Neck tapering principally in its anterior fourth until the lip region is about one-third as wide as the neck base. Cuticle with typical radial markings visible over entire body, especially on neck and tail. The inner portion of the six bluntly conoid lips is set off as a disc-like cap surrounding the vestibule. Amphids escutcheon-shaped, about half as wide as head. Spear length about equal to lip region width, its extensions slightly longer than the spear proper and bearing conspicuous knobs which appear especially prominent under the lower powers of the microscope. Esophagus at first a slender tube without visible radial musculature about one-fourth as wide as neck, and continuing thus to where it suddenly expands to form the enlarged basal portion. This enlarged part occupies about three-eighths of the total esophageal length and the radial muscles are less prominent. The three conspicuous esophageal glands are easily seen. Cardia elongate-conoid, one-third as wide as neck. Intestine apparently four cells in circumference, these cells well filled with dark refractive granules. Prerectum length about twice body diameter. Vulva transverse, vagina extending somewhat forward. Ovary reflexed half way to vulva. Posterior uterine branch absent. Tail bluntly conoid, slightly variable in form, frequently more conoid than illustrated. Male unknown.
Habitat: Soil from stream bank, Aspen Creek, Mt. Timpanogos, Utah, U.S.A. Elevation about 7,000 feet. Common in moist soils, Germany, Eastmark of Germany, Holland and Switzerland.
