Show 308 MR. A. GARRETT ON THE TERRESTRIAL [Mar. 1, A thin, turbinate, conical, reddish horn-coloured species, with 6 angulate whorls which are spirally lineated with elevated lines, two on the body and one on the whorls of the spire so much larger than the others as to give the former a biangular, and the latter an angular outline. The basal keel is small. Length 5g millim. Mousson's figure is not very characteristic. The whorls are too much rounded, and do not exhibit the large spiral lines which modify the outlines of the shell. Mr. Schmeltz refers it with a doubt to the genus Garrettia ( = Diadema, Pease). An examination of the operculum would decide the question of its generic rank. 6. OMPHALOTROPIS COSTULATA, Mousson. Realia (Omphalotropis) costulata, Mousson, Journ. de Conch. 1870, p. 190, pl. 7. fig. 10 ; Pfeiffer, Mon. Pneum. iv. p. 233. Omphalotropis costulata, Paetel, Cat. Conch, p. 124. A few examples found beneath dead leaves at Vanua Balavo, where Dr. Graffe obtained the type specimens. A small, ovate, whitish horn-coloured species, 5| millim. long, with 6 convex whorls, and furnished with small, longitudinal, crowded riblets. The perforated base has a well-defined keel, and there is sometimes faint indication of a peripheral keel. 7. OMPHALOTROPIS SUBSOLUTA, Mousson. Realia (Omphalotropis) subsoluta, Mousson, Journ. de Conch. 1870, p. 192, pl. 7. fig. 12; Pfeiffer, Mon. Pneum. iv. p. 219. Omphalotropis subsoluta, Paetel, Cat. Conch, p. 124 ; Schmeltz, Cat. Mus. Godeff. v. p. 100. Discovered by Dr. Graffe at Oneata, one of the Windward Islands. A smooth, pale horn-coloured, turreted species, with 7\ convex whorls; the last one, which is slightly separated from the penultimate, is usually furnished with a filiform carina a little below the periphery. A similar remote keel circumscribes the basal perforation. The vertical aperture is about one fifth the length of the shell. Peristome porrected, continuous, and slightly patulous at the base. Length 10 millim. 8. OMPHALOTROPIS ZEBRIOLATA, Mousson. Omphalotropis zebriolata, Mousson, Journ. de Conch. 1865, p. 181, pl. 14. fig. 11, 1870, p. 193, 1873, p. 108; Pease, Journ. de Conch. 1869, p. 145; Proc. Zool. Soc. 1871, p. 476; Paetel, Cat. Conch, p. 124 ; Schmeltz, Cat. Mus. Godeff. v. p. 101. Realia (Omphalotropis) zebriolata, Mousson, Journ. de Conch. 1870, p. 193, 1871, p. 27; Pfeiffer, Mon. Pneum. iv. p. 225. Omphalotropis perforata, Mousson, Journ. de Conch. 1865, p. 182, pl. 14. fig. 12; Pease, Journ. de Conch. 1869, p. 145; Proc. Zool. Soc. 1871, p. 476; Paetel, Cat. Conch, p. 124; Schmeltz, Cat. Mus.
