1.5 mm; a= 29; b= 5.6; c= 25; V=53

    Transverse striae rather coarse.  Lips low, rounded, amalgamated, set off by slight depression.  Amphids wide and deep.  Spear length, exclusive of extension, one and one-half times lip region width.  Spear extension and muscles surrounding it conspicuous but not forming flanges.  Esophagus enlarged by gradual expansion just back of middle.  Three esophageal gland nuclei easily seen.  Cardia elongate-hemispherical.  Intestinal cells with fine brown granules.  Rectum about as long as tail.  Prerectum rice length of rectum.  Ovaries long, reflexed about half way to vulva.  Egg length one and one-third times body width.  Tail conoid arcuate to small blunt terminus.

    Diagnosis: Enchodelus with the above  measurements and general description.  Most closely related to E. macrodoroides and E. brevidentatus, differing in the form of lip region and relative proportions of spear.  Above formula from gravid Virginia specimens.  Those from Arizona and Utah attained a length of 2 mm; vulva of Arizona females as 48%, tail a little more slender than that figured from Virginia.

    Habitat: One female from soil, pine woods, Arlington Farm,  Virginia, two from Kaibab Forest, Arizona, and three from sod, Tryal Lake, Uinta Mountains, Utah, U.S.A.
