Dendy. — On New Zealand Land Planarians. 231 



under a log on the Teremakau Flat, near Jackson's : " When 

 at rest broad and flat. When crawling, which it does very 

 rapidly, the ventral surface is flat and the dorsal strongly 

 convex, with the anterior end elongated and narrow and the 

 posterior end broader but gradually sharp - pointed. The 

 dorsal surface was shining-black all over, but in a good light 

 a fine median longitudinal darker line could be distinguished, 

 and where stretched by a contained egg-capsule a brownish- 

 black mottling could also be distinguished. There was a nar- 

 row marginal band of pale-brown, and the ventral surface was 

 pale-brown mottled finely with a darker tint. The length of 

 the animal when crawling fully extended was about 85 mm., 

 and the breadth about 6 - 5 mm. The cocoon was extruded 

 through the back of the animal when placed in dilute 

 alcohol." 



Another specimen when at rest measured about 35 mm. 

 by 10 mm., was not quite so black, and had a distinct narrow 

 median whitish band on the ventral surface. Two more 

 specimens also show the pale mid- ventral band. 



Locality. — Under logs on the Teremakau Flat, near Jack- 

 son's (West Coast Eoad). February-March, 1898. Four 

 specimens. 



Geoplana graffii, var. occidentalis, Dendy. 



Near Jackson's (West Coast Road). — February-March, 

 1898. One specimen, resembling those previously obtained 

 from Otira, and, like the latter, differing from the Lake 

 Mahinapua specimens in the possession of comparatively 

 large (in spirit) whitish specks on the dark portions of the 

 dorsal surface. The specimen was found beneath a log on the 

 Teremakau Flat. 



Geoplana iris, Dendy. 



Peel Forest.— March, 1898. I received from Mr. W. W. 

 Smith eight specimens collected in this locality. They 

 showed in life the typical colouration, except that the outer 

 margins of the dorsal orange stripes were yellow rather than 

 green, but sometimes with a greenish tint in the case of the 

 more median ones. They are mostly considerably larger 

 than the original specimens, the largest specimen in spirit 

 measuring 38 mm. in length by 8 mm. in greatest breadth, 

 with the genital aperture 9 mm. and the peripharyngeal 

 aperture 17 mm. from the posterior extremity. The body in 

 spirit is flat below, convex above, broader behind than in 

 front. 



The species makes a very near approach to the Victorian 

 G. adcB, as well as to G. graffii and its allies in New Zea- 

 land.
