216 Transactiom. — Zoology. 



V. longifilum, Saville Kent. 

 (Saville Kent, Man. Inf., p. 677, pi. xxiv., fig. 30; pi. xlix., fig. 10.) 

 Wellington Eeservoir, September to February. Collected in 

 1884-5. Common. 



V. campanula, Ehrenberg. 

 (Saville Kent, Man. Inf., p. 678, pi. xxxiv., fig. 36; pi. xlix., fig. 12.) 

 Wellington Eeservoir, with the last-mentioned species, and 

 equally common. 



V. cratera, Saville Kent. 

 (Saville Kent, Man. Inf., p. 679, pi. xxxiv., fig. 22 ; pi. xlix., fig. 14.) 

 Some specimens so closely resembling this species were 

 obtained from water brought from the Wainuiomata, that I am 

 compelled to refer them to it, although I was quite unable to 

 detect any appearance of the " frill-like aspect presented by the 

 peristome border," mentioned by Saville Kent. The border 

 appeared to me to be perfectly whole. 



V. citrina, Ehrenberg. 

 (Saville Kent, Man. Inf., p. 678, pi. xxxv., fig. 9 ; pi. 49, fig. 13.) 

 On Azolla rubra, from ditch in Evans Bay. 



V. zealandica, n. s. 



Body attenuate, from two to three times as long as the 

 greatest breadth, tapering downwards, considerably constricted 

 below the peristome, then swelling for rather more than half 

 the length, when it again becomes constricted ; then a nearly 

 circular swelling, giving the posterior end an unusually blunt 

 appearance. Apparently striated perpendicularly, but of this I 

 am not certain, as sometimes the striations were seen, while at 

 others they disappeared, as though at the will of the animal. 

 Pedicel slight, four times the length of the body. 



Pond in Newtown Park. 



V. elongata, De Fromentel. 

 (Saville Kent, Man. Inf., p. 686, pi. xxxv., fig. 25 ; pi. xlix., fig. 42.) 

 Specimens were taken in November, 1884, from the pond in 



the Botanic Garden, attached to the leaves of the water lily. 



The pedicel, however, was much shorter than mentioned by 



Saville Kent, being never more than three times the total 



length of the body. 



V. patellina, Miiller. 

 (Saville Kent, Man. Inf., p. 679, pi. xxxiv., fig. 28; pi. xlix., fig. 16.) 

 Newtown Park and Wainuiomata. 



V. nebulifera, Ehrenberg. 

 (Saville Kent, Man. Inf., p. 673, pi. xxxiv., fig. 20 ; pi. xlix., fig. 1.) 

 Ditch in Evans Bay, on Azolla ; Botanic Garden pond, on 

 grass.
