on the other hand, the anterior margin appears as though the plate 

 were there bent over, showing the dots in profile, as " dimples." 



Dots of two kinds are also found in a Scottish species which I 

 identify as U. oihonnce. In that case the dots are all of equal size, 

 and the darker ones look as though one here and there of the 

 pellucid dots had been punched out, leaving a hole. Though 

 Professor Eichters makes no reference to the texture in " Nordische 

 Tardigraden " (9), nor in " Arktische Tardigraden " (10), his figure 

 in the latter work (plate xv. fig. 4) gives colour to the belief that his 

 animal had also two kinds of dots. 



Skins with two and three eggs were seen. 



Cape Colony. One of the most abundant species. The name is 

 given in reference to the protection of the legs, as well as the back, 

 by spines. 1 know no other species with such spines on the 

 2nd and ord legs, though the spine on the 1st leg is common to 

 nearly all -Echi nisei. 



E. longispinosus sp. n., plate XVII. fig. 3. 



Specific Characters. — Size, moderate. Plates, 9 : 2 median, 2 pairs, 

 V. and vi. united, 3-lobed, 5 faceted. Lateral processes, a, c, and d, 

 long fine seta. Dorsal processes, a long fine seta on the angle of 

 each plate of the first and second pairs (segments iii. and iv.). 

 Four setse round mouth, long, and palps large. Coarsely punctate, 

 dots distant. Fringe of long peg-like processes, standing apart, 

 on the fourth leg. 



Length, 200 /x.. Eyes red. Fringe hyaline. No barbs could 

 be detected on the inner claws. In such cases minute barbs may 

 be present, as in E. mutahilis (3) but they may be readily over- 

 looked. The eight posterior setae (on the paired plates) are equal 

 and very slender. 



The dots are of unequal size and very widely spaced. They 

 look like depressions. The eggs were not seen. 



The name refers not only to the principal setse, which are, 

 however, not so long as in some other species (E. merokensis, 

 E. oihonnce, etc.), but to the elongation of all the lesser processes. 

 The mouth-bristles and the teeth of the fringe are relatively longer 

 than in any other species known to me. 



Cape Colony. One example seen. Though no eggs were found 

 to indicate maturity, the species is sufficiently distinct from all other 

 known species. 



The faceting of the plate formed by the union of segments v. 

 and vi. is shared by several species. E. reticulatus Murray (3) has 

 only 4 facets, E. meridionalis Murray (4), and another (unnamed) 

 species from the South Orkneys have 5 facets just like E. longi- 

 spinosus.
