CYCLOrS. 



The ovaries consist of two sacs, which have the appearance of 

 bunches of grapes attached to either side of the posterior extremity 

 of the body, as shown in A, fig. 2. The eggs are globular, and are 

 enclosed in a transparent membrane. The centre of each egg has 

 an opaque colour, some being green and others red. Their number 

 increases with the age of the female, and when they have attained 

 a sufficient maturity the embryo of the future animal may be 

 seen within them with a magnifier. Mr. Pritchard has distinctly 

 seen these with a single lens with a focal length of about the 25th 

 of an inch. At the extremity of the alimentary canal the tail 



divides into two portions, whose extremities are fringed with 

 bristles, which present the appearance of splendid plumes. 



The alimentary canal and its peristaltic movements are dis- 

 tinctly visible in specimens which are only slightly coloured. 

 Above this canal two others can be observed, through which the 

 eggs are projected to the ovaries at each side of the tail.
