sharply. It appears to be characteristic of the Invercargill 

 bush. 



Locality. — Invercargill. Several specimens ; coll., George 

 Howes, Esq. 



Geoplana graffii, var. dorso-marmorata, nov. var. 



Body at rest (in life) flattened or concave below, strongly 

 convex above, somewhat triangular in section. Eyes numer- 

 ous. Dorsal surface in life pale yellowish-brown, irregularly 

 marbled with much darker brown, except for narrow median 

 and supramarginal bands of the ground-colour. Ventral 

 surface pale yellowish-brown, thickly peppered with small 

 specks of darker brown, except for narrow marginal bands 

 where the dark specks are absent ; with an indication pos- 

 teriorly of a narrow median band free from specks. 



In spirit the body is slightly concave below, convex above, 

 with slightly prominent narrow margins ; about 24 mm. long 

 by 4-5 mm. broad, with the genital aperture 8 mm. and the 

 peripharyngeal aperture 12 mm. from the posterior extremity. 



Locality. — The Nuggets (between Otago Harbour and the 

 Bluft). One specimen, collected by Dr. Benham. 



Geoplana graffii, var. clintonensis, var. nov. 



My notes on the living specimens merely state that they 

 are very similar to G. graffii. The two spirit specimens are 

 of the usual form, but the peripharyngeal aperture is well 

 behind the middle of the body. Length of specimen in spirit, 

 23 mm.; breadth, 3 - 5 mm. ; genital aperture about 6 mm. 

 and peripharyngeal aperture about 9 mm. from the posterior 

 extremity. 



The variety is characterized especially by the well-defined 

 character of the pale median dorsal and supramarginal bands. 

 The pale median band has no included stripes and little or no 

 mottling. The supramarginal pale stripes are mottled, like 

 the ventral surface, with a darker tint. The dark ground- 

 colour of the dorsal surface forms two broad bands, in which 

 the pigment is intensified at the edges, and which are finely 

 mottled with the paler shade. The colours of the dorsal 

 surface in spirit are dirty-yellow and dark-grey. The ventral 

 surface is dull-yellow in spirit, finely and uniformly mottled 

 all over with light-grey. There is no pale median ventral 

 band. Eyes as usual in the genus. 



Locality. — Near Mr. Garvey's house, Clinton Valley, head 

 of Lake Te Anau. January, 1900. Two specimens. 



Geoplana graffii, var. angusta, var. nov. 



I have received this variety from several localities in the 

 South Island, and were it not for the occurrence of inter-
