 Having examined numerous specimens from Victoria, New 

 South Wales, and New Zealand, I have arrived at the conclu- 

 sion that Moseley's Coznoplana sanguined, Hutton's Rhynclio- 

 demus testaceus, Fletcher and Hamilton's Geoplana rubicunda, 

 and my own G. alba are all specifically identical, and I there- 

 fore propose to revert to Moseley's original name. 



It is a curious fact that Captain Hutton was unable to find 

 eyes in the specimens described by him, for a very closely 

 allied eyeless species {Geoplana typhlops) occurs in Tasmania. 

 I have/however, found the eyes in all the New Zealand speci- 

 mens, from various localities, examined by me, and am there- 

 fore disposed to believe that they were simply overlooked, 

 owing to their unusually sparse development in this species. 



Localities.— New Zealand: Dunedin (Hutton) ; Wellington 

 (Hutton) ; near Napier (coll., A. Hamilton, Esq.) ; Tarawera 

 township (coll., author) ; near Auckland (coll., T. Steel, Esq.). 



Geoplana triangulata, n. sp. 



Body, when at rest, broad and very much flattened, but at 

 the same time long and strap-shaped ; often with a more or 

 less pronounced median dorsal ridge ; flattened or even very 

 concave below ; with thin translucent margins. When crawl- 

 ing, very active, and capable of great elongation, becoming 

 correspondingly narrowed at the same time; tapering gradually 

 in front and behind, but broader towards the posterior ex- 

 tremity ; more or less triangular in cross-section. Eyes as 

 usual in the genus ; numerous, but very small, and rarely in 

 more than single series ; continued round the horse-shoe- 

 shaped anterior tip. 



The dorsal surface has a dark purplish-brown colour for the 

 median two-thirds, or thereabouts, of its breadth. This colour 

 shades off rather abruptly into a translucent marginal band of 

 pale-yellowish colour, peppered with numerous minute specks of 

 dark-grey. In the posterior portion of the body there may be 

 a very narrow mid-dorsal stripe of darker colour. The anterior 

 tip is pale pinkish-yellow. The ventral surface is pale-yellow- 

 ish, thickly peppered with minute grey specks. 



In spirit the body is broad and strap-shaped, bluntly 

 pointed behind, and much more gradually tapering in front. 

 The peripharyngeal aperture is situate at about the junction of 

 the middle and posterior thirds, and the genital aperture is 

 somewhat nearer to it than to the posterior extremity.
