88 " EXDEAVOUK " SCIENTIFIC RESULTS. 



Family GORGOXELLID.E. 



Genus Ctenocella. Valenciennes. 



Simpson^ and Xutting- have both shown that the genus 

 Scirpearia, as understood b}^ authors generally, is not iden- 

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

 ziatulid. 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 which were in- 

 cluded in Scirpearia into other genera of the Gorgonellidse. 



Simpson also argued that Ctenocelki is not distinct from 

 his emended Scirpearia. from which it only differs in the 

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

 species of Ctenocella {C. jjectinata) must be placed in one of 

 the several genera into which Xutting has distributed the 

 various species erroniously included in Scirpearia. Xutting, 

 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.
