muscles, and its health and vigour. It is fre- 

 quently seen with eggs attached to the body, and 

 is often found in water where decayed leaves and 

 Algae are abundant. 



Anurcea squamula (Drop IV. fig. 15). There 

 are many species of this genus, but they are all 

 known by being without a tail or foot, and most 

 of them carry their eggs attached to the body ; 

 they possess an eye, and swim very rapidly. The 

 lorica of the species squamula is smooth, rounded 

 at the base, having horns in front, rather flat 

 when seen sideways, and slightly curved : it has 

 usually one egg of considerable size attached. 

 A. stipitata has the lorica nearly square, with six 

 spines in front, and one at the base, which might 

 be taken for a tail, but it is quite rigid.
