APPENDIX 



In justice to Mr. Stewart, it should be said that his absence 

 in the field during the printing of the foregoing paper has 

 made it impossible for him to see the proof. Its correction, 

 therefore, has devolved wholly upon myself, and I cannot hope 

 to have done as well as would have the author. While in the 

 printer's hands an important paper on the Kansas Cretaceous 

 fishes was received from its author, Mr. F. B. Loornis,* too 

 late to be recognized in the text. A brief review of this article 

 is given below by Mr. Stewart, and the present writer has added 

 thereto a list of the species and genera treated by Mr. Loomis 

 in systematic sequence. — S. W. Willistox. 



A recent article on the Kansas Cretaceous fishes, by Mr. 

 F. B. Loomis.* reaches me while engaged in field-work, where 

 I do not have access to the literature or the manuscript of 

 the foregoing article on the Cretaceous fishes of Kansas, and 

 while the work itself was rapidly going through the press. I 

 can, therefore, make only the briefest and most general com- 

 ments upon the paper. As a whole, the paper is to be com- 

 mended, though I am inclined to think that the author has 

 erred in some instances, which I may here point out briefly, 

 reserving a more extended commentary upon the paper for a 

 more propitious time. 



On page 229 of the cited work, the author describes, under 

 the name of Thryptodus, a large part of the skull of a fish which 

 I am confident belongs to the genus Anqgrnius, as herein de- 

 scribed. The Kansas Museum -pecimen shows the top of the 

 skull well preserved with the exception of the ethmoid and
