Rotifera of Neic Zealand. By J. Murray. 581 



Elosa worrallii Lord (7). 



This curious animal, with its hizarre optic arrangements — one 

 eye on the side of its nose, and the other in the back of its neck, so 

 to speak — appears to be rare. I have usually found it among 

 Sphagnum, but in New Zealand it was obtained from a pond in 

 the Mount Cook district. 



Dinocharis inornatus Hilgendorf {3). 



In both islands : ponds at the Hermitage, Mount Cook, and on 

 Mount Wakefield, 6000 feet ; pond at Rotorua. Hitherto only 

 known in New Zealand, but we afterwards obtained it in Sydney. 



Stephanops tcncllus Bryce (1). 



This energetic little atom may not be rare, but it is so very 

 small and so very lively, that it is little likely to be recognized for 

 the Rotifer it is. In my experience it has occurred pretty fre- 

 quently among moss, chiefly from warm countries. 



Metopidia latusinus Hilgendorf (3). Plate XVII. figs. 11a, 11 J. 

 Synonym : M. solidus var. latusinus Hilgendorf. 



This interesting species was only obtained in one place, in an 

 ice-cold stream issuing from a glacier in the Mount Cook district. 

 It was abundant on Myriophyllum. 



I was able to convey some specimens to Mr. Rousselet, and it 

 is supported by his authority that I decide to recognize it as of 

 specific rank. There is considerable variation in the width of the 

 sinus, as our two figures show, which no doubt led Mr. Hilgendorf 

 to subordinate it to M. solidus. 



Pcdalion sp. 



In the pure cold water of Lake Wakatipu, South Island. Peda- 

 lion has been so often reported from ponds and shallow waters, 

 that I was rather surprised to find it as a plankton species in a 

 great lake. 



Unfortunately I had never seen it before, and did not know the 

 specific differences. My rough sketch does not show the short pro- 

 cesses near the posterior end, which distinguish P. mirvm, nor the 

 cuspidate point of a more recently discovered species, so the pro- 

 bability is that it is P. fennicum. 



I succeeded in preserving many, but the bottle was one of several 

 which have not arrived home.
