36 LAND AND FRESHWATER 
GuessuLa (RIsHETIA) GAROENSE, n. sp. (Plate CLIX. fig. 15.) 
Locality: South Garo Hills. Type. No. 1595 B.M. (Godwin- 
Austen), 
Shell attenuately turreted, sides flat, thin; sculpture, surface 
very smooth, a few distant transverse shallow engraved lines, 
differing from the usual raised striz; colour pale umber-brown ; 
spire fine ; apex very attenuate, first 4 whorls with same diameter 
(Pl. CLXIV. fig. 5); suture shallow ; whorls 13, sides flatly convex, 
there is but little difference in the diameter at the 9th whorl and 
the last; aperture narrowly ovate; peristome thin, a callous on 
the body whorl; columellar margin oblique, very slight in structure. 
Size: maj. diam. 5-0; total length 27-25 mm. 
In form it is similar to G. baculina, var. evilis of Sikhim; the 
apex is not so attenuate, the whorls are flatter, and the sculpture 
differs considerably. In the Sikhim form there is much raised 
striation, 
Under No. 68, p. 169, of ‘ Nevill’s Hand-list,’ 2 specimens from 
the Garo Hills are recorded under G. pertenuis ; they were presented 
unnamed by me. ‘These have been kindly sent home for comparison 
by Dr. N. Annandale, to whom my best thanks are due; they are 
this species garoense. On this data in the ‘ Hand-list,’ Mr. Gude 
in ‘ Fauna British India’ extends the range of G. pertenws, a Pegu 
species, to the Assam Range; such record ot distribution is valueless. 
Giessuta (RisHETIA) GAROENSE, G.-A, 
Locality. South Jaintia; 4 specimens, No. 3562 (Godwin- Austen). 
Shell attenuately turreted; sculpture, striation very fine and 
close, disappearing in full-grown shells; colour dull umber-brown ; 
spire tapering evenly ; whorls 12. 
Size: maj. diam. 5°5; length 26°75 mm. 
At first sight there is a remarkable similarity between this 
species and G@. pertenuis, Wm. Blanford, of Bassein, but it dis- 
appears under the microscope. The apical whorls are not alike, 
and the aperture differs still more on the columellar margin and@ 
truncation. 
GrussvLa (Risperia) GARoENSE, G.-A., small var. (Plate CLIX. 
Hebd.) 
Locality. Naraindhur, Cachar; 11 specimens. Type. No. 1657 
(F. Ede), 
This measures 20°5 mm. in length and 4°5 mm. in maj. diam. 
It is of a darker umber than typical garoense, and has the very 
smooth surface of that shell; 12 whorls, sides slightly more 
convex; apex very fine, first 4 whorls hardly increase at all 
(Pl. CLXIV. fig. 6). 
lam fortunate in having specimens in spirit of a small elongate 
many-whorled species from Silchar, Cachar, sent me by Mr. F. Ede.
