SYKES : COLLECTION OF LAND AND FRESH WATER SHELLS. 6 1 



that the name pefi'versits, which I should otherwise have used for this 

 shell, is to be restricted to forms found in Celebes, Java and Borneo. 



Hypselostoma hungerfordianum, MlldiY. 



A good series of this interesting shell. 



Boysidia kelantanense, n.sp. pi. iii, f\g. 7. 



Shell umbilicate, obliquely striated, chestnut brown. Whorls 

 4^-5, very convex and suture deep, apex blunt, the last whorl some- 

 what distorted, obscurely angulated at the periphery. Aperture 

 rounded, with a sinus at the upper corner of the outer lip ; lip well 

 reflected, not solute from the last whorl. Parietal lamella strong, 3 

 other well marked teeth inside the outer lip, and one each side of 

 the lamella. 



Alt. 3 ; diam. max. 2 millim. 



Belongs to the group of B. hoptt(jpri, Mlldff., from Java, and B. 

 palmira, Stol., from Penang ; compared with the latter the last whorl 

 is more distorted and gibbous and the relative proportions of height 

 and breadth differ, the present species being also much larger. 



Rhodina (?) mirabilis, Sykes. Pi. iii, liy. 2. 

 lihodina (?) mirahilu, Sykes : Ante, p. 22. 



Subulina oetona, ciiemn. 



Clausilia filieostata, stoi. 



Clausilia kelantanense, Syk-es. PL iii, fig. i. 

 Clausilia (PseuiJonenia) lielantanese (err. typ.), Sykes : Ante, p. 22. 



Cyelophopus saturnus, Pfeiffei-. 



Cyelophorus borneensis, .Metcalie. 



Lagoehilus townsendi, Crosse. 



Opisthoporus dautzenbergi Sykes. Pi iii, figs. 5, 6. 

 Opidlioj^xmis daiitzenheiuji, Sykes : Ante, p. 23. 



Opisthoporus tener, Menke. 



Compared with specimens of this species from Annam (coll. 

 Fruhstorfer), I can trace but little distinction except size, one of the 

 adult Kelantan shells, for example, only measuring diam. max. 13-5 

 millim. The tube is also slightly more parallel to the suture. 



Platyraphe chrysalis, Sykes. Pi. iii, i.i;!-. 3, 4 



Plafyrajiilie clirysaUs, Sykes : Ante, p. 23.
