rhynchostome1894

1894 Jrnl. Royal Microsc. Soc. 328 Oswald proposes to call the space between the introvert or proboscis [of certain gastropods] and its sheath the rhynchodæum, its anterior opening the rhynchostome, the opening at the apex of the proboscis the pharyngostome, and the oral aperture proper, where ectoderm joins the endoderm, the gastrostome.

1976 Biol. Bull. 150 65 The rhynchostome is applied to the insect and the soft parts are sucked out, leaving the exoskeleton and any internal hard parts.

2004 Toxicon 44 516/1 The proboscis is everted through a pore at the tip of the head, the rhynchostome.
