Scarabus albovaricosus, Reeve, Conch. Icon. sp. 4, pl. 1. figs. 2, 6. In looking over a lot of about 200 specimens of P. pollex, I found amongst them an example of Pfeiffer's P. albovaricosa, which does not differ in a single feature from five Solomon-Island specimens received from Dr. Cox. I cannot indicate the island whence the shell was obtained, but am inclined to believe it was Kantavu. Dr. Pfeiffer and Reeve, on the authority of Cuming, cite Celebes as habitat of this species ; and Dr. Cox, in his valuable paper on the " Nomenclature and the Distribution of the genus Pythia," says it is a common Solomon-Island species. As it is now well ascertained that many of Cuming's localities are erroneous, the former habitat needs confirmation. This species may be characterized by its large size (31 to 44 millim.), rather light texture, oblong-ovate form, smooth body-whorl, the upper part of which, together with the spire, is marked by short, longitudinal, slightly arcuated grooves. Colour light or dark chestnut, sometimes light fulvous with very small darker irrorations. The varices are white with wide black or dark chestnut margins, and the six specimens now before me all have a large lateral diffused blackish patch on the front and back of the body-whorl. Aperture luteous or whitish. Palatal teeth 4 or 5. 3. PYTHIA SAVAIENSIS, Mousson. Pythia pantherina, A. Adams, var. uveana, Mousson, Journ. de Conch. 1S65, p. 177 ; Schmeltz, Cat. Mus.

Dr. Graffe obtained it at Ovalau, Samoa, and Tonga group. I gathered several hundred examples at Wallis Island (=Uvea or Uea), one of the latter group. A solid, ovate, umbilicated (rarely imperforate) specie?, 21 to 28 millim. long, with the striation of P. pollex, and the lower parietal fold simpleT the upper one is small and trilobed. Colour corneous or yellowish-horn colour mottled with chestnut, rarely uniform light or dark chestnut. Varices spotted with white, and the aperture is luteous. The palate is furnished with 4 or 5 teeth. The small size, absence of bands, uniform shape, and the simple lower parietal fold will readily separate it from P. pollex. Mousson's name savaiensis is derived from Savaii, one of the Samoa |
