Q8 PALUDINIDA. 
subvar. (?). 
2 Masulipatam; coll. Dr. F. Stoliczka (30, 234). 
subvar. sindica, nov. 
Long. 32, diam. 213 mil.; not decollate, 6 whorls, almost 
colourless, though apparently taken alive as the opercula are 
still present! Similar specimens were found by Mr. F. Fedden 
in Katniawar. 
10 Sind ; ex c. Karéchf Museum. 
subvar. subumbilicata. 
12 Ferozpur; coll. Captain R, C. Temple. 
Columella straighter than usual, only slightly edged with 
black ; distinctly openly rimate, almost umbilicate; slightly more 
convex whorls, the last one almost perfectly rounded ; belt at 
periphery less distinct than in typical form, substance of shell 
a trifle thicker and less brightly coloured. 
var. fulva. 
Paludina fulva, Reeve, Icon. 1863, fig. 64, from Cambodia. 
1 Laos Mns.; ex Mr. Sowerby [ex c. Lombe Taylor]. 
subvar. 
1 Penang; ex c. India House Museum (c. Cantor). 
Last whorl a trifle less rounded than in the preceding form, 
sculpture less distinct, spire more produced; altogether it is 
scarcely distinguishable from some Indian varieties! In neither 
of these var. fulva is there any trace of a white belt at the 
periphery. 
var. assamensis, nov. 
This is a well marked and characteristic variety, easily dis- 
tinguished from all the preceding forms by the turreted and 
remarkably produced spire, the cylindrical instead of convex 
whorls; the deep, uniform green colour, the last whorl and 
aperture much smaller and more contracted in proportion, the 
latter less everted; periphery subangulate, with the belt ob- 
solete; scarcely rimate; peristome black.
