This speeies was first described by Haeckel from specimens 

 in alcohol belonging to the Museum at Copenhagen, and tåken off 

 the AVest coast of Greenland. In 1898, Grønberg again described 

 and figured the speeies with the advantage of having seen living 

 specimens at Spitzbergen in 1896. The solitary specimen in this 

 collection agrees with Grønberga description, which amends that 

 given by Haeckel. 



Haeckel instituted a new genus, Codonium, for those Sarsiadae 

 which have a cone-shaped process on the top of the umbrella; 

 the sole character which distinguishes them from the genus Sarsia. 

 Certainly some of the speeies placed in the genus Codonium are 

 true Sarsia even according to Haeckel's definition of the genus, 

 forinstance, Codonium gemmiferam (Forbes) and Codonium pulehellum 

 (Forbes). Codonium princeps should be included in the genus 

 Sarsia, as the umbrella has not a true, well-defined, apical process 

 on its top. I doubt very much if this minute distinction is worthy 

 to be a generic character, and would not be belter employed as a 

 speciiic character. It separates into different genera two speeies, 

 Codonium eodonophorum and Sarsia prolifera, which should be in 

 the same genus, namely, Sarsia.
