MOI.LrSCA OF INDIA. 43 



Jadukamia, siibgeii. nov. 



Shell small, short, solid, regularly ribbed, almost costulate ; 

 spire elongately conoid: apex bluntly pyramidal, very rounded; 

 columollar margin short, concave, and abruptly truncate. 



Glesstjla (Jadukamia) abnormis, n. sp. (Plate CLX. fig. 22.) 

 No. 1034, 06. 1-1. 



Locality. Khasi Hills {Godwin-Awtten). 



Shell ovate ; sculpture : close, regular, strong ribbing, almost 

 costulate ; colour ochraceous, shiny ; spire elongately conoid, apes 

 bluntly pyramidal : suture well impressed ; whorls 4, sides flat, 

 the first large ; aperture ovate, not fully developed ; columellar 

 margin vertical. 



Size: maj. diam. 4'0 ; alt. axis 7'10 mm. 



This shell, together with two specimens of O. crasdlahris, was 

 sent bv me to Wm. Blanford many years ago, as recorded in his 

 catalogue ; its peculiar form was not noticed. I then put it on one 

 side under the impression it was an accidental variety of some 

 species. When going through the collection of Olessulce collected 

 by me in the Dafla Hills, Assam, I came on another specimen 

 among some found on the Shengorh Peak, almost identical with 

 the Khasi Hill shell. When one considers the enormous areas — in 

 Assam, for instance — asyetunvisited by a conchologist, and compares 

 them with the small scattered sj)ots, miles apart, where often only a 

 hurried search was possible, on one day in the year, there must 

 be many a species 3-et to be discovered. More extensive diligent 

 search in both the Khasi and Dafla Hills would lead, doubtless, 

 to more specimens of this curious shell being found. 



Glessula (Jadukamia) adnokmis, n. sp. (Plate CLX. fig. 23.) 



Locnlity. Shengorh Peak, Dafla Hills. No. 3370 {Godwin- Austen). 



Shell elongately ovate ; sculpture fine, very regular raised 

 ribbing ; colour pale ochraceous ; whorls 4, the first very ample ; 

 aperture ovate ; columellar margin nearly vertical. 



Size: maj. diam. 4-0; alt. axis 7"20 mm. 



This Glessula is so distinct in shell character from all as yet 

 known that I am induced to put it in a new subgenus, which I 

 describe above.
