Position and locality : The specimen is labeled, "From the Upper 

 Coal Measures ; Kansas City." University of Kansas Museum. 



It is impossible to locate the specimen generically with any degree 

 of certainty without more of the specimen preserved. The ventral 

 sac seems to have been angular and the stem round. For this rea- 

 son it is left with Zeacrimcs. The upper extremities of the radials 

 do not meet, but leave a small aperture, which seems to communicate 

 in life with the general body cavity. I know of no Coal Measures 

 crinoid with which it is likely to be confounded. 



January, 1900.
