18 LAND AND FRESHWATER 



in size, I. «., increasing very gradually; aperture narrowly oval; 

 columellar margin very slightly convex. 



[Size: niaj. diain. 4-0; alt. axis 11-20 mm. 



This is more elongate than O. crassula, but similar in coloration 

 and sculpture. It is certainly more than a variety of the Darjiling 

 shell. 



Ill Wm. Blaiiford's collection is a single specimen, which I refer 

 to this species, found by him on the Chola range at 11,U00 ft.

Locality. Earbichu, Sikhira. Type. (No. 3592 B.M.) Richila 

 Peak, var. (No. 555 B.M.) ( W. Robert). 



Shell coiiicall)- turreted and elongate, solid, smooth, and shining: 

 sculj)ture : very regular sharp striation; colour dark rich ochre, 

 a paler margin to the peristome; spire high, sides slightly convex, 

 apex blunt ; suture im])ressed ; whorls 74, flatly convex, the 

 last tumid; aperture oval; peristome well thickened; columellar 

 margin strong, curved, notch at base deep. 



Size : maj. diam. 9-25 ; length 21-25 mm. 



Animal (Plate CLXV. fig. 2 a). With short foot, the sole of 

 which has a central groove each side close])- segmented. 



The buccal mass (Plate CLXV. fig. 2 b) is globose and small 

 with a very strong retractor muscle ; the salivary gland is in a 

 single bilobed mass, one side long and pointed. 



In the generative organs (Plate CLXV. fig. 2 c) the hermaphro- 

 dite duct is conspicuous by its size, is very long and strongly and 

 closely convoluted. The albumen gland is very globose. The 

 uterus and closely convoluted oviduct short. The penis is a folded 

 sheath, and what I take to represent the flagelhim is a flattened 

 mass, straight on one side, having a serrate edge on the other, 

 consisting of a short terminal and ten longer notches, verj' cha- 

 racteristic and unusual in form. A similar flagelhim is met with 

 in orophila, Bs. , as figured by Professor Semj)er (Reis. Arehipel. 

 187.'{, p. 133, Taf. xii. figs. 14-16, under Cionclla) there is one 

 terminal and 30 notches, givii'g it a feather-like form. The vas 

 deferens joins the penis close to this at the distal end. 



The spermatheca is oblong, rather short, on a short thick 

 base. 



Glessula ocheacea, G.-A., var.

Is larger and a much darker ochre than the type.
