BATHYBIUS, 53 
water Protamceba (Fig. 8). The history of the life of an 
orange-red Protomyxa adrantiaca, which I observed at 
Lanzerote, one of the Canary Islands, is given in Plate I. 
(see its explanation in the Appendix). Besides this, I here 
add a drawing of the form of Bathybius, that remarkable 
Moneron discovered by Huxley, which lives in the greatest 
depths of the sea in the shape of naked lumps of pro- 
toplasm and reticular mucus (vol. 1. p. 344). 
Fic. 9.— Bathybius Hec- 
kelii, the “creature of primeval 
slime,’”’ from the greatest depths 
of the sea. The figure, which is 
greatly magnified, only shows 
that form of the Bathybius which 
consists of a naked network of 
protoplasm, without the disco- 
liths and cyatholiths which are 
found in other forms of the same 
Moneron, and which perhaps may 
be considered as the products of 
its secretion, 
The Amebe of the present day, and the organisms most 
closely connected with them, Arcellide and Gregarine, 
which we here unite as a second class of Protista under 
the name of Amceboidea (Protoplasta), present no fewer 
genealogical difficulties than the Monera. These primary 
creatures are at present usually placed in the animal 
kingdom without its in reality being unlerstood why. 
For simple naked cells—that is, shell-less plastids with a 
kernel—occur as well among real plants as real animals. 
The generative cells, for example, in many Algz (spores 
and eggs) exist for a ionger or shorter time in water in the
