88 " ENDEAVOUR " SCIEMTIFIC RESULTS. 



Family GORGONELLID.^. 



Genus Ctenocella, Valenciennes. 



Simpson^ and Xutting- have both shown that the genus 

 Scirpearia, as inulerstood by authors generally, is not iden- 

 tical Avith that of Cuvier, the latter being based on a Pen- 

 natulid. Simpson has retained the genus in its emended 

 form, which, however, cannot be admitted according to the 

 rules of zoological nomenclature. Xutting, on the other 

 hand, has distributed the various species AAhich were in- 

 cluded in Scirpearia into other genera of the Gorgonellidaj. 



Simpson also argued that Ctenocella is not distinct from 

 his emended Scirpearia from Avhich it only differs in the 

 mode of branching. If his opinion be accepted, the single 

 sjiecies of Ctenocella [C. pectinata) must be placed in one of 

 the several genera into A\hich Nutting has distributed the 

 various species erroniously included in Scirpearia. Nutting, 

 however, has not recognised the identity of Ctenocella and 

 Scirpearia (emended), but maintains it as a good genus ; 

 under the circumstances I prefer to follow him.
