t This species is probably one of those mentioned in the List of Crinoids 

 of Tennessee, it having been procured from the same district whence Prof. 

 Troost obtained his fine collection of Eucalyptocrini. 



\ Since this part of the Catalogue was in type, I have received through 

 the kind attention of Mr. Meek a paper, entitled " Remarks on the Genus 

 Taxocrinus, (Phillips,) McCoy, 1844, and its relations to Forbesiocrinus, 

 Koninck & Le Hon, 1854, with Descriptions of New Species by F. B. Meek 

 and A. H. Worthen." This paper contains a tabular list of 22 species of 

 American and European Crinoids referred to Forbesiocrinus or Taxiocri- 

 nus, with a statement of the number of radials, interradials, anals, &c, in 

 each, from which it appears very clearly that there are no constant 

 characters by which we can separate Forbesiocrinus as a distinct Genus 

 from Taxocrinus. These authors, however, for the present retain Forbesi- 

 ocrinus in a subgeneric sense, grouping under this name species which 

 possess more than two interradials and anals, and under Taxocrinus not 

 only those which are deficient in these pieces, but those also in which one 

 or two exist. Believing with these authors that it will be convenient to 

 employ both names, at least provisionally, 1 shall here nevertheless follow 

 De Koninck, Le Hon, Pictet, and others, and group in Taxocrinus only 

 such species as are devoid of interradials and anals, and in Forbesiocrinus 

 those having one or more of these pieces.
