Extract

Confusion exists about the true nature of the guiding apparatus surrounding the spear in Dorylaims. Thorne and Swanger (1936), commenting on the guiding ring, say: “There are at least two types; the collapsible cylindrical form with cutinized borders that give the appearance of a “double” ring such as that of Dorylaimus stagnalis (Fig. 2A), and the single muscular ring as found in D. obscurus (Fig. 2E). From the guiding ring a thin sheath envelops the spear to its base”.
