166 J. MURRAY 



figured on the same plate (Fig. 44). It has the same number of lateral setae, but 

 they are a, b, c, and d, instead of a, c, d, e. 



It has a close resemblance to E. blumi, Richters (27.) The lateral setae are the 

 same in position and relative sizes. The differences are the lack of barbs on the 

 outer claws, the finer granulation, and the blunt processes of the fringe. The 

 absence of barbs on the outer claws is of little importance as a negative character, 

 since it varies with age. There is no indication that our animal is mature. Richters 

 figures E. blumi with very coarse granulation, and with the fringe of sharp spines. 

 Many examples had no dorsal processes. 



Echiniscus, sp. ? (Plate XX. Fig. 45) 



Description. Size moderate; length 212 /x. Plates nine, V. and VI. united, two 

 pairs, two median. Dots small, some appearing as perforations, irregular, of two 

 sorts, a larger dark, a smaller pellucid. Lateral processes four a a curved seta of 70 / ; 

 c, d, and e long, broad spines of 50, 50, and 80 M respectively. Dorsal processes 

 over c, a flat spine of 40 /x between this spine and the lateral one a spicule. The 

 lateral and dorsal spines are all rough. There is a fringe of obtuse processes on the 

 fourth leg. It was not ascertained if there were barbs on any claws. 



Habitat.-^-Among moss from the sea-shore of Victoria, British Columbia, one 

 example only. 



This appears to be a distinct species, but it is not sufficiently known, as only one 

 example was observed, and that might not be mature. There is no species known 

 with similar roughened spines. In E. duboisi they are spinulose, not rough, and the 

 animal is otherwise very different. 



Genus Milnesium, Doyere (2) 

 Milnesium tardigradum, Doyere (2) 



This, the most generally distributed of all water-bears, was only observed in 

 Ontario, where it occurred in two localities, near the Lake of the Woods and in 

 Ottawa. Length, up to 800 M. Four eggs seen in the body. 



Genus Mctcrobiotus, Schultze (42) 



A : SPECIES HAVING ROUGH EGGS 



Macrobiotiis hufelandii, Schultze (42) 



Abundant in all the Canadian localities visited ; eggs also plentiful. In the 

 Rocky Mountains it attained a length of 1200 /.-, being the largest water-bear I 

 have measured.
