subvar. (?). 

 2 Miisulipatam ; coll. Dr. F. Stoliczka (30, 23i), 



subvar. sindica, nov. 



Long. 32, diam. 21f 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. Karachi Museum. 



subvar. subumbilicata. 



12 Ferozpur; coll. Captain E. 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, Jig. 64, from Cambodia. 

 1 Laos Mns. ; ex Mr. Sowerby [ex c. Lombe Taylor]. 



subvar. 

 1 Penangj 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 mai'ked and characteristic variety, easily dis- 

 tingiiished 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.
