Prof. Dewey on Caricography. 171 
The elegant Crinoidean, Cyathocrinus ornatus, figured in 
Hall’s Report, p. 247, has been found in great numbers and in a 
very perfect state of preservation on the shores of Lake Erie ina 
stratum about six inches thick, thinning out in every direction 
within five feet of the centre. r. Carley, of Cincinnati, who 
received a specimen of this fossil, has succeeded, by great perse- 
verance, in developing a most remarkable elongation of the vis- 
ceral receptacle, several inches in length within the tentacule.
