TARDIGRADA: NEW ZEALAND 109 



getting only a few hundred yards through it, without encountering any tnoss worth 

 collecting, I came out on the shore again. There was a little islet with precipitous 

 sides, cut off from the main island at high water. On the summit of the islet there 

 was only some scrubby bush and deep cushions of some large mosses. These were 

 not of sorts usually favourable to microscopic life (they were large Dicrana, and 

 Hylocomium and the like), and we did find them very unproductive, but among other 

 things we got five kinds of Tardigrada. 



No collecting was done in the South Island during the second visit, in 1909, but 

 a week was spent in the volcanic region of Rotorua, in the North Island. The 

 country had the look of being habitually parched and dusty, and was not mossy, 

 though there were mosses enough in shady nooks by springs and waterfalls. Hot 

 springs and cold springs were examined, the lakes were netted, and the mosses were 

 washed, but no water- bear of any genus appeared to reward our exertions. 



Two members of the Expedition, Mawson and Mackintosh, fetched me moss from 

 a considerable elevation on the slopes of the volcano Ngauruhoe, but this also was 

 unproductive. 



Summary of previous knoivledge. Scarcely anything is known of the Tardigrada 

 of New Zealand. Captain Hutton's Index, 1904 (10), makes no mention of the 

 group. The only paper I know on the subject is Professor Ric liters' " Moosfauna 

 Australiens " (37), in which three species are noted from the North Island, and from 

 Bare Island, a little islet near Napier, on the east coast. They are Echiniscus 

 gladiator, E. novaizeelandice and Macrobiotus hufelandii. 



We found all these species again, but curiously enough we did not get the type of 

 E. gladiator, but only the spineless variety exarmatus, hitherto unknown outside of 

 Scotland. 



In February 1907 Mr. D. J. Scourfield gave me some moss which he had received 

 from Gisborne, N.Z. In this I found a single example of Macrobiotus nodosus, a 

 species discovered shortly before in Africa. The species did not occur in our 

 collections from New Zealand, but it was obtained by Captain Davis, when the 

 Nimrod called at the Macquarie Islands on the homeward voyage.
