Show 312 MR. A. GARRETT ON THE TERRESTRIAL [Mar. 1, spiral lines more indistinct, and the periphery with a compressed keel. The peristome is thinner and not so much expanded. Diam. 9 millim. 6. HELICINA BERYLLINA, Gould. Helicina beryllina, Gould, Proc. Bost. Soc. Nat. Hist. 1847, p. 202 ; Expl. Exp., Shells, p. 95, fig. 111 ; Pfeiffer, Mon. Pneum. i. p. 354 ; Gray, Cat. Phan. p. 256 ; (Idesa) II. & A. Adams, Gen. Moll. ii. p. 304 ; Mousson, Journ. de Conch. 1865, p. 197, 1869, p. 357 (var. flavida), 1870, p. 200; Paetel, Cat. Conch, p. 125; Pease, Proc. Zool. Soc. 1871, p. 476 ; Schmeltz, Cat. Mus. Godeff. v. p. 98. I obtained numerous examples of this species at Vanua Balavo, where it occurs on the trunks of trees. Dr. Graffe found it at Kanathia and Oneata. Prof. Mousson has described the \ar. flavida from Samoa. About the same size but thinner than H. semperi, and the spire is more conical, and the last whorl more depressed, so much so as to give the periphery an obtusely angular appearance. The peristome is thin. Colour white or pale greenish yellow, frequently with a dorsal spiral red zone ; basal callus greenish yellow. 7. HELICINA FULGORA, Gould. Helicina fulgora, Gould, Proc. Bost. Soc. Nat. Hist. 1847, p. 201 ; Expl. Exp., Shells, p. 97, fig. 106 ; Pfeiffer, Mon. Pneum. i. p. 401 ; Gray, Cat. Phan. p. 293 ; H. & A. Adams, Gen. Moll. ii. p. 302 ; Mousson, Journ. de Conch. 18G5, p. 178, 1869, p. 356, 1870, p. 198 (var. expansa), 1871, p. 25 (var. diminutd); Pease, Proc. Zool. Soc. 1871, p. 476 ; Paetel, Cat. Conch, p. 125; Schmeltz, Cat. Mus. Godeff. v. p. 98. Dr. Gould's type specimens were obtained at Manna and Upolu, Samoa Islands. Mousson's variety expansa was found by Dr. Graffe at Kanathia aud Viti Levu. He also described the small var. diminuta from the Tonga Islands. Pfeiffer erroneously cites the Sandwich group as one of its localities. This species, which lives on the ground in forests, may be distinguished by its thin, smooth, shining shell, convexly conoid spire, angular and conspicuously carinated body-whorl. The peristome is thin and expanded, forming an angle at the point of union with the columella. Colour pale corneous, white, or light sulphur-yellow, with longitudinal flexuous reddish or white narrow stripes. Diam. 4 to 9 millim. 8. HELICINA MUSIVA, Gould. Helicina musiva, Gould, Proc. Bost.

Moll. ii. p. 302; Mousson, Journ. de Conch. 1865, p. 178 (var. uveana), 1869, p. 357, 1870, p. 202 (var. vitiana et subcarinata), 1871, |
