REMARKS BY THE PUBLISHING COMMITTEE. 



In concluding the present volume, the publishing 

 committee consider it a duty which they owe to the 

 readers of the Journal and to themselves, to state, that 

 when the paper of Mr. Rafinesque was admitted into the 

 preceding pages, they were not informed that a portion 

 of it had already appeared in a contemporary jouroial, 

 otherwise, agreeably to the plan upon which the work 

 has been conducted, that paper, or at least the exception- 

 able portion of it, would have been rejected; this proce- 

 dure would have been indispensable for the interest of 

 science, as one of the species described, had been previ- 

 ously published, by Mr. Rafinesque, under a different 

 specific name, and no direct reference is given by which 

 its identity might be detected; it is therefore proper to 



state, that JSxogiossum Lesurianum of this Journal is 

 Vol. I. R r
