1926 Chlamys keiloriana Crespin, 1926
«Description of Holotype (Cast).— Left valve of shell only is present, and is probably the more convex. Thirty-eight ribs are present, which may reach forty in complete specimen. Ribs closely scaly, squamation depressed. Furrows flattened, and smooth and of equal space to the ribs. Ears unequal in size and scaly.
Dimensions.— Greatest length of posterior region, circ. 22 mm. Height, circ. 21 mm. Depth in median area, circ. 2 mm. Observations.— This shell belongs to the same group as C. antiaustralis, and seems to foreshadow the later forms of that type, including C. asperrima. The difference lies in the transverse squamation of the present form. In C. antiaustralis the ribs are flanked by narrower lateral riblets, which are scaly. The main ribs are far apart. The ribs in C. keiloriana are much closer together, and more, numerous. The squamation is more erect in C. antiaustralis and C. asperrima. In the former there are 25 ribs, in the latter (Victorian example), 22-24, and in C. keiloriana, 28-40. The nearest associate appears to be a species of Chlamys yet to be described from Grice’s Creek, in the Nat. Mus. Coll. Occurrence.— Ironstone Beds, Green Gully, Keilor, Outcrop 2. Age.— Janjukian.» IRENE CRESPIN, 1926
