2 3:0 mm., a 2:6 mm. 
KALIELLA BARRAKPORENSIS, Pfr. (Plate I. fig. 2.) 
Locality. Barisal, forty miles above, near the river Megna, Lower 
Bengal (G.-A.). 
Shell pyramidal, somewhat depressed, base flat ; sculpture rather 
close, fine costulation, each rib distinct, the spiral sculpture on the 
base like that of Mussoorie specimens (Plate I. fig. 36); colour 
horny brown; spire moderately high, broadly conic, sides very 
slightly convex; suture shallow; whorls 5, sides flatly convex ; 
aperture quadrate ; peristome thin, columellar margin subvertical. 
Size: major diam. 0°13 inch, alt. axis 0-09 inch. 
= 3°3 mm., Fe 2°3 mm. 
In a paper entitled “‘ Notes on the Land and Freshwater Shells 
of Kashmir &c.” (J. A. S. B. 1878, p. 142), Mr. W. Theobald remarks 
that the specific name of this shell is badly chosen, this being a hill- 
species (not found on the plains, unless transported on plants). I 
found it very abundant in the above locality in the bamboo-clumps. 
KALIELLA BARRAKPORENSIS, Pfr., = sivalensis, Hutton, var. (Plate I. 
figs. 3, 3a, 36, and Plate II. fig. 1.) 
Locality. Mussoorie, N.W. Himalaya, about 7000 feet (G‘-A.). 
Shell scarcely perforate, conoid, base flat; sculpture distinct, fine 
transverse ribbing, close set, touching, the spiral striation on the base 
regular and wide apart, 4 to 5 lines =-005 inch (Plate I. fig. 3 6); 
colour pale brown; spire high, pyramidal, sides convex: suture 
shallow ; whorls 7, flat; aperture semilunar; peristome thin, re- 
flected on columellar margin, which is perpendicular. 
Size: major diam, 0-14 inch, alt. axis 0°10 inch.

Benson, in ‘Descriptions of new Helicide contained in the Darji- 
ling Collections of Messrs. W.T. and H. F. Blanford” (A. & M.N. H., 
Apr. 1859), writes :—“Two bleached and broken specimens of a 
small shell allied to H. fastigiata, Hutton, from the Western Hima- 
laya, were found by Mr. W. T. Blanford at Pankabari and in the 
Rungun valley, at elevations of 1000 and 4000 feet. They cannot 
be distinguished from Pfeiffer’s H. barrakporensis, of which speci- 
mens were sent to me by the late Dr. J. F. Bacon from Titalya, 
on the border of the Sikkim Terai, before the shell was seen by 
Dr. Pfeiffer ; others were more recently taken by Capt. Hutton in 
the Dhoon valley, below Landour, and were transmitted to me by 
him under the MS. name of sivalensis, H. ..... The occurrence of 
* In all descriptions the most reliable measurement is that of the major 
diameter ; not so that of the height, for it is often doubtful Aow it has been taken. 
Tn this and the following descriptions the height of the shell is taken from the 
lowest portion of the body-whorl at the columnar margin to the apex; this I 
have found much easier to take than the vertical distance from the lowest edge 
of the aperture to the apex. It is simple enough with the ordinary measuring 
instruments when dealing with solid strong shells, but very dangerous with 
small fragile forms,
