Helix (^gista) pudica, n. sp. (Plate 11. figs. 7, 7 a.) 



Shell depressedly conoid, subangulately keeled, narrowly umbili- 

 cated, hidden by the columellar reflection ; sculpture, a slightly 

 roughened or shagreen-like surface ; colour pale ochraceous, with a 

 snowy-white peristome ; spire flatly conoid, low ; apex rounded ; 

 suture shallow ; whorls 4, sides flat, a shallow depression near the 

 periphery ; aperture semi-lunate ; peristome reflected on outer margin 

 and thickening towards the columellar margin, which is oblique. 



Size: maj. diam. 20*0, min. 15*8 ; alt. axis 7'75 millim. 



Had. Labuan (Sir H. Low, in coll. Dr. Hungerford). 



Helix (jEgista) grumultjs, n. sp. (Plate V. flg. 2.) 



Shell depressedly conoid, keeled, widely umbilicated ; sculpture, a 

 rough epidermis covered with small spots in relief; the periphery set 

 with regular, short, thick-based hairs; colour ochraceous; spire flatly 

 pyramidal ; side slightly convex ; apex rounded ; suture shallow ; 

 whorls 5, sides flatly convex ; aperture semi-lunate ; peristome 

 slightly reflected ; columellar margin subvertical. 



Size : maj. diam. 8'5, min. 7'8 ; alt. axis 3*5 millim. 



Hab. Borneo (in spirit), exact locajity unknown {A. Everett). 



This is the nearest approach to the Helix huttoni group of India 

 that I have seen from this island ; the odontophore is like that of 

 Helix ; the mantle-margin is simple. 



Helix (Plectotropis) winteriana.

Hab. Mulu Mountains (Boxall, in coll. Dr. Hungerford). 



This is allied to H. quadrivolvis, v. Martens, which has a narrow
