1883Lankester in Encycl. Brit. XVI. 652/1 If we start from the condition of full eversion of the tube and watch the process of introversion, we shall find that the pleurecbolic variety is introverted by the apex of the tube sinking inwards. Ibid. 652/2 The Gastropod's introvert is pleurembolic (and therefore acrecbolic). |
