﻿WOOD] new and old middle devonic crinoids 77 



the specimens studied agree with Miller and Gurley's figure of thai 

 species in the Illinois State Museum Nat. Hist, Bulletin 4, pi: n, 

 figs. 7, 8, 9. This figure differs widely from that of D. glyptus 

 referred to above. It appears, therefore, that D. ornatus Aleck 

 should stand as a valid species. 



Formation and locality. — Onondaga: Columbus, ( >. A few plates 

 from the Hamilton, at Beargrass creek, Ky., have a similar surface 

 ornament and are referred with doubt to this species.

DOLATOCRINUS CJELATUS Miller and Gurley (?) 

 1896. Miller and Gurley, Til. State Museum Xat. Hist., Bull. 8, p. 41 >, 

 pi. in, figs. 13. 14, 15. 

 A small nodose individual is referred to this species with doubt 

 since the upper part of the calyx is not sufficiently preserved to show 

 the number of arms. 



Formation ant! locality. — Onondaga : Dublin, ( ). Reported from 

 Charlestown and Speed's quarry, Clark county, Ind. 

 Cat. No. 42,434 (Ulrich collection) U. S. N. M. 



DOLATOCRINUS INDIANENSIS Miller and Gurley (?) 



1896. Miller and Gurley, 111. State Museum Nat. Hist., Bull. 8, p. 40, pi. 

 in, figs. 1, 2, 3. 



Two imperfect individuals are referred with doubt to this species. 

 Formation and locality. — Louisville, Ky. The type locality is 

 Hamilton, near Charlestown, Ind.

DOLATOCRINUS WACHSMUTHI n. nom. 



1897. Dolatocrinus lyoni Wachsmuth and Springer (name preoccupied 

 by Miller and Gurley). North Amer. Crinoidea Camerata, p. 314, 

 pi. xxv, figs. 6a, b, c, d. 



A specimen in the collection of the Massachusetts Institute of 

 Technology has been referred to Dolatocrinus lyoni Wachsmuth 

 and Springer, but the specific name lyoni was given by Miller and 

 Gurley in 1896 1 to a widely different species. As the " North Amer- 

 ican Crinoidea Camerata " did not appear until 1897, Miller and 

 Gurley's name has priority. It is here proposed to name the present 

 species for one of its distinguished describers. 



This species is closely related to D. ampins Miller and Gurley, 

 but the latter has four arms in each ray instead of three to the ray
