«248. PECTEN rubidus, (Plate XVII, fig. 5) Testa subtrigono-orbiculari, inaequaliter duploconvexa, inaequiauriculata. subtenui; valva sinistra convexa, costis parvis numerosissimis, serratis, in fasciculos duarum triumve alternate aggregatis, rufis, interstitiis pallescentibus; valva dextra subconvexa, albida, costis majusculis, aggregatis; auriculis sulcatis, postica parva., obliqua; intus alba.
Inhab. Alashka, North-west America. At a depth of thirty-three fathoms. This species has both close geographic and structural relations with P. icelandicus. Four specimens were obtained at the same depth, and they agree in the different state of convexity of the valves, their tumidness, the somewhat elegant and methodical clustering of the small ribs, and the very small and oblique posterior auricle. The colour, though at first apparently of an uniform rose, is deeper on the ribs than in the interspaces, with concentric bands of the same. None of the specimens approach in size P. icelandicus.» RICHARD BRINSLEY HINDS, 1845

«Chlamys rubida ( = Pecten hindsii Carpenter, 1864; see Grau (1959», once considered by some authors to be a subspecies of C. islandica, has in recent years been treated as a separate species (Grau, 1959; MacNeil, 1967; Moore, 1984). Its southern limit in the eastern Pacific is off San Diego, California, at great depths (USNM 150204, 822 fathoms), but its main distribution is to the north, ranging from off Monterey, California, to the Aleutian Islands and Pribiloff Islands in the southern Bering Sea (Grau, 1959; Bernard, 1983). On the Asiatic side of the North Pacific, the species occurs in the weste rn Bering Sea from Anadyrskiy Bay southward along the east side of the Kamchatka Peninsula and the Kurile Island s to the Pacific coast of Japan as far south as 42° N (Grau (1959), citing Kuroda and Habe (1952) and Kira (1955)). In terms of shell morphology (PI. 1, Figs. 14, 17), this species is the closest to Atlantic C. islandica of any of the Pacific species, differing from the Atlantic species in having a short erhinge with a shallower byssal notch, a more circular disk, and fine ribs that branch and intercalate consistently in later ontogeny to produce regular fascicles. C. rubida displays considerable variation throughout its range in the eastern North Pacific, and there seems to be little value in applying subspecies names to local populations. The latest subspecies to be named, C. rubida asiatica Skarlato, 1981 (de scribed by Skarlato as C. hindsii asiatica), introduced for populations along the Asiatic side of the North Pacific, does not appear to have any morphological features that are outside the range of variation of populations in North American waters.»

«Additional description: Adult specimens averaging 50 millimeters in height and slightly higher than long; left valve more convex than right, and hinge line about half length of disk. Right valve with extremely variable rib structure; 21 to 28 low, smooth, broad and rather flat primary ribs, becoming dichotomous at about 10 to 15 mm from hinge line and occasionally imbricated near ventral margin; ribs frequently narrower, obscurely fasciculated and almost entirely imbricated. Riblets often develop in interspaces, usually starting at 15 to 20 mm from hinge margin and occasionally imbricated. lnterspaces narrower than ribs and with minute reticulations present in either upper or lower portion or throughout. Anterior auricle large and with 6 or 7 riblets having fine concentric imbrications; byssal notch prominent, and ctenolium of 5 to 7 teeth. Posterior auricle small, with 8 to 11 small spinose riblets; hinge margin tapering gently downward from beak. Left valve also variable in rib structure; primary ribs simple at first, later fasciculated; each fascicle consisting of three (occasionally two) imbricated ridges, often worn smooth at maturity; imbricated secondary rib usually present in center of each interspace, often flanked by two very small rows of spines. Interspaces wider than ribs and minutely reticulated from umbo to center of disk. Anterior auricle large and with moderately deep byssal notch; 10 to 12 small riblets with nearly as many intercalaries, all imbricated. Posterior auricle small, hinge margin tapered as in right valve; 10 to 15 fine imbricated riblcts. Interior glossy white or yellow-white; margin delicately fluted. External color ranging through shades of red, pink, lavender, purple, orange and yellow; right valve much paler than left; occasional specimens mottled, others all white.
Remarks: It is unfortunate that the specific name hindsii, by which this familiar species has been known for nearly a hundred years, must now become a synonym. However, in Opinion 456, 1957, the International Commission ruled that Martyn's often-disputed "Universal Conchologist" was not consistently binomial and rejected it, making all the names published therein unavailable; thus rubidus Hinds is now valid for this species, having priority over hindsii Carpenter. Geographical range: Bering Sea to Monterey, California. Also Pacific coast of Japan, as far south as 42° N. Geochronological range: Pliocene, Pleistocene, Recent. Bathymetric range: Just below low tide to 100 fathoms, possibly deeper. Ecological data: Usually found off rocky shores. Shell usually encased in one of two species of symbiotic sponge: most often Ectyodoryx (formerly Myxilla) parasitica (Lambe), but occasionally Mycale adherens Lambe. Both species are said to live only on Chlamys rubida, C. rubida jordani, C. hastata, C. hastata hericia and C. hastata pugetensis, and to be the only species of sponge so restricted. Large barnacles, up to 25 or 30 mm in altitude, are often attached.» GRAU,

«Remarks: Arnold's criteria for Pecten (Chlamys) jordani are not all stable features: the ribs of the left valve are occasionally rather broad and flattened, the imbricating sculpture (but not the reticulating) is often nearly absent, the basal margins seldom contracted or compressed.
Various criteria have been suggested for separating Pecten hindsii kincaidi from P. hindsii jordani, but a long series of specimens clearly shows the presence of only a single subspecies. From Chlamys rubida this subspecies is distinguished by the following features: smaller size when adult, right valve not becoming dichotomous until shell attains height of about 30 mm, ribs of left valve smoother and not fasciculate, reticulate sculpture more prominent and covering entire surface of both valves, and coloring always mottled to some degree. Geographical range: Gulf of Alaska to Puget Sound. Geochronological range: Pliocene, Pleistocene, Recent. Bathimetric range: 25 to 60 fathoms. Ecological data: Found off rocky shores, often encased in same species of sponge as Chlamys rubida.» GRAU,
