GENUS EUCALYPTOCRINUS. 329 



EUCALYPTOCKINUS ORNATUS. 



Eucalyptocrinus ornatus : Hall, Report of Progress Geol. Survey of Wisconsin, 



1861, p. 20. 



This species is common at Racine and Waukesha. It occurs as casts of 

 the interior, but retaining the marks of its structure in a greater or less 

 degree of perfection. The impressions of the exterior in the compact lime- 

 stone are very well marked and characteristic of the species. 



Some specimens of the casts have a somewhat obtusely pentagonal form, 

 with a broad spreading base, and a constricted upper margin. In this con- 

 dition they much resemble in form and proportions the Rhodocrinus me- 

 lissa of the Niagara shale at Waldron, Indiana. 



EUCALYPTOCRINUS C^LATUS. 



Eucalyptocrinus ccelatus : Hall, Pal. of New-York, Vol. ii, pa. 210, pi. 47, f. 4. 



Some specimens of casts of the interior and impressions of the exterior 

 surface of a species of Eucalyptocrinus, from Waukesha, appear to me not 

 to be distinguishable from the New'York species.
