. Land snails from Hawaii, Christmas island, and Samoa. Snails; Mollusks; Mollusks; Mollusks. Pilshry, Cooke, Ned—Snails from Hawaii, Christmas, Samoa 19 that it is situated at no great distance, probably less than a quarter of a mile, though it may have been at a somewhat lower altitude. There is little doubt that both belong to the same geographical race. So]?T Anatomy The external portion of the animal is uniformly whitish with a slight yellowish tinge. The pedal grooves are shallow and very narrow but easily made out. Their position is shown in figures 3, ^, c, d. The sole is narrow and nearly smooth. The surface above the pedal grooves is very minutely granulose. The genital pore is placed very far forward and is almost under the base of the tentacle (fig. 3, a). The mantle is thin, colorless, and strongly indented where it meets the apertural folds (fig. 3, e). The lung cavity is long and narrow. The pul- monary vein is well defined and extends nearly to the collar. The kidney is long and narrow, and the urethra crosses over from near its base to under the intestine (fig. 3, /). The genital organs are remarkably simple (fig. 5). The penis is long- cylindric, tapering gradually towards the base, where it narrows rapidly just above the genital pore. Ordinarily it is widest where the vas deferens enters and does not taper to any extent above; the distal end is rounded. Three penes had the following measurements: Specimen B : length , diameter mm. (fig. 5, a, b) Specimen A: length , diameter mm. (fig. 5, d) Specimen C: length , diameter mm. (fig. 5, c).
