TARDIGRADA: NEW ZEALAND 117 



dry for two and a half years. Only a small proportion of the individuals revived when 

 the moss was moistened. The relation of the egg to the animal was demonstrated by 

 the presence in some of them of young in which the pharynx and claws could be seen. 



Eggs of Macrobiotus having close-set processes, nearly or quite hemispherical, 

 have been figured by Richters and myself. In his " Eier der Tardigraden " (32), 

 Plate V. Fig. 4, Richters figures one such as apparently a variety of M. echinogenitus. 

 In "Scottish Alpine Tardigrada" (14), Plate IH. -Fig. 10, I show an egg which in 

 all probability is that of M. nwntanus. A similar egg occurred in Nova Zembla, 

 and is figured in "Arctic Tardigrada" (19), Plate XLV. Fig. 4. 



According to Doyere (2), confirmed recently by Richters in a letter, M. ober- 

 hiiuseri has an egg of similar form, with rounded processes. 



Macrobiotus intermedius, Plate (23) 



In many localities in the South Island ; Hills at Lyttelton, Otira Gorge, near Lake 

 Wakatipu ; Mount Cook district, at an altitude of 5000 feet on Mount Wakefield ; 

 near Auckland, North Island. 



The eggs were found near Lyttelton. They had not the typical top-shaped 

 processes, expanded upwards. They were narrower at the top, like truncate cones, 

 of a height equal to the breadth of base, and with a very slight indication of 

 expansion at the top. The processes were separated by spaces rather greater in 

 diameter than their bases. The exposed surface of the shell between the processes 

 was finely papillose. 



Professor Richters informs me in a letter that he knows a variety of M. inter- 

 medius which has processes very like those of M. hufelandii. This variety I have 

 also seen (see Australian Tardigrada, p. 139, in this paper). The variety from 

 Lyttelton is like it, but the processes are shorter, and not expanded into a disc 

 above. 



Macrobiotus dispar, Murray (16) 



Habitat. Many localities in the South Island ; a pond on the Moraine of the 

 Miiller Glacier ; on the Vegetable Sheep (Haastia), Mount Wakefield, elevation 

 about 5000 feet; on the Nun's Veil peak, elevation 6000 feet (collected by 

 Dr. Mackay) ; among tree-moss from the moist bush of the west coast. The simplex 

 condition also occurred. 



It is curious that, though usually dwelling in ponds, the species occurred only 

 once in a pond in New Zealand. In all other instances it was got among moss, or 

 moss-like vegetation (Haastia). 



The examples from the Nun's Veil had the two dorsal processes of the type, 

 which are often lacking.
