It appears to me almost certain tliat this species is identical 

 witli Moseley's Geoplana sanguinea from Australia, and that 

 Fletcher and Hamilton's G. rubicunda and my own G. alba, 

 from New South Wales and Victoria respectively, are also 

 identical. I have received specimens from Auckland, and 

 have collected it myself at Tarawera township in the centre 

 of the North Island ; while Captain Hutton records it from 

 Dunedin and Wellington. 



I have not seen any specimens without eyes, as in the 

 original description, and I believe that they are always present, 

 though not so evident as in other members of the genus. It 

 must, however, be remembered that in the closely related 

 Tasmanian G. typhlops'^ the eyes appear to be certainly 

 wanting. 



4. Geoplana triangulata, sp. n. 



This is a large species, commonly about o inches long when 

 crawling and rather broad. In general form and habits it 

 resembles G, iestacea, to which it appears to be nearly related. 

 It is, however, distinguished from that species by the presence 

 of characteristic markings. There is a very broad band of a 

 dark purplish-brown tint, occupying the middle two thirds or 

 thereabouts of the dorsal surface. Outside this band the 

 margins of the body are thin and translucent, and of a pale 

 yellowish colour peppered with numerous minute specks of 

 dark grey. The ventral surface is pale yellowish, thickly 

 peppered with minute grey specks. 



The name triangulata is given on account of the presence, 

 under certain conditions, of ,a strongly-marked median dorsal 

 ridge, a character also found in the Victorian G. alba. 



This worm is very common in gardens about Christchurch, 

 It feeds upon earthworms and is frequently dug up with the 

 spade. It is also found under old wood &c. as usual. 



A variety of this species occurs at Dunedin, characterized 

 by the absence of the grey specks from the margins and 

 ventral surface. A specimen of this variety in the Dunedin
