marginal and median bands. The pale submarginal and 

 supramarginal bands are continuous with one another and 

 form an uninterrupted pale marginal band (as is also the case 

 in the Christchurch types, in which I have omitted to men- 

 tion the pale submarginal bands, and have not laid suffi- 

 cient stress upon the minutely dark-speckled appearance 

 of the ventral surface which distinguishes this form from 

 G. moseleyi). 



The largest of the five spirit specimens which I preserved 

 measures now 34 mm. in length by 8 mm. in breadth, with 

 the genital aperture 95 mm. and the peripharyngeal aperture 

 15-5 mm. from the posterior extremity. 



Toitoi, Southland. — Coll., Miss J. G. Eich. A number 

 of fine broad specimens, attaining a large size — up to 42 mm. 

 by 8 mm. in spirit — mostly with a strong tendency to sup- 

 pression of the pale longitudinal bands on both surfaces. 



Peel Forest.— March, 1898. Coll., W. W. Smith, Esq. 

 Two specimens, much like the typical G. graffii in shape of 

 body, and one of them having the pale-brown supramarginal 

 bands fairly well defined. My notes on the living animal 

 say, " Dorsal surface dark-brown, with narrow median longi- 

 tudinal band of paler brown and paler brown lateral margins, 

 with small pale longitudinal dashes of whitish or iridescent 

 blue all over it. Ventral surface with no bands, but finely, 

 mottled with pale- and dark-brown. Shape as in G. graffii." 

 The colouration of these specimens approaches nearly to that 

 of G. graffii, var. angusta and var. somersii. 



Geoplana graffii, var. castanea, nov. var. 



Shape and size in life as in G. graffii ; dorsal surface of a 

 warm chestnut-colour, with a narrow median band and not 

 very well-defined supramarginal bands of pale yellowish- 

 brown ; speckled, especially in the darker parts, with minute 

 spots of pale iridescent green or bluish, which are also very 

 abundant just on the margin of the body ; ventral surface 

 nearly white, abundantly but minutely speckled with pale- 

 brown dots, which are almost absent in the middle line, 

 leaving a median whitish band ; anterior tip brown. Eyes 

 very numerous. In spirit the body is rather broad, about 

 24 mm. in length by 6 mm. in greatest breadth ; the genital 

 aperture about 5 mm. and the peripharyngeal aperture about 

 10 mm. from the posterior extremity ; convex above, nearly 

 flat below, tapering fairly gradually in front and behind, but 

 narrower in front. The margins of the body are rather 

 broadly rounded. The brown colour of the dorsal surface 

 assumes in spirit a characteristic purplish tint, with numerous 

 minute white specks, and the median stripe of yellow is very 

 well defined, about one-eleventh of the total width.
