Graffe subsequently discovered some specimens of Trochomorpha in the interior of Viti Levu, which Mousson (in Journ. de Conch. 1870, p. 122) referred to his T. transarata, adding additional characters and giving a good figure of the same. On the same page he describes the var. depresso-striata, which latter is probably distinct and = T. fessonia, Angas. Unfortunately I lost all my Kantavu specimens of the latter species when shipwrecked, and have only a single dead example of T. transarata from Lomaloma, which exactly coincides with Mousson's original description, and agrees with his figure of a Viti Levu shell. Mr. Brazier (in P. Z. S. 1871, p. 322) adds T. transarata to the synonymy of fessonia. Schmeltz (in Cat. Mus. Godeff. v. p. 94, sp. 5939) quotes Mousson's var. T. depresso-striata as = fessonia, and, judging from the Museum numbers, he does not include the type, which is no. 5235 (see Cat. no. iv. p. 73), in the synonymy. Its small size, depressed conical form, rough irregular plicate striae, brownish horn-colour with interrupted radiating pale stripes, elevated spire, slightly convex base, and small umbilicus are its most prominent characters. 9. TROCHOMORPHA ACCURATA. Trochomorpha (Discus) accurata, Mousson, Journ. de Conch. 1870, p. 120, pl. 7. fig. 2. Nanina (Microcystis) accurata, Paetel, Cat. Conch, p. 84. Helix accurata, Pfeiffer, Mon. Hel. vii. p. 290. A very rare species, found by Dr. Graffe iu rocks at Veria, in the interior of Viti Levu. It has the spire more elevated than T. transarata, a greenish-violet colour, the striae strong and irregular, the umbilicus small; whorls 7, the last one acutely carinated with a compressed, white keel. Major diam. 14, height 12 millim. 10. TROCHOMORPHA CORALLINA. Trochomorpha (Discus) ludersi, var. corallina, Mousson, Journ. de Conch. 1870, p. 123. I found a few examples of this species on elevated coralline reefs in forests on Vanua Balavo, and took a large number in similar stations on Mango Island. Dr. Graffe found it on coral-rocks on Malatta and Tutuna, the latter one of the northern islands of the Tonga group. It may be described as follows:- Shell umbilicated, sublenticular, solid, finely and obliquely striated, fulvous horn-colour, rarely whitish, with or without a marginal dorsal and basal dark fuscous band; spire convexly conoid, obtuse; suture depressedly margined above ; whorls 5|, slightly convex, slowly and regularly increasing, the last one not descending in front, acutely carinated ; base convex ; umbilicus small, about one seventh the greater diameter of the shell; aperture diagonal, subrhomboid- |
