74. LAND AND FRESHWATER 
Genus Srrata (continued from page 43). 
Srrata? BALLIANA, n. sp. (Nev. MS.). (Plate XV. fig. 2.) 
Loeality. Hills near Ganjam, Madras (V. Bail). 
Shell umbilicate, carinate, conoid; sculpture, transverse rather 
irregular fine ribbing or costulation, with four or five strongly marked 
longitudinal ribs ; colour umber-brown, covered with a strong epider- 
mis ; spire rather high, conic, sides slightly convex; suture im- 
pressed; whorls 5, very conyex; aperture semilunate; peristome 
moderately thickened and slightly reflected near umbilicus. 
Size: major diam. 3°6 mm., alt. axis 2;0 mm. 
O-14 inch », 0°08 inch. 
This shell falls close to S. palmari ia (p. 35, Plate X. fig. 3) in its 
keeled and conoid form; but it is very ae smaller, unbiased, 
and the longitudinal ribbing i is not so high in relief, being finer and 
closer. 
SITALA UvIDA, n. sp. (Plate XIII. fig. 5.) 
Locality. Teria Ghat, south base of Khasi Hills (7. H. G.-A.). 
Shell narrowly umbilicate, globosely conoid; sculpture wavy, 
transverse ribbing, crossed by fine indistinct longitudinal lines, 
which are more distinct on apex, and distant well-marked concen- 
tric ribbing on the base; colour pale sienna-brown ; spire conoid ; 
suture well impressed ; whorls 5, closely wound, convex; aperture 
ovate, oblique; peristome rather thickened, columellar margin 
oblique. 
Size: major diam. 0-11 inch, alt. axis 0°07 inch. 
2°8 mm., e 1-7 mm. 
Also one from the Jatinga valley, North Cachar Hills. 
Somewhat like S. srimant (Plate IX. fig. 7); but the form and 
sculpture distinguish them when the shells are placed side by side, 
wvida being higher in the spire and with much rounder whorls. This 
species, together with the next, should come in after tertcana and 
srimant in the Table given in Part II. page 43. 
I defer the continuation of this synopsis of the species until more 
are figured and described. 
SITALA PLACITA, n.sp. (Plate XIV. fig. 3.) 
Locality. Khasi, one specimen (type); Munipur, one specimen 
(H. H. G.-A.). 
Shell, perforation concealed, globosely conoid ; sculpture, distant 
longitudinal ribbing, on the base far apart and well raised; colour pale 
horny; spire rather high, conic, apex blunt; suture impressed ; 
whorls 43, convex, last well rounded on periphery ; aperture ovate 
or nearly semicircular ; columellar margin suboblique. 
Size : atin diam. 2°8 mm., alt. axis 2°0 mm. 
O-11 Hehe bs 0-08 inch. 
This shell in its form approaches S. srimani (Plate LX. fig. 7), 
but is not so flat on the base.
