 following new species are described : 



Axinus (^ScMzodus) ovatus.

1859. McChesney issued a small work, entitled ' Descriptions of New Species 

 of Fossils from the Paljeozoic Rocks of the Western States,' in 1 859. The volume

Allorisma sinuata. 

 — clavata. 

 Astartella varica. 

 Leda f/ihhosa. 

 — Oweni. 



Leda polita. 

 Nucula parva. 



— cylindrica. 

 Edmondia concentrica. 

 Myalina Sivallovi. 



1859-60. In the ' Proceedings of the Academy of Natural Sciences of Phila- 

 delphia,' for 1859, published 1860, W. M. Gabb, in a short paper, " Description of 

 Two New Species of Carboniferous Fossils brought from Fort Belknap, Texas, 

 by Dr. Morrey, describes Myalina deltoidea and Posidonia Moorei. 



1860. The Lethsea Bossica of Eichwald came out in parts between the years 

 1853 and 1869. The portion containing descriptions of Carboniferous remains, 

 being the 2nd and 3rd parts of the ' Periode ancienne,' is dated 1860. A few 

 new species are described and figured in this work, with drawings of many of 

 this author's species previously published in the ' Bulletin Soc. Nat. de Moscow,' 

 and other works mentioned above. 



^ Bigsby quotes, Pinna Adamsii, Astartella concentrica, and Leda Knoxensis from Carboniferous 

 beds, as described by McChesney, but I cannot find the publication.
