In 1890, Dr. Clemens Schluter, of Bonn, suggested to the writer that 

 the specimen figured on Plate 11 of this volume is clearly a species of 

 Podocrates, closely allied to if not identical with P. Dulmenensis, as 

 stated in the Transactions of the Royal Society of Canada for 1895. 



Still more recently, on receipt of the American Journal of Science for 

 October, 1897, containing a description, with illustrations, of Linujyarus 

 atavus, the writer was struck with the resemblance of the specimens 

 figured under that name to Podocrates Canadensis. In a correspondence 

 which ensued, Dr. Ortmann says that he is now fully convinced of the 

 identity of Linuparus atavus with Podocrates Canadensis, and that the 

 species should be referfed to the genus Linuparus, which was proposed by 

 Gray, in 1847,* and based upon the recent Palinurus trigonus of De 

 Haan. He also says that the genus Podocrates was first published by 

 Geinitz in 1850, and that it is founded on a good figure.
