S. A. Miller, 1883, Journ. Cincin. Soc. Nat. Hist., vol. vi, p. 224.— Hudson 

 gr. Cincinnati, Ohio. 

 Meek's description of this species, upon which the Cincinnati paleontologists 

 have tried to identify it, is based upon specimens which did not show its 

 characters, and therefore cannot be relied upon. Hall's figure exhibit? :i 

 well-marked form, it shows plainly that it must have underbasals, and that 

 a small anal plate extends down to the basals.

*1882. D. waldronensis (Miller and Dyer), Cyathocrinus waldronensis, Journ. 

 Cincin. Soc. Nat. Hist., July (Abstr., p. 6), PI. 4, fig. 9.— Niagara gr. (We 

 have seen in the collection of Mr. Wm. Gurley, of Danville, a specimen 

 which shows plainly the presence of dorsal interradials ; and this feature, 

 together with the double-jointed arm structure, proves, beyond doubt, that 

 it is not a Cyathocrinoid).

Additional species : — 



1879. (?) L. parvus Hall, Trans. Alb. Inst., vol. x (Abstr., p. 9).— Niagara gr. Wal- 

 dron, Ind. (This may be a young specimen of L. tennesseensis. It appar- 

 ently differs only in the much smaller size, and in having but four anal 

 plates).

a. Stelidiocrinites. 



(?) BRIAROCRINTJS Angl., Rev. ii, p. 96. 



This is one of the genera in which we cannot trace satisfactorily 

 the family relations, being in some of the characters allied to the 

 Ichthyocrinidae.
