Cryptozoic Fauna of Neio Zealand. 399 



12. Geoplana sulphurea, Fletcher and Hamilton, var. 



Two specimens collected by Mr. Thomas Steel at Albert 

 Park, Auckland, differ from the common New South Wales 

 form only in the presence of minute specks of brown scattered 

 over the yellow ground-colour, between the inner and outer 

 dark brown stripes on the dorsal surface. 



13. Geoplana cosrulea, Moseley, var. 



Mr. Steel also collected at Albert Park, Auckland, three 

 specimens of the blue-tipped variety of this species, indistin- 

 guishable from those found in gardens near Melbourne, and 

 probably introduced. Messrs. Fletcher and Hamilton origi- 

 nally recorded this blue-tipped variety from Sydney. It has 

 never been found in the native bush, so far as I am aware, and 

 appears to have been widely distributed by man's agency. 



14. Geoplana purpurea, sp. n. 



It is perhaps doubtful whether this species ought to be 

 separated from the Australian G. cairulea, from which it 

 differs only in colour. The body when crawling is long and 

 slender, tapering very gradually at each end, with strongly 

 convex dorsal and not very much flattened ventral surface. 

 The ground-colour of the dorsal surface is rather dark reddish 

 purple, interrupted only by a very narrow median band of 

 nearly white. The anterior tip is paler, pinkish. The ventral 

 surface is paler purple, under a lens appearing very finely 

 mottled in two shades. In spirit the peripharyngeal aperture 

 is about central, and the genital at about one third of the 

 distance from it to the posterior extremity. 



I have received three specimens of this worm from Ash- 

 burton, in the South Island, obtained for me by Mr. Fooks 

 and Mr. Mayne. 



15. Rhynchodemus Moseleyi, Fletcher and Hamilton. 



Rhynchodemus Moselerji, Fletcher and Hamilton, Proc. Linn. Soc. 

 N. S. W. vol. ii. 1887, p. 371. 



With this species I identify a number of small specimens 

 of Rhynchodemus collected by Mr. T. Steel at Albert Park, 

 Auckland. It is quite possible that the species has been 

 introduced with plants, and we cannot yet say with certainty 

 that the genus Rhynchodemus is indigenous in New Zealand.
