1869. In the ' Proceedings of the Academy of Natural Science of Philadelphia ' 

 for 1869 is a paper, " Description of New Carboniferous Fossils from the Western 

 States," by Meek and Worthen, pp. 70, 71. In this contribution only two 

 Carboniferous Lamellibranchs are described, both new, one belonging to a new 

 genus, Ghsenocardia, G. ovata and Allorisma costata. The diagnosis of the genus 

 Ghaenocardia is given, and at p. 72 the generic name Prothyris is proposed for a shell. 



1869-87. The first edition of the ' Greological Survey Memoir' on the Lime- 

 stone District of Derbyshire was published in 1869. It contains a list of fossils

1870. Messrs. Meek and Worthen presented a paper in April, 1870, to the 

 Academy of Natural Sciences of Philadelphia, published in the volume of ' Proceed- 

 ings ' for that year, pp. 22, &c., entitled " Descriptions of New Species and Genera 

 of Fossils from the Palaeozoic Rocks of the Western States." Two new genera 

 of Lamellibranchs, Garbonarca and Glinopistha, are described, and the follow- 

 ing species enumerated from Carboniferous strata (no figures are given) : 



Monotis ? gregaria. 

 Aviculopecten spinuliferus.

 is a paper by Mr. R. Craig (read January 9th, 1869) on " The Carboniferous 

 Basin of Dairy," with lists and localities of fossils. 



1871. Two papers by Meek occur in the ' Proceedings of the Academy of
