A spirit specimen 27 mm. long by 4 mm. wide at broadest part, 

 has the dorsal pigmented area 3 mm. in width and bordered by 

 A mm. of yellow margin. 



The eyes, which are in a single row . with a few scattered 

 individuals, are rendered conspicuous by being situated on the 

 light-coloured margin which extends all round at the tips as well 

 as the sides, completely framing the coloured area of dorsal 

 surface. The submarginal stripes are entirely absent, the ventral 

 surface being uniform white or pale yellow. 



In same specimen the peripharyngeal opening is 15 and the 

 genital 20i mm. from anterior tip.

 Stuart Dove). 



In a small collection of land planarians from Rotorua, New 

 Zealand, given to me by my friend Mr. C. Cooper, of Auckland, 

 there is one small specimen, probably immature, of an apparently 

 undescribed form, which bears a remarkable resemblance to the 

 above variety. This specimen in formaline has a very dark 

 brown narrow dorso-median line with dark brown on either side, 

 paler next median line, and darkest next marginal space. 

 Marginal space cream-white. Marginal spaces each \ of total 

 width, coloured area ^ of same. Length 12 mm. by 2 mm. in 

 width. Peripharyngeal aperture 9 mm. from anterior tip, genital 

 opening not visible. Anterior tip brown, not inclosed by light 

 margin, differing in this respect from the above-described Tas- 

 manian form. Eyes in a single somewhat straggling row, with 

 bare indications of grouping. 



The only external point of difference between this little 

 planarian and a small example of G. Tasmaniana var. Jiavicincta, 

 is that the pale margin does not extend round the anterior tip.

This species was not figured by Dendy, and by his description 

 alone it is not easv to distinguish from G. Tasmaniana. Graff,
