Nucula, sp. ? (Sckizodus.) 



Anthracosia, new angular species. (Schizodus.) 



Posidonia Oibsoni. 



Solemya primseva. 

 Aviculopecfen. 



1891. In the ' Proceedings of the Academy of Natural Sciences of Philadelphia ' 

 for 1891, p. 242, is a second paper by C. R. Keyes, on " Fossil Faunas in Central 

 Iowa." Several Lamellibrancbs are enumerated from Carboniferous beds, but no 

 new forms are described. 



1892. In the ' Proceedings of the Royal Physical Society of Edinburgh,' 

 vol. xi, p. 244, is a paper by J. G. Goodchild, entitled " Notes on Carboniferous 

 Lamellibranchs," in which he confirms the fact that the Nuculoid shells from 

 Carboniferous beds possess a distinct cartilage-pit, and therefore cannot be 

 referred to Gtenodonta, Salter. He also points out the absence of a pallial sinus 

 in some of these shells. 



Another paper, at p. 245, in the same volume deals with the genus Allorisma, 

 a diagnosis of which is given, and it is stated that a pallial sinus is seen in at least 

 six species. 



1892. Professor W. Amalizky's work, " Ueber die Anthracosieu der Permfor- 

 mation Russlands," in ' Palasontographica,' Band xxxix, 1892, p. 125, ei seg., deals 

 only with fresh-water forms, which he classes under the following genera : 



Carbonicola, M'Coy. 

 Anthracosia, King. 

 Palceomutela, Amalizky. 



Oligodon, Amalizky. 

 Naiadites, Dawson. 



1892. Professor X. Stainier's paper, " Materiaux pour la flore et le faune du 

 houiller de Belgique," published in vol. xixof the 'Annales de laSociete Geologique 

 de Beige,' 1892, p. 333, gives tabular lists of the localities and horizons at which 

 fossil Lamellibranchs are found, many marine forms being included. A second 

 note on the " Faune du Houiller " was issued in the volume for 1892-3, tome xx, 

 p. 43 ; and a third note was published in the ' Bulletin Societe Beige de Geologie, 

 &c.,' tome vii, 1893, p. 135, with further details of the occurrence of Carboniferous 

 Lamellibranchiata in the Belgian coal-bearing strata. 



1894. In a paper, " Ueber die systematische Stellung der Trigoniden und 

 die Abstammung der Nayaden," by von S. Frh. V. Wohrman, in the ' Jahrbuch 

 der k.-k. geologischen Reichsanstalt,' Band xliii, for 1893, the affinities of 

 Schizodtis (p. 7), Palseomutela (p. 16), and Palseoneilo, p. 18 (Tellinomya), are 

 discussed. 



1893. Vol. vii, ' Report of the Geological Survey of Ohio,' contains, chap, iii, 

 a section on the " Palfeontology of Ohio," by R. P. Whitfield. Pinna Maxvillensh.^ 

 Allorisma Anclrewsi, and Allorisma Maxvillensis are here figured and redescribed.
