median band are a number of irregular, more or less discon- 

 tinuous and anastomosing, narrow, wavy, longitudinal stripes 

 of the same dark chocolate-brown colour. This fine longi- 

 tudinal striation extends to the margin of the dorsal surface on 

 either side. In addition to the dark stripes, numerous minute 

 specks of the same colour occur, chiefly in the ground-colour 

 on each side of the mid-dorsal band. 



The ground-colour of the ventral surface in life is dirty- 

 white, with tw r o broad longitudinal bands of chocolate (paler 

 than that of the dorsal surface) dividing the ground-colour 

 into three narrow stripes, one median and one submarginal on 

 each side. A few minute specks of chocolate-brown occur 

 sparsely scattered in these bands of ground-colour. Anterior 

 extremity in life pinkish. 



This is a very distinct and well-characterized species. 



Localities. — Chatham Island ; common ; widely dis- 

 tributed in and under rotten logs (Whangamarino, Whare- 

 kauri; January, 1901). Ara-tea-tea, North Island of New 

 Zealand ; one very typical specimen ; coll., E. M. Laing, 

 Esq. 



Geoplana garveyi, n. sp. 



Body even when at rest long and narrow, very gradually 

 tapering behind, convex above and flat beneath. When 

 crawling very long and narrow, the larger of the two speci- 

 mens attaining a length of about 50 mm. In spirit the 

 larger specimen measures about 42 mm. by 2-5 mm., and the 

 smaller about 32 mm. by 2*5 mm. In the larger specimen (in 

 spirit) the genital aperture is distant 21 mm. and the peri- 

 pharyngeal aperture 29 mm. from the posterior extremity ; 

 in the smaller specimen the corresponding distances are 

 135 mm. and 19'5mm. The shape in spirit is long and 

 narrow, more gradually tapering behind than in front, con- 

 vex dorsally and flat ventrally, but with gradually rounded 

 margins. 



The colour in life was an almost uniform bluish-grey,, 

 rather paler in the mid-dorsal line and at the margins. The 

 ventral surface paler grey, except for a pair of ill-defined 

 longitudinal stripes (or, one might say, grey, fading in the 

 middle line and towards the margins). The anterior tip was 

 pinkish-brown. 



Eyes numerous, continued laterally almost to the extreme 

 posterior end, but more abundant at the sides of the anterior 

 end. 



The species is evidently nearly related to G. purpurea, 

 from which it differs in colouration. 



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

 of Lake Te Anau ; in rotten trees. January, 1900.
