Griffin & Nielsen (2008): TYPE MATERIAL. Lectotype: NHM-L27960, a left valve, less complete than suggested by the figure (Sowerby 1846, pl. 3, fig. 33), with a fragment missing from the antero-ventral margin, with two small oysters attached to the disc on the postero-dorsal margin, and with the anterior margin of the anterior auricle sloping strongly forward and almost completely straight, from San José; paralectotype: NHM-L27983, a juvenile right valve from San José; paralecotype: NHM-L27982, a large (height 115 mm, width, 120 mm), complete and well preserved right valve, with the umbo and auricles a little hidden in the soft fawn-weathered sandstone, from San José. The identity of this specimen is doubtful but it certainly belongs in a different genus. REMARKS. Del Río (1992, text fig. 7) illustrated a cast of the left valve labeled NHM-L27960, which she referred to as the “holotype”. Apparently she was unaware of the existence of the other syntypes (see del Río 1992, p. 26). Sowerby’s original description does not clearly imply that there was more than one specimen. Therefore, this “designation by inference of holotype” is valid according to Article 74.6 of the ICZN (1999). |
