promise of satisfactorily solving the nomen- 

 clature problem. 



Professor Joseph F. James made some 

 remarks on ' Daimonelix and Allied Fossil.' 

 He gave an account of the large fossil 

 ' cork screws ' described by Professor Bar- 

 bour from the Bad-Lands of northwestern 

 Nebraska, calling attention to their peculiar 

 features. He noted the fact that while they 

 had heretofore been considered as unique 

 and without resemblance to other fossils, 

 that in reality several other similar forms 

 had been described. One of these was 

 figured by Heer in 1865 in ' Die Urwelt der 

 Schweiz,' under the name of ' screw-stones,' 

 which presents all the characters of Daim- 

 onelix as figured by Barbour. In 1863 Pro- 

 fessor James Hall described Spirophyton and 

 gave a restoration of S. typum. In a view 

 of one of the whorls there is a great corre- 

 spondence between it and a figure of the 

 same character given by Barbour. In 1883 

 Professor Newberry described Spiraxis, also 

 a genus of screw-like fossils which presents 

 features similar to Daimonelix. Heer's fossil 

 occurs in the Miocene of Switzerland, while 

 Spirophyton and Spiraxis occur in the Che- 

 mung of New York and Pennsylvania. The 

 wide distribution of the forms is interesting 

 as showing that Daimonelix is not an ' acci- 

 dent ' as hinted by some. Whether it is a 

 plant or not must be decided in the future, 

 although there is a strong presumption that 

 such is the case. Fbedeeio A. Lucas,
