Not Pecten digitatum Perry, Conch., April, 1811, no. 2 on Expl. to pl. 55, pl. 55, fig.2. " A native of Amboyna and the Eastern Seas." Range: Guayaquil, Ecuador (Hinds; Reeve); probably Panama (Zetek). This species is not present in the collection made by the Templeton Crocker Expedition. The valves of the species are said to be very similar and are ornamented by nine rounded, grooved ribs. Dall [11] has mentioned that probably the species is only a young specimen of P. subnodosus Sowerby. A comparison of young specimens of P. subnodosus Sowerby with Hinds' figure of P. "digitatus," however, indicates that Sowerby's species has a very much larger anterior ear on the right valve and the shell is rounder in outline. Zetek in 1918 cited the species as one which probably occurs at Panama. Dautzenberg and Bavay [12] have pointed out the great resemblance between P. digitatus Hinds and P. vexillus Reeve [13]. The only differences noticed by them, in the two species, were the slightly less height of the shell, and the presence of nine ribs in Hinds' species rather than ten in P. vexillus. Possibly the locality "Bay of Guayaquil," given by Hinds for P. digitatus, is incorrect, although that is not definitely known. P. vexillus Reeve is known from New Caledonia, Nouméa, Island of Nou, Lifou, Madagascar, and the Philippine Islands. Dautzenberg and Bavay pointed out that P. distans Reeve (not Lamarck), which was renamed P. janus Montrouzier [14] (not Münster), can be considered to be a synonym of. P. vexillus Reeve. The true P. distans of Lamarck [15] is considered to be a variety of. P. glaber Linnaeus, a Mediterranean species. The name Pecten digitatus Hinds, is preoccupied by the earlier usage by Perry. In view of the conflicting evidence regarding this form, the name zeteki is substituted for the species described by Hinds. Possibly this species could be included in the subgenus Decadopecten Rüppell in Sowerby.» [11] Dall, W. H., Nautilus, vol 27, no, 11, March, 1914, p. 122. [12] Dautzenberg, P., & A.
