Islands. He very correctly drops one i ; and Pease, who retains both, 

 spells it " savaiiensis." Both Schmeltz and Paetel erroneously 

 quote it as " savai/ensis." All, however, refer to one and the same 

 species.

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. Tiie varices, which 

 are not very conspicuous, are spotted with wiiite 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, 

 pi. 19. fig. 5 ; Schmeltz, Cat. Mus. Godeff. v. p. 87 ; Pfeiffer, Mon.

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 Na Viti Levu Bay in the N.E. part of Viti 

 Levu. Examples taken at the latter location were larger than the 

 Vuna Dawa siiells. 



Tb.is ver}' 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-iike, simple or 

 very rarely with a slight inferior lobe j)ri>jecting to the lelt. The 

 lower fold is compressed and fiirni>hed with a small, short, tooth-like 

 duplication. The columelhir plait is obliquely twisted and continuous 

 with the widely expanded peristome, which latter is simple above 

 and sli;:htly reflected below. Palate with four, rarely five teeth, two 

 of which are t!ie larger. Colour light to dark chestnut or reddish 

 chestnut, rarely light yellowish-horn colour, frequently indistinctly 

 mottled with a tint daiker than the ground-colour, and very olten 

 with a blackish sutural band. Varices rarily spotted with whitish. 

 Lengtli 15 to 24 millim. The adults are very frequently eroded 

 over the whole surface.
