This species has a small left shell-lobe, shaped as in Cyclopias (see fig. 4, pi. xxxi., Land and Freshwater Moll. Ind.). Jaw with prominent central projection. It therefore does not, so far as the mantle is concerned, agree with typical Macrochlamys. Better spirit-specimens are required for examination. 4. MACROCHLAMYS CHOINIX, var. GIGANTEA (p. 441). In a M S . copy of Nevill's ' Hand-list' M. gigantea is catalogued as a variety of choinix-" ? a distinct species. Collected by F. A. de Roepstorff, Esq. Diam. 19-25; alt. 10*25 mm." I have not seen an example of this species. 6. MACROCHLAMYS WOODMASONIANA, Nevill MS. (p. 441). This species is no. 33 of Nevill's ' Hand-list' (p. 23). The type is in the Indian Museum, Calcutta, obtained by Mr. J. Wood- Mason. 7. MACROCHLAMYS HONESTA, var. TENUIOR (p. 441). This species is recorded in Nevill's • Hand-list' (p. 24) as the Moulmein variety; and tbis is the typical locality, and collected there by Stoliczka and Theobald. It is also recorded from Preparis Island, the most northerly of the Andaman Group, from the collection of Ferd. Stoliczka. I have in my own collection three specimens given me by Stoliczka, undoubtedly a variety of honesta, but the locality marked on the label is " Nicobar ? " ; so I refrain from describing it at present. 8. MACROCHLAMYS FORDIANA, G.-A. (p. 441). This species is no. 39 of Nevill's ' Hand-list'; it was unnamed when the catalogue was published. In his MS. catalogue Nevill has entered it as fordiana in ink, and microsculpta in pencil. Four specimens collected by Colonel Ford are the types in the Indian Museum ; six specimens are recorded from Mr. de Koepstorff. I adopted the title fordiana, though I find microsculpta on labels iu de Koepstorff's shells that have come to me. This species was described by me in the ' Annals and Magazine of Natural History' (ser. 6, ii. p. 57, 1888). 9. MACROCHLAMYS AULOPSIS (p. 441). Nanina aulopsis, Bs. Thalassia in Nomencl. This is a true Macrochlamys. The right shell-lobe is well developed, the left was not well made out. The odontophore is similar to that of the above genus, the formula being 2 0 - 8 - 1 - 8 - 2 0 about. |
