This is a well-characterized species, but it appears to be 

 related to G. suteri and G. sxibquadrangulata. I am indebted 

 for the two specimens to Mr. H. Suter.

Geoplana mariae, Dendy. 



Near Mr. Garvey's House, Clinton Valley, Head of Lake Te 

 Anau. — I found one small specimen which is probably a young 

 individual of this species. The colouration and the shape 

 of the body in spirit agree closely with the typical form, but 

 I was unable to make out the eyes and apertures. The living 

 animal is thus described in my notes : " When crawling long 

 and narrow. Triangular in section, dorsal surface forming a 

 prominent ridge, ventral flat, tapering gradually in front and 

 behind. Dorsal surface yellow speckled with olive-brown, the 

 brown specks concentrating on each side of a narrow median 

 stripe of yellow, up the middle of which runs a row of very 

 minute indistinct pale -brown spots. Anterior tip slightly 

 pinkish. Ventral surface pale yellow flecked with minute 

 specks of pale brown, which are absent in the middle line." 



In spirit the body exhibits the characteristic convexity of 

 both surfaces and uniformity of diameter almost to the ex- 

 tremities.

The following notes were read by Mr. A. J. Rutherfurd, 

 Chairman of the Wellington Acclimatisation Society, at the 

 quarterly meeting of that body on the 3rd December. The 

 subjects dealt with are chiefly a description of the waters into 

 which salmon and trout have been introduced in New Zealand, 

 and the results likely to be obtained owing to the change in 

 their surroundings : — 



I. Environment. 



Situated between latitudes 34° and 47° S., in the Pacific 

 Ocean, about a thousand miles from the main Australian 

 Continent, the islands of New Zealand form an exceedingly 

 interesting group, with their unique flora and fauna. They
