1890. Mr. Charles Roeder, in “‘ Notes on the Upper Coal-measures of Slade 
Lane, Burnage ” (‘ Manchester Geol. Soc. Trans,’ vol. xxi, p. 114, read December, 
1890), gives a full description of these beds, many of which contain mollusca. 
With one or two exceptions, however, he gives no specific names. 
1892. In the same volume (vol. xxi, p. 364, read December 8th, 1891) is a 
paper by Mr. George Wild, on ‘‘ The Lower Coal-measures of Lancashire,” of 
great value. He figures (pl. ui, fig. 7) a new angular species of Anthracosia, 
which turns out, however, to be Schizodus carbonarius. 
He also mentions in his Catalogue at the end of his paper, Anthracosia, sp., 
hike Sanguinolites, from the Mountain-mine roof, Shaw, near Oldham; and 
Anthracosia aquilina, from a bed thirteen yards below the same seam at Rishton. 
1892. M. X. Stainier gives (in ‘ Annales Soc. Géol. de Belg.,’ vol. xix, p. 2) a 
list of shells, referred to by previous authors, from beds in Belgium, with a few 
additional localities from his own knowledge. 
1892. In 1892 appeared the work of Professor W. Amalizky, ‘‘ Ueber die 
Anthracosien der Permformation Russlands,’! in which he reviews most of the 
literature bearing on the generic affinity of the Unio-like forms of the Coal- 
measures. He erects the group into a family, under the name of Anthracoside, 
and divides the family into five genera: 
Anthracosia, King. Cardinal teeth only. 
Carbonicola, M‘Coy. Cardinal and lateral teeth. 
Najadites, Dawson. Edentulous forms. 
Paleomutela. 
Olijodon: ‘ New multidentate forms.
