«Argopecten e. darlingtonensis (Dall) was characterized by radial threads towards the margin of the disk (plate 9: figure 1), along with 21 to24 well-marked, angular plicae. However, in comparing the suite of type material of A. e. darlingtonensis with population samples from Suffolk, Virginia, the type area for A. e. eboreus, the specimens from the Suffolk area also have marginal threads on many specimens along with a similar number and character of the plicae. On these characteristics and a general overall morphologic similarity, it would seem that these two subspecies, at least from their tvpe areas, are synonymous. A variety of forms are labeled A. e. darlingtonensis in the USNM collections, and some of these undoubtedly belong to other members of the A. eboreus complex. Mansfield (1936:184) placed A. e. darlingtonensis in the phylogenetic development of A. eboreus as a time equivalent subspecies to A. eboreus eboreus, and leading to A. e. solarioides, but it is uncertain what specimens he was considering. The specimen illustrated by Mansfield (1932, pl. 12: fig. 1) as A. e. darlingtonensis from the Pliocene of Florida appears to be related to A. e. solarioides. It would be difficult, however, to place this specimen within the variation found in the type suite and other samples from South Carolina.»
