lacrimal papilla

Each Wolffian duct ends blindly in front, and the two unite behind to open by a common papilla into the cloaca.

Papillif′erous, papillate: bearing one or more fleshy excrescences; Papill′iform, like a papilla in form.

In case of failure to destroy an individual papilla, should a second attempt be made at the same sitting?

A short time after the appearance of the vacuoles the entire conidium extends itself so that the papilla disappears.
