History. The single species of this genus was described by Carpenter under the 

 generic name Antedon. In 1907, upon the creation of that genus, it was removed to 

 Heliometra. 



In 1911 the name Solanometra first appeared, with no indication of its intent, but 

 covering, by inference, the species both of Solanometra and of Florometra as now under- 

 stood. It was used in this sense in 1913, when it appeared as a subgenus of Proma- 

 chocrinus, including the single species antarctica, Florometra being also used to include 

 magellanica and by inference the species associated with it. 



In 1914 the type species of Solanometra was given as Antedon antarctica, and in 

 1915 a diagnosis was published; it was still, as in 1913 and in 1914, regarded as a sub- 

 genus of Promachocrinus, but in my Ingolj report of 1923, I used Solanometra as a 

 generic name in a key to the genera of Heliometrinae. Since then other authors have 

 also treated it as a fuh 1 genus.
