Naesiotus pinzonensis
Caracol terrestre endémico de Galápagos, Naesiotus land snail
The shell is highly elevated, oval in outline. Height of shell 12.8-17.0 mm, width, 7.4-8.0 mm. The 6.1-6.9 whorls are very slightly convex. The embryonic shell consists of 1.7-2.3 whorls. The umbilicus is very narrow, 0.5-1.0 mm at its opening. The shell of live specimens is dark brown, often with a reddish, purplish or greenish tinge; a thin, light band can usually be seen along the periphery of the last whorl. The sculp- ture of the embryonic whorls is formed by very closely set, very fine, trans- verse grooves, 22-30 per mm near the end of the first embryonic whorl and 24-36, near the end of the second; the grooves sometimes fade out near the lower suture (PI. II, Fig. 2); the postembryonic whorls are smooth and lustrous, ornamented by 7-10 barely perceptible, intermittent, spiral lines. The aperture is oval; the columellar lip is reflected; the lips and parietal walls are reinforced by a slight, whitish callus.
