new Species o/* Cyclophorus. 507 



inoderately liigli, sides slightly convex, apex sharp ; suture 

 shallow; whorls o, sidivs convex, the last somewhat keeled ; 

 aperture circular, oblique; peristome white, not thickened, 

 slightly reflected. 



6Vz^, type: niaj.diam.48'7o,min. 39 0; alt.axis22-2.5 mm. 

 largest: „ 500, „ 42-0; „ 23-0 „ 



Loc. Naga Hills {Dokerty) ; Maokokchung, Naga Hills 

 [Miiriipratt) . 



In the young shell the longitudinal striae are very sharp 

 and distinct, quite Urate in appearance ; this character sepa- 

 rates it from the other species of Ci/clophorus from these hills. 



Cyclophorus nagaensis^ sp. n. 



Shell umbilicated, turbinate, not keeled; sculpture, lines of 

 growth only, without any spiral lines being visible. Colour 

 grey- brown, more ochraceous below, when wetted ota madder- 

 brown colour ; a white line on the periphery, bounded by a 

 broad very dark band, shaded off below ; the tliird whorl is 

 crossed by narrow wavy white lines ; in the next growth 

 these lines arc wider apart and zigzag in outline ; the next 

 and final growth is ])lain. Spire depressedly conoid, apex 

 subacute ; suture shallow ; whorls 5, rounded ; aperture sub- 

 vertical, large, circular, grey within ; peristome not much 

 thickened, scarcely reflected, bright orange-red. 



Size : maj. diam. 45*0, niin. 36"0 ; alt. axis 21*0 mm. 



Loc. Naga Hills, near Khonoma and Kigwema, 5000-6000 

 feet {Dohertt/) ; Maokokchung [Muspratt). 



The form of this species is very similar to G. Pearsoni, but 

 the red of the lip is more intense than in shells from the 

 typical locality; its very smooth surface also distinguishes it. 



Cyclophorus pcBciloneuruSj sp. n. 



.S7^e// umbilicated, turbinate, keeled ; sculpture, apex smooth 

 and shining; five distinct Urate ribs run contiguous to the 

 suture on the lower margin of the whorls, commencing with 

 the third whorl ; these have two finer thread-like ribs between 

 them, and similar fine liration is continued above and on the 

 lower surface of the sliell, crossed by strong lines of growth 

 on the epidermis. Colour umber-brown, marbled with madder- 

 brown, given ofi" from a few strong spots of this colour next 

 the suture ; the peripheral rib is dashed with white at 

 intervals. Spire conoid, sides flat, apex sharp ; suture shallow; 

 whorls 5, subconvex, the last sharply keeled, forming a strong 

 rib; aperture oblique-ovate, ample on the outer margin, grey
