the last, but the shell shows slight 

 differences. The animal is not known.
