Bibliography. 
1853. In a paper *‘ On the Coal-measures of the South Joggins, Nova Scotia,”’ 
Sir W. J. Dawson at p. 39 figures two shells as Modiole (figs. 22 and 23), and 
two as Uniones (figs. 24 and 25), from these measures. No specific names. 
1862. Winchell described, in the volume of the ‘ Proceedings of the Academy 
of Natural Science of Philadelphia’ for 1862, p. 413, Cardinia complanata, C. 
aquimarginalis, said to be closely allied to C. robusta, and C. concentrica, from 
Carboniferous beds of the Marshall and Huron groups of Michigan. 
1864-5. Messrs. Meek and Worthen (‘“ Paleontology of the Upper Missouri,” 
part i, p. 34, ‘Smithsonian Contributions to Knowledge,’ No. 172) include 
Carbonicola (spelt Carbonocola) in the family Crassitellide, with Astarte, 
Crassatella, Cardita, &c., and a very large number of fossil genera of most 
diverse characters,—Venericardia, Pachydomus, Astartila, Astartella, Cardinia, 
Hippopodium, Pleurophorus, and various others. 
At p. 36. Anthracomya is included in the family Anatinidx, with Anatina, 
Thracia, Pandora, and Pholadomya, and other recent genera, and with the fossil 
genera Carcomya, Allorisma, Myciates, Arcomya, Cardiomorpha, Sedgwickia, 
Sanguinolites, and others. Such a group, with scarcely a character in common, . 
cannot be admitted for a moment. 
1875. Baily gives a figure of Carbonicola ovalis under the name Anthracosia 
centralis in his ‘ Figures of Characteristic British Fossils,’ p. 115, pl. xxxix, fig. 8, 
from the Coal-measures of Wednesbury, South Staffordshire. 
1878. Bigsby’s ‘ Thesaurus Devonico-Carboniferus’ gives lists of all the 
then known species of Devonian and Carboniferous Lamellibranch fossils. The 
following are from American Carboniferous strata (p. 296) : 
Anthracosia equimarginalis,! Winchell. Anthracosia concentrica,2 Winchell. 
— Antigonesensis, Dawson. — Sragilis (?), Cox. 
a Bradorica, Dawson. — nana, Owen.
