PLATE III 



MICROPHOTOGRAPHS OF WATER-BEARS 



FIGURE 9. Side view of the common Antarctic species of Water-bear, Macrobiotus 

 arcticus, which is also found in the Arctic Region. In the photograph may also 

 be seen a Eotifer and some filaments of Algae. 



FIGURE 10. Dorsal view of another example of the same species. Four eggs at an 

 early stage of development can be seen in the body. To the left of the animal is 

 one of the eggs of the species, but it is so encumbered by debris that its 

 characteristic peculiarities cannot be seen. 



FIGURE 11. A different species of Water-bear (Macrobiotus oberhduseri] found among 

 moss at Cape Royds. It has one excessively long claw on each foot, and the body 

 is marked with a warm brown colour, forming longitudinal and transverse bands, 

 indicated in the photograph.

 FIGURE 12. Another example of Macrobiotus arcticus, containing six eggs not very 



far advanced in development. In the anterior part of the body the fat-cells in 

 the body fluid can be distinguished.
