junction of the dorsal and ventral surfaces. (A few very 

 minute specks of brown occur in each of the yellow stripes of 

 ground-colour.) 



Anterior tip bright pink. Ventral surface very pale yel- 

 low, mottled thickly with small specks of light, dusky brown. 

 Three narrow longitudinal bands are almost free from the 

 mottling; one of these is median, and the others are just inside 

 the dark marginal lines. 



In spirit the dorsal surface is strongly convex, while the 

 ventral surface is concave, with slightly prominent margins. 

 The peripharyngeal aperture is somewhat behind the middle, 

 and the genital aperture slightly nearer to it than to the 

 posterior end. 



Locality. — Lincoln Agricultural College, beneath a heap of 

 mangolds (one specimen ; coll., P. Marshall, Esq.). 



Geoplana laingii, n. sp. 



When at rest, short and thick, slug-like, with convex dorsal 

 and ventral surfaces, and narrow crinkled margins. When 

 crawling, long and narrow, much flattened below ; ridged on 

 the dorsal surface so as to be triangular in cross- section ; 

 tapering gradually in front and behind ; slimy and sticky as 

 usual, but with the dorsal surface minutely rugose or warty 

 (granulated) both when at rest (contracted) and when fully 

 extended. This granulation seems to be a well-marked cha- 

 racter of the species. Length when crawling, about 80mm. ; 

 breadth, 4mm. Eyes as usual, but comparatively small and few. 



Ground-colour of dorsal surface yellowish-brown, finely 

 mottled with darker tint of same. In the mid-dorsal line is a 

 narrow band of dull orange. This orange band is divided into 

 two by a very fine median line of darker brown, and is edged 

 on each side by a fine but distinct black line. It is also very 

 finely mottled with the darker brown tint which forms the fine 

 mediau line. 



Anterior tip pinkish. Ventral surface pale-yellow, finely 

 mottled with pale-brown. 



In spirit the body is very much contracted, short and 

 thick, convex dorsally and ventrally. The peripharyngeal is 

 situate at about the junction of the middle and posterior thirds, 

 and the genital aperture about half-way between it and the 

 posterior extremitj^. 



Locality. — Foot of Lake Taupo, North Island, under stones 

 (two specimens; coll., K. M. Laing, Esq.). 



Geoplana spectabilis, n. sp. 



When at rest the single specimen was broad, pretty 

 strongly convex on the dorsal surface, flat on the ventral, 

 tapering more gradually behind than in front. When crawl-
