COLLINGE, F.Z.S., Assistant Lecturer aud Demoustrator in Zoology and Comparative Anatomy, Mason College, Birmingham. [Received June 2, 1897.] (Plate XLIV.) The two new species of Parmarion here described were collected by Mr. A. H. Everett at Lombok, Borneo, and forwarded to Mr. Edgar A. Smith, of the British Museum, who has very kindly placed the same in my hands for identification. The perfect specimens and dissected parts have been placed in the collection of the British Museum, South Kensington. In 1895 I described, in conjunction with Lieut.-Col. H. H. Godwin-Austen, F.E.S.1, a series of forms from Borneo allied to those now received, and I am very pleased to be able to examine further material from this interesting region. In the above-mentioned paper we expressed the hope that further material would be obtained from Borneo, in order that our knowledge of the genera Parmarion, Micropannarion, Damagantia, &c, might be increased. One of the species here described, P. intermedium, may, I think, be regarded as a connecting link between the genus Parmarion and Micropannarion. PARMARION EVERETTI, n. sp. Hab. Lombok (2000 ft.), Borneo (A. H. Everett). Shell oval in form, almost flat, amber-coloured; lines of growth well marked, apex obscure, borders membranaceous, hidden by the mantle. Major diam. 16 millim.; minor diam. 12 millim. Animal (Pl. XLIV. fig. 1) greenish grey, head dark green with light brown portion in mid-dorsal line; sides of head yellow. Mantle-lobes yellowish brown, with fine dark blue speckles and blotches. Commencing beneath the visceral mass, where the dorsum is flat and very pale yellow in colour, are two dark brown bands, shading posteriorly to black, which pass backwards and slightly downwards, terminating at each side of the caudal mucous pore ; posteriorly the sides of the body are speckled with black. Bugae not prominent. Foot-fringe yellow, with somewhat broad chocolate-coloured liueoles, narrowing and becoming lighter in tbe anterior region. Foot-sole divided into median and lateral planes, the former yellow in colour, the latter greenish grey. Caudal mucous pore a vertical slit, not extending to the foot-sole (Pl. XLIV. fig. 2). Length (in alcohol) 42 millim. I have much pleasure in associating with this species the name of Mr. A. H. Everett. 1 " O n the Structure and Affinities of some new Species of Mollusca from Borneo," Proc. Zool. Soc. 1895, pp. 241-250, pis. xi.-xiv. |
