papillar การใช้

Sinistral spiracle, blunt tail, labial papillar row interrupted on anterior and posterior portions, and a labial tooth row pattern of I, 1 / 1, II.
The anterior portion of the vagina forms a wide chamber, closed posteriorly by a valve-like papillar structure; the interior walls are slightly darkish in colour, and weakly longitudinally plicated.
The penis opens into the posterior portion of the papillar structure in the form of a small tube; it proceeds through the thick vaginal wall in an oblique anterior direction, and becomes slightly enlarged or bulbous towards its termination.
