Remarks on the genus TAXOCRINTJS, (Phillips) McCoy, 1844; and its relations 

 to FORBESIOCRINUS, Koninck and Le Hon, 1854, with descriptions of new 

 species. 



BY F. B. MEEK AND A. H. WORTHEN. 



The genus Taxocrinus, Phillips, as published by McCoy in 1844, (Carb. Foss. 

 Ireland, p. 178,) was founded upon Cyathocrinus ? macrodaclylus, Phillips, and 

 Taxocrinus polydactylus, McCoy, both of which are described, and the latter 

 figured by McCoy, as if- composed of five basal pieces directly alternating 

 with the five radial series, the latter forming free arms without any interra- 

 dial or anal pieces between. Phillips' figures of T. macrodactylus, however, 

 (Palaeozoic Fossils, pi. xv.,) particularly his figure b, certainly shows a small 

 interradial piece wedged in between the truncated superior lateral angles of two 

 of the first radial pieces. From these illustrations, therefore, as well as from 

 the fact that in redescribing the genus in 1851, according to the later im- 

 proved nomenclature of the parts, (Brit. Pal. Foss. p. 51,) McCoy distinctly 

 says " five hexagonal interradial plates intervene between the second primary 

 radials, resting on the upper lateral edges of the 1st do.,"* it is manifest 

 that there is generally, if not always, one or two ranges of interradial pieces, 

 in adult examples of what are regarded in Europe as typical species of this 

 genus, when found entire. 



* From the species included, as well as from that author's usual method of describing these 

 parts of crinuids, it is obvious that by,the words " five hexagonal interradial plates intervening, 

 Ac," he means a single piece occupies each of the five interradial, or rather four interradial, 

 and one anal spaces.
