 ordinary manner, so that the bodj has the shape of a ball, from which 

 the head and limbs project. The fluid is contained in the abdominal

 is caused by an extraordinary development of the ovaria ; these organs 

 become so large, that, not having room in the abdominal cavity, they 

 extend right across the back, where they coaleace, so that the body of the 

 animal is entirely surroimded by the mass of the ovaries."
