ZONITID.^. 



Size : maj. diani. 10-0, min. S-2 : alt. axis 4-0 mm. 



Locality. Cherra Poonjee and in the valley to the east\vard. 



This shell was also found at Jawai, in the Jaintia Hills. I have 

 named it after Sir Joseph Hooker, who describes so well in his 

 • Himalayan Journals ' the deep valle}^ under Cherra Poonjee.]

Shell subobtectly perforate, depressed, almost lenticular, thin, 

 translucent, yellowisli horny, with dull waxy lustre, concentrically 

 and subpapillosely striated aboAe and below, plicate near the 

 peripherv ; spire low, conoidal, suture very slightly impressed ; 

 whorls oh, almost flat above, the last much broader, angulate and

oblique and gradually disappearing on both upper and lower 

 surface away from the outer edge ; aperture oblique, roundly 

 lunate ; peristome thin, basal margin arcuate, columellar curved, 

 vertical and reflected above. 



Major diam. 22^, min. 194, height 10 mm. 



liah. Satunga, A^. Cachar Hills, on limestone rocks {Godwin- 

 Aiisten). 



[Animal pale brown, mottled very evenly with umber over the 

 head and sides, a distinct line of darker colour down the centre 

 of the back ; moderately long gland at extremity of foot, \\liich is 

 rather truncate. Two parallel lines run from mantle to the oral 

 tentacles, about 1^ inch in length. 



I obtained a large number of this species alive ; no reference is 

 made to the presence of shell-lobes in my note-book, in which 

 there is, besides, a pencil sketch of the animal's head as far back 

 as the dorsal lobe. It is therefore very doubtful if it should be 

 ])laced in this genus.]
