Peltogastridae. 
Yyes Delage states that Sacculina lives in its younger stage in the 
abdomen of the crab, between the intestine and the wall of the body ; it 
is there found complete with its sac, ovaries, accessory glands, testes, and 
nervous system, and it is only by increasing in size that it produces by 
compression necrosis of the integuments of the crab, thinning and finally 
rupturing them, to break through to the outside. Shortly afterwards, 
complementary males in the shape of Cypris attach themselves to it, 
usually ;two to five to one adult. C.R. xcvii. pp. 961-964, 1012, &
