OLDROID, I. S. 1920. New species of west cooast shells. The Nautilus, 33 (4): 135-136, pl. 4. [p. 135, pl. 4, figs. 3-4]
«Pecten kincaidi n. sp. Plate IV, figs. 3, 4.
Shell subcircular, the height and length being nearly equal; equivalve, both valves slightly convex; ears as in P. islandicus; base evenly rounded; color yellowish-white with reddish-brown markings. Left valve with 28 narrow round-topped imbricated ribs, and very faint intercalaries, the interspaces wider. Right valve with 25 broader flat-topped ribs, some of which are divided toward the margin. Anterior ear (the larger) with 7 ribs, the posterior ear with 5 ribs. This species resembles P. jordani Arnold, but the valves do not tend to contract suddenly at the basal margin as in P. jordani, and the right ear is larger. The ribs on the right valve of jordani are all divided from near the umbones. One fine specimen (the type) living was obtained in July, 1919, and one was taken in July, 1918, but is much thicker shell, a little larger than the type. Named in honor of Prof. Trevor Kincaid, of the Univ. of Washington, to whom we owe so much good material. Type is in Oldroyd Coll., Stanford University, No. 89.» IDA SHEPARD OLDROID, 1920
