    • 1964, Michael T. Ghiselin, Reproductive Function and the Evolution of Opisthobranch Gastropods:
      In androdiaulic and triaulic forms the movement of sperm is largely by muscular action, but the function of congealing the sperm into a more or less unitary mass is retained by the prostate.
    • 2010, Janet Leonard, The Evolution of Primary Sexual Characters in Animals, page 161:
      Cervera et al. (2000) described three distinct patterns of division of reproductive systems of pleurobranchids producing three different triaulic arrangements.
