TORTFLOSA. 177 



254. Tortulosa congener, SyJces. 



Cataulus congener, Sykes, Journ. JMalac. xii, 1905, p. 57, text-fig. 4. 



Original dfscripiion : — ''Shell elongately pyramidal, rimate, 

 yellow, becoming tinged with red-brown on the earlier whorls, 

 these latter are smooth, while the rest of the shell is closely, finely, 

 longitudinally striate ; suture well impressed ; whorls 7|, convex: 

 umbilical region moderate in size, sculptured as the rest of the 

 shell ; aperture subcircular ; lip white, double, the outer part well 

 reflected and thin at the edge, slightly produced at the right upper 

 margin, the inner part circular and produced ; basal canal small, 

 the carina being whitish. 



"Alt. 16'5, diam. max. (last whorl) 6 mm." 



Hab. Ceylon. 



" Eeserabling in form a dwarf C. aureus, but separable by inter 

 alia the shape of the outer lip and the duplication of the lip, 

 as also by the small basal canal." (Si/Jces.) 



255. Tortulosa connectens, Fulton. 



Cataulus connectens, Fulton, Journ. jMalac. x, 1903, p. 102, pi. 9, 

 flg. 4 ; Sykes, op. cit. xii, 1905, p. 55. 



Original description : — " Shell fusiform, oblong, solid, narrowly 

 perforate, dark reddish-brown ; whorls QJ, obliquely striated, 

 lower slightly convex, earlier whorls almost straight, the last 

 carinated at the base ; aperture circular, pale reddish-brown 

 within; peristome continuous, yellow, thickened and reflexed, 

 an egg-shaped opening to basal canal. Operculum normal. 



"Major diam. (including peristome) Sk, alt. 21 mm." (Fulton.) 



Hah. Ceylon : Watawala ( Collett). 



Stated to be closely allied to hlanfordi, Dohrn, and decorus, 

 Bens., but readily separable from the former by its yellow peri- 

 stome, from the latter by its smaller size and more slender form, 

 and from both by the peristome being more in line with, or under, 

 the whorls. 



Mr. Sykes considers it to be only a local race of hlanfordi with 

 yellow peristome.
