Shell large for the subgenus, 6 whorls, weakly convex, suture not im¬pressed, base angulate, nearly flat, narrowly umbilicate, 3 denticles at base of columella, aperture oblique, Urate within. Spiral sculpture of nodular cords, with slightly broader interspaces, 4 cords on 3rd whorl, 6 on penultimate whorl, counting the broad, weakly defined subsutural cord, but not the strongly projecting cord defining the base. Base nearly flat, surface glossy, with 7 narrow, low cords, broadly spaced but more closely spaced toward the umbilicus. Body whorl with fine spiral striae, but on the base the striae are broadly spaced and faint. Axial sculpture of fine growth lines. Color greenish-white with broad axial stripes of pinkish-tan, on the base the stripes are brown in the interspaces and bright pink on crossing the basal cords; base of columella and callus tongue bright green. Height 18.5, diameter, 20.2 mm.

Tegula picta has no doubt been regarded as the same as T. verrucosa sp. nov. (T. byroniana of authors), but differs in having 1/3 to 1/2 as many pustules onthe spiral cords, in having a glossy base with low, narrow cords rather than the coarse cords of T. verrucosa, and in having pinkish-tan rather than purplish-brown coloration. The 2 species are evidently closely related, but no intergradation has been observed. Tegula picta has a more restricted, more southern distribution. The name is taken from the Latin, "painted," and describes the bright pattern of coloration, the name taken from a manuscript label of W. H. Dall in the U.S. National Museum.
