Pecten (Chlamys) waylandi, new species.
(Plate 7, Figures 4 a, b.) «The following is a description of this species:
Shell medium-sized, nearly equilateral, equivalve, with about 30 low ribs with equal interspaces becoming obsolete towards the depressed submargins; posterior ears small, oblique, with 4 or 5 faint radial riblets; anterior ears much larger, with about 12 faint riblets on left ear and 5 or 6 somewhat coarser riblets on right ear; byssal notch. about one-half the length of the ear; inner margin fluted in accordance with the external ribbing in channels which probably extend well towards the center of the disk. Alt., 32.3 mm.; lat., 29 mm.; diam., 12.5 mm. Although the single specimen upon which this species is founded has lost so much of the external part of the shell that it is impossible to make out the details of sculpture, the ears, as well as the outline and major sculpture of the shell, are so well preserved that it seems worth while to describe it. The species is not apt to be confused with any other of this region. It is named in honor of Dr. T. Wayland Vaughan. Locality.— Santiago, Cuba, station 3440, Vaughan. Geologic horizon.— Oligocene. Type.— U. S. Nat. Mus. No. 167121.» CHARLES WYTHE COOKE, 1919
