Locality. — Near Invercargill. Two specimens, collected 

 by G. Howes, Esq. (one specimen on the 17th April, 1898, 

 five miles from Invercargill). 



Geoplana graffii, var. ocellata, nov. var. 



Body at rest (in life) very broad, flat, and thin ; about 

 22mm. long by 95mm. broad; tapering gradually to the 

 horse-shoe-shaped anterior extremity and to a sharp point 

 behind ; with a slightly developed median dorsal ridge. When 

 crawling about 31 mm. long ; strongly convex and rounded 

 above, flattened beneath. Eyes as usual, in two crowded 

 lateral patches, and continued in single series round the horse- 

 shoe-shaped anterior end. Dorsal surface in life dark ma- 

 hogany-brown, with irregularly scattered paler blotches of 

 rounded shape. The margins of the body are occupied by a 

 very narrow pale band, merging dorsalwards in a row of very 

 irregular small patches of the same tint, some of which are 

 •quite isolated. In the mid-dorsal line is a single row of the 

 pale rounded blotches at irregular and wide intervals, each 

 with a conspicuous central " eye " of a pale-green, nearly 

 white, colour. (The spirit specimen shows the pale blotches for 

 :some distance on either side of the mid-dorsal line to be less 

 distinctly " eyed.") The entire dorsal surface, except about 

 the middle line, is dusted with minute specks of very pale 

 iridescent green, showing a tendency to arrangement in longi- 

 tudinal rows. The ventral surface in life was pale-brown, 

 pretty uniformly but rather sparsely speckled with small 

 rounded spots of dark-brown, absent for a narrow space sub- 

 marginally but present in the middle. The pale ground- 

 colour greatly preponderates, and the dark spots are widely 

 separated from one another. Margins dusted with minute 

 specks of the pale iridescent green. 



In spirit the body is strongly convex above, flattened be- 

 low, with narrow, slightly prominent margins ; about 23 mm. 

 long and 5 mm. broad, with the genital aperture (?) mm. and 

 the peripharyngeal aperture 9-5 mm. from the posterior ex- 

 tremity. 



This variety apparently comes near to Geoplana gelatinosa. 

 The single specimen was sent to Dr. Benham by Mrs. Mason, 

 who said it was luminous. 



Locality. — Paradise (Lake Wakatipu). 



Geoplana graffii, var. wharekauriensis, nov. var. 



Body in life much flattened ; when at rest may be 

 triangular in section, flat beneath, and with a rather pro- 

 minent mid-dorsal ridge ; shape altogether like G. graffii. 

 In life the colour of the dorsal surface is mahogany-brown, 

 with a narrow paler reddish-brown stripe down the middle,
