I, — Additional Notes on the Nexo Fossil,, Daimonelix. Its 

 Mode of Occurrence,, its Gross and Minute Structure. 



By ERWIN HINCKLEY BARBOUR. 



In deference to the ranchmen and early settlers of north- 

 western Nebraska, the name Daimonelix has been applied by 

 the author to certain gigantic fossils known to them as the 

 'Devil's Corkscrews' or 'fossil twisters.' 



At first sight, the name seems perhaps to savor somewhat of 

 the wild west, yet a moment's reflection will sufiice to remind 

 any naturalist that one finds a justification for this early name 

 in the 'devil's fingers,' 'devil fish,' 'Devil's Tower,' and the 

 like, so familiar to all. 



These great twisters were examined by the author for the 

 first time in June of 1891, when one specimen was secured, 

 though many others were observed, measured and sketched; 

 and, as sufficient data had been obtained, a brief illustrated 

 description was published in Science^ February 19, 1892, in 

 which the name Daimonelix was proposed for 'Devil's Cork- 

 screws. ' These new fossil beds were visited a second time by 

 the author in May, 1892. At that time, within ten days, in 

 spite of the storms and unseasonable blizzards which prevailed, 

 many localities were visited and a large number of excellent 

 specimens secured. The material then obtained furnished 

 facts for a second paper which was published in the University 

 Studies,, July, 1892, under the title On a Nero Order of Gi- 



Univkrsity Studies, Vol. II, No. 1, July, 189-4.
