" Shell yellow, convex externally, concave internally, like a halt eggshell."-Deshayes, from Ferussac's figure. This is very unlike th Inutile Appendix to Adams's Gen. Moll. p. 640, it is stated that Dr Gray, in a communication to the author, proposed that these two last "species should be placed in another new genus, Rigasia ; and on the same page G. hookeri is put into Cryptella, a Canary-Island form with which it can have no possible affinity. PARMARION, Fischer1. Dr. Semper, in his fine work, Reis. Arch. Phil. p. 9, places in Parmarion two specimens, pupillaris, Humbert (problematica, Fer..) from Java, and extraneus, Fer., obtained through Herr Pierre, and taken by him in Calcutta. I am in great doubts as to the identification of the laUer species, which Semper figures on plate i. fig. 5. Mr. Nevill thinks it is Helix bensoni of Lower Bengal. No forms like the Khasi-Hill G. hookeri have been taken in Calcutta. If it was found in the Botanical Gardens there, it may have been brought from up the country in baskets of plants. Several imported species have been in this way introduced there from time to time ; and some may have become established. I do not think myself it is H. bensoni ; the shell is too much covered with the mantle, especially for a spirit-specimen. In Nevill's Hand-list of the Indian Museum, Calcutta, p. 13 (1878), in Parmarion he includes two species of typical Girasia from the Khasi Hills, croceus and brunneus, and creates a new subgenus, Austenia (type Vitrina gigas of Benson, from the Khasi Hills), to include all those species with better-developed shells, which could not be placed in Helicarion, and which I had pointed out were different from Theobald's slug-like forms known to us then as Hoplites. He included in this group Hoplites magnificus, resplendens, peguensis, solidus, auriformis, heteroconcha, and two others unnamed from Darjiling- I had myself brought home from India a good many specimens in spirit; and I have lately received from Mr. Ogle, of the Topographical Survey, to whom my very best thanks are due, another lot 1 PARMARION, Fischer, Actes Soc. Linn. Bordeaux, 1855. (The paper bears date June 1855, the part 15th March, 1856; so that Mr. Gray's title has priority.) Fischer places in it the following species :- infumatus, Fer. (Gray, Fig. Moll, plate 286. fig 1). Hab.? (Placed hi Brusia, by Gray.) extraneus, Fer. (Gray, Fig. Moll, plate 286. fig. 2). Hab. ? rangianus, Fer. Bourbon and Madagascar. (Placed in Brusia ? by Gray.) problcmalicus, F£r. (Gray, Fig. Moll, plate 286, fig. 4). Hab. ? From the drawing of infumatus, by Ferussac, one would be led to suppose that the shell is very rudimentary, and entirely concealed by the mantle-lobes. Unfortunately the habitat of this species and extraneus is unknown. I, how- |
