Bathyodontus cylindricus Fielding, 1950

Morphology and Anatomy:

	Body cylindrical from the middle of the neck to a short distance in front of the anus. Lateral chords granular, about1/3 as wide as the body except at the extremities. Lips almost continuous with the neck contour, bearing an inner circlet of six and an outer circlet of ten papillae. Amphids small, cup shaped, about 1/4 as wide as lip region. The single ventral tooth is located at the base of the cylindroid buccal cavity. Esophagus cylindroid, with five esophageal gland nuclei . Cardia large, irregularly shaped. Each cell of the thick walled intestine contains a group of fine granules. Rectum equal to anal body diameter. Tail hemispheroid, with an axial terminal pore which probably has a spinneret-like function, with a valve and a large gland anterior to it on each side of the body. Female: Vulva a transverse slit. Vagina refractive, extending almost 1/2 the way across the body. Ovaries symmetrical, reflexed 1/2 the way back to the vulva.
