  Pleuroperitoneum \Pleu`ro*per`i*to*ne"um\, n. [Pleuro- +
     peritoneum.] (Anat.)
     The pleural and peritoneal membranes, or the membrane lining
     the body cavity and covering the surface of the inclosed
     viscera; the peritoneum; -- used especially in the case of
     those animals in which the body cavity is not divided.


     [1913 Webster]
  
     Note: Peritoneum is now often used in the sense of
           pleuroperitoneum, the pleur[ae] being regarded as a
           part of the peritoneum, when the body cavity is
           undivided.
