TARDIGRADA: NEW ZEALAND 113 



according to Plate the forked process should be c, there are no lateral setae except a, 

 and there is no mention of fringe. I do not consider forked processes as of any specific 

 importance. They occur as " sports " in various species, and very often only the 

 process of one side is forked. The lateral processes, c and d, are those most commonly 

 forked. 



Echiniscus, sp. ? (Plate 1TV. Fig. 7) 



Size moderate, 220 ^ in length ; plates nine, V. and VI. joined, two pairs, two 

 median. Lateral processes, a, c, d, e a a seta 120 M long, c a seta of 90 M, d and e 

 short curved spines of 20 n. Dorsal processes, over c a seta of 90 n. 



Lack of information about surface texture, fringe and claws, makes identification 

 impossible. 



Habitat. Among the moss Thuidium at the Hermitage, Mount Cook. 



No affinity with any known species can be suggested. There is no species which 

 has c a long seta, and d and e short spines. 



Echiniscus, sp. ? (Plate XV. Fig. 8) 



Very small, length 130 M ; plates nine, V. and VI. joined, two pairs, two median. 

 Lateral processes, a, c, d, e a a curved seta, 50 p. long, with a small blunt "auricle" 

 at its base, c and d short curved spines of 10 and 15 M, e a curved seta of 70 M. The 

 fringe of the fourth legs has short blunt processes. The claws were not seen. 



The surfase markings were small and regular, but could not be definitely stated 

 to be either pits or papillae. The posterior borders of the second paired plates and of 

 plate VI. between the slits, showed an undulation like that of E. perarmatus (20) so 

 that in all likehood the dots are papillae. 



This little animal has a very distinctive form. The paired plates have an 

 anterior narrow portion forming a distinct roll, which shows on the outline, and the 

 posterior edge diverges widely laterally. No other species besides perarmatus 

 shows the dots on the edge of some of the plates. 



It is very probably a distinct species, but the small size indicates that it may be 

 a larva, and as the claws were not seen the study cannot be completed. 



Habitat. Among New Zealand moss, note of the locality lost. 



There is no close relationship to any known species. In this section of the genus 

 there is none which has a and e long setae, and c and d short spines. 



Echiniscus, sp. ? (Plate XV. Fig. 9) 



Small, length ISO/*; plates nine, V. and VI. united, two pairs, two median. 

 Lateral processes, a, c, d, andV- a curved seta of 70 M, c a long slender spine of 

 50 M with bulbous base, d a short curved spine of 25 /&, e a seta of 65 /* Dorsal
