V. striata, Dujardin. 

 (Sarille Kent, Man. Inf., p. 684, pi. xxxiv., figs. 15-19; pi. xlix., fig. 29.) 

 On Algas in Wellington Harbour, 1883, but not seen since. 



V. aperta, De Fromentel. 

 (Saville Kent, Man. Inf., p. 680, pi. xlix., fig. 17.) 

 Examples closely resembling this species were obtained in 

 1884 from the pond in Newtown Park. The body, however, 

 was fully twice as long as wide, and was more constricted 

 beneath the peristome border than shown in Saville Kent's 

 figure. 



V. dblonga. 



V. zealandica.
