Show 294 MR. A. GARRETT ON THE TERRESTRIAL [Mar. 1, Islands. He very correctly drops one i ; and Pease, who retains spells it " savaiiensis." Both Schmeltz and Paetel erroneously quote it as " savayensis." All, however, refer to one and the same species. 4. PYTHIA LENTIGINOSA, Garrett. Pythia lentiginosa, Garrett, Amer. Journ. Conch. 1872, p. 220, pl. 19. fig. 4; Schmeltz, Cat. Mus. Godeff. v. p. 87; Pfeiffer, Mon. Pneum. (Auric.) iv. p. 337 ; G. Nevill, Hand-list Mus. Calcutta, p. 222 ; Cox, Proc. Linn. Soc. New South Wales, vi. p. 604. This species occurred to me in only one location, a small islet close to the east end of Taviuni, where it was found in abundance associated with P. pollex. It is remarkably uniform in colour, and differs but little in shape and size. It is a solid, ovate or oblong-ovate shell, 21 to 29 millim. long, yellowish white, profusely spotted with small fulvous-brown maculations, and with a honey-yellow aperture. The varices, which are not very conspicuous, are spotted with white and chestnut, which on the sides of the body-whorl are elongated into stripes. The basal perforation varies from rimate to umbilicate. The lower parietal fold shows a very slight indication of an external groove. 5. PYTHIA PEROVATA, Garrett. Pythia perovata, Garrett, Amer. Journ. Conch. 1872, p. 221, pl. 19. fig. 5 ; Schmeltz, Cat. Mus. Godeff. v. p. 87 ; Pfeiffer, Mon. Pneum. (Auric.) iv. p. 34 ; Cox, Proc. Linn. Soc. New South Wales, Ti. p. 608. I collected about 2000 specimens of this species on the margins of mangrove-swamps at Vuna Dawa on the north side of Natawa Bay, Vanua Levu, and at N a Viti Levu Bay in the N.E. part of Viti Levu. Examples taken at the latter location were larger than the Vuna Dawa shells. This very distinct species is of an ovate or abbreviate-ovate shape, solid; spire short, base imperforate, sometimes rimate, more rarely perforated; longitudinally striated, the striae straight and most conspicuous above. The dentation is white or tawny ; the upper tooth on the parietal wall is vertical, elongate, crest-like, simple or very rarely with a slight inferior lobe projecting to the left. The lower fold is compressed and furnished with a small, short, tooth-like duplication. The columellar plait is obliquely twisted and continuous with the widely expanded peristome, which latter is simple above and slightly reflected below. Palate with four, rarely five teeth, two of which are the larger. Colour light to dark chestnut or reddish chestnut, rarely light yellowish-horn colour, frequently indistinctly mottled with a tint darker than the ground-colour, and very often with a blackish sutural band. Varices rarely spotted with whitish. Length 15 to 24 millim. The adults are very frequently eroded over the whole surface. |
