The following have been received since the first sheet was 

 printed :

 Silurian Rocks. — |Geol. Surv. Canada.

 Acad. Nat. Sci. Phil. 



1865 — Id. Descriptions of New Species of Crinoidea from the Palaeozoic 

 Rocks of Illinois and some of the adjoining States. — [Ibid. 



1865 — Id. Descriptions of New Crinoidea, &c, from the Carboniferous

 lished since the earlier sheets of this Catalogue were print- 

 ed. These are now added. 



GENUS ACTINOCRINUS.

 Girardeau, Missouri. 



GENUS CYATHOCRINUS. 

 C. arboreus. Id. ibid. p. 160. — Arch. — Crawfordsville, Indiana. 

 C. crassibrachiatus. [This species was by mistake omitted in its 



proper place among the Cyathocrini and transferred to p. 



360, where the specific name wrongly stands for a Genus.]

 Billings, 1857. Geol. Rep. Canada, p. 342.— 1865. Pal. 



* It is quite possible that this species is not distinct from A. conicus of 

 Lyon & Casseday, as has been suggested by Meek & Worthen in their 

 paper.
