«Species 170. (Mus. Cuming.)*
PECTEN LENTIGINOSUS. Pect. testâ trigono-ovatâ, subflabelliformi, compressâ, aequilaterali, inaequivalvi, valvâ sinistrâ costis lirisque numerosis grandibus et parvis, profusè noduloso-squamatis, subirregulariter radiatâ, valvâ dextâa ecostatâ, undique liratâ, squamis brevibus, abruptè nodulosis; purpurascente-albâ, intensè purpureo hic illic tinctâ et maculatâ; auriculis valdè inaequalibus, flexuosis.
THE SPECKLED PECTEN. Shell triangularly ovate, somewhat fan-shaped, compressed, equilateral, equivalve, left valve somewhat irregularly rayed with numerous large and small ribs and ridges, profusely nodulously scaled, right valve not ribbed, ridged throughout, with the scales short and abruptly nodulous; purplish-white, stained and spotted here and there with deep purple; ears very unequal, flexuous.
Hab. ——? A very characteristic new species, easily recognizable by the details above noted.» * "ERRATA. Species 170. For P. lentiginosus read P. lemniscatus."

«Distribution: Western Indian Ocean, from Malagasy Republic and the Mascarenes to eastern South Africa, as far south as southern Natal.
Habitat: Living byssally attached to rocks or corals and between coral rubble or sediments on sandy or muddy sand bottoms at littoral to sublittoral depths.
Remarks: C. liltvedi is here synonymised with Pecten lemniscatus, as it agrees in all aspects with the holotype of that. The most similar species is Laevichlamys rubromaculata (G. B. Sowerby 2nd, 1842) from the NW Indian Ocean and Red Sea. This differs from L. lemniscata mainly in its more delicate and weaker sculpture and microsculpture, and in its coloration of red, orange or brown maculations between primary radial ribs on a creamy or yellow background (it is rarely uniformly coloured).
In the literature the name ‘P. lemniscatus’ has been frequently misapplied; thus, records under this name by Dautzenberg & Bavay (1912: 13), Kira (1962: 137), Habe (1981: 63), Abbott & Dance (1982: 312), Rombouts (1991: 15) and Bernard et al. (1993: 48) were based on various Scaeochlamys species. Smith’s (1885: 298) record of ‘Pecten lemniscatus’ from the Philippines is also doubtful, as material from that region has a shagreened microsculpture, which is absent in the holotype of P. lemniscatus, and is in fact lacking in this species throughout its ontogeny.» DIJKSTRA, H.

«Shell triangularly ovate, somewhat fan-shaped, compressed, equilateral, equivalve. Left valve somewhat irregularly rayed with numerous large and smallribs and ridges, with profuse nodulose scales. Right valve not ribbed, but ridged throughout with short and abruptly nodulose scales. Ears very unequal. Purplish-white, stained and spotted with deep purple, also other color variations. Moderately common, living under stones at about 12 m. Max. stze: 43 mm.»

«Other species.— [Laevichlamys] In addition to the type species, extant species included in the new genus are as follows: Pecten irregularis G.B. Sowerby II, 1842; P. lemniscatus Reeve, 1853; P. limatulus Reeve, 1853; P. mollitus Reeve, 1853; P. ruschenbergeri Tryon, 1869; Ostrea squamosa Gmelin, 1791; and Chlamys wilhelminae Bavay, 1904. All of these live in the Indo-Pacific region.
There is still much to learn about the fossil record of this genus, but two extinct species are included thus far: Pecten (Chlamys) lauensis Ladd in Ladd and Hoffmeister, 1945, Fiji, late Miocene or Pliocene; P. shirahamaensis Nomura and Niino, 1932, Japan, Early Pliocene (Masuda, 1962, p. 185).» WALLER, T.

«C. Iemniscata (Reeve), a form now living in the western part of the Indian Ocean, and often collected off Mauritius, is very closely allied to C. odontota, and may prove to be the same species; Dautzenberg and Bavay consider it to be a varietal form of C. irregularis (Sowerby).»
