I have designated this species by the name of H. elongata instead of H. cordifera, 

 under which it is usually known, especially since the publication of Lyman's work, 

 first because the name elongata had been applied to it by Say in 1825, and again 

 because the term "cordifera" has produced some confusion, which I think is due 

 chiefly to Lyman and has never yet been pointed out. In fact, Lyman, who, in 

 1865, gave an excellent description of the species with which we are dealing, thought 

 that it was the same as had been called by Bosc, in 1 830, Asterias cordifera. Now, the 

 latter is an Amphiura of the Amphiodia section, in which the under face of the disk 

 is provided with scales; Liitken gave that synonymy in 1859, when he published 

 a good description and some figures of the said Amphiodia which he called AmpJiiura 

 cordifera (Bosc) in his "Additamenta " (59, p. 115); also in I860, 1 when he called it 

 AmpJiiura riisei. In 1859, in the same volume of the "Additamenta," he pub- 

 lished also a good description and some drawings of Amphiura elongata, (Say). 

 The two species described by Liitken were perfectly distinct, and the descriptions, 

 as well as the figures published by him, were excellent. There would have been, con- 

 sequently, no difficulty due to synonymy concerning Hemipholis elongata had not 

 Lyman, in 1865, adopting the generic name of HemipJiolis suggested by Agassiz, 

 described AmpJiiura elongata under the name of H. cordifera, thus considering this 

 form to be synonymous with Asterias cordifera Bosc. Later, in 1882, he published 

 in the Reports of the ChaUenger (82, p. 158) a synonymic list for his Hemipholis 

 cordifera which contained the same errors. One can hardly account for Lyman's 

 considering as synonymous two forms so clearly distinct as those which Liitken 

 had so well described and figured under the names of Amphiura elongata and A. 

 cordifera. 



Consequently, for the Hemipholis distinguished by Say in 1825 the name of 

 elongata, which he had applied to it, must be kept.
