Paraparmarion elongatus Collinge, 1902
“This is one of those small, puzzling, Parmarion-like molluscs, common to the Indian and Malayan faunas. I have compared this interesting specimen with a large number of small Parmarion-like molluscs in my collection, from Java, Borneo and India, which at present are unnamed, and also with immature specimens of Parmarion, but can find nothing at all like it. The well-developed shell and the degenerate mantle at once characterise this form, and it seems desirable that it should be named, if for no other reason than that of directing attention to these diminutive species. Until the internal structure is made known it is difficult to say its true position is, but judging by the external features, this genus may possibly supply a link between the genus Damayantia of Issel and Parmarion of Fisher.” (Collinge, 1902)
Collinge (1902) original descriptions on Paraparmarion elongatus – “Animal dark reddish-brown, head and tentacles bluish, mantle degenerate, rising upon the shell on the right side only, as a dark brown, wing-like lobe, covering the apex of the shell. Rugae scarcely visible, small and flat. Peripodial groove faintly marked. Caudal mucous pore very small, not extending to the foot-sole. Foot-frige reddish-brown. Foot-sole reddish-brown, divided into narrow median and broad lateral planes. Shell yellow, thin, membranaceous; whorls 3, last whorl large and globose.”
Paraparmarion elongatus – “Length (in alcohol) 12 millim.” (Collinge, 1902)
Type locality – “Gunong Inas, 3500 ft. State of Perak” (Collinge, 1902)
