 St/n. Bhodoor. Barrisi var. divergens Hall, 1861. Desc. New Sp. Crin., p. 



9; also Best. Journ. Nat. Hist., p. 324, PI. 6, fig. 18. 

 A comparison witb the type specimen and with others in our cabinet, proves 



beyond doubt that the original B. Barrisi was described from a very young 



specimen, and this explains fully the additional bifurcation in the variety or 



older specimen. 

 1836. Bhodoor. globosus Phillips. (Actinoor. globosus) Geol. Yorkshire, p. 206, 



PI. 4, figs. 26, 29. Mount, limest. Yorkshire, Engl.

22, 23, 25, PI. X, fig. 1. Grauwacke. Niederlabnstein, Germ. 

 This species is only known from casts, and may possibly belong to some other 



allied genus.

Cab. Nat. Hist., p. 127. Hamilton gr. Ontario Co., N. Y.

a, b. Niagara gr. Near Louisville, Ky. 

 This species is certainly not Bhodoorinus, but the type specimen is too imper- 

 fect for accurate diagnosis.

 1860. Bhodocr. Varsoviensis Hall. Supp. Geol. Rep. Iowa, p. 80. Warsaw limest.

II, 12. Upper Coal Measures? 30 mibs west of Humbolt, Kans. 



We doubt if this fossil came from the coal measures, neither Aciinocrinvs nor 

 RhodocrinuH have ever been found to occur la'er than the age of the Warsaw 

 limestone.
