Page 430. The species described as Zaphrentis inequalis may be 

 stricken Out. Subsequent examination of the specimen described 

 has shown that it belongs to the Hudson Kiver Group, and is the 

 Palceophyllum divaricans of Nicholson. 



Page 438. Zaphrentis inclinata is equivalent to Cyathopliyllum agus- 

 tatum. The specimen is from the Niagara Group of Kentucky. 



Page 407. Only eight plates are here given to accompany the paper 

 on the Fossil Corals. It is intended, at a future date, to repub- 

 lish this paper with illustrations of all the species. 



Page 465. It was originally intended to publish the complete me- 

 moir on the Fossil Reticulate Sponges; but the exigencies of pub- 

 lication have necessitated the presentation of the present abstract. 

 As soon as the drawings and lithography can be completed, the 

 entire memoir will be published as a bulletin of the State Museum. 



The document edition of seven hundred copies of the Thirty-fifth 

 Report of the State Museum, has been issued without the seven pages 

 properly following p. 406 and marked 406, a etc., though the whole 

 was in type at the time. The plates, 3-13, in the same volume, were 

 printed without the knowledge of the author or the Director of the 

 Museum, no proofs having been submitted to either of them.
