NATURAL HISTORY. 83 
The ovaria consists of two bags, presenting a 
similar appearance to clusters of grapes, and 
being of considerable magnitude, compared 
with the size of the animal, they give it a novel 
and peculiar character. The eggs are of a 
globular figure, and enclosed in a transparent 
membrane, independent of their shelly ovarium. 
The centre of each egg is of a deep opaque 
colour, which in some specimens is green, in 
others red. Their number increases with the 
age of the parent, and when sufficiently matured, 
the embryo of the future animal may be per- 
ceived under a deep magnifier. At the termi- 
nation of the alimentary canal the tail is sepa- 
rated into two portions, and the ends of these 
_ bicaudal processes are furnished with branched 
seti, which form a beautiful plumed appendage. 
The coloured markings on the shell of these 
creatures vary in different specimens, as also do 
the colours of the ovaria. The majority are 
pellucid, and do not possess the beauty of the 
bright variegated red specimens from which the 
drawing was taken. Some are of a blueish green, 
others are red, with the ovaria green. 
Since the above description was first pub- 
lished, foreign naturalists have paid great atten- 
tion to the Entomostracans,and have ascertained
