Obs. — Pfeffer originally suggested that this species was a 

 young form of Cavolinia trispinosa, but Boas objected to this 

 view. Pelseneer agrees with Pfelfer and enters fully into his 

 reasons for so doing in Challenger Zoology, vol. xxiii., p. 87. 

 For further information for those interested I therefore append 

 a copy of the synonymy of Cavolinia trispinosa, Lesueur.
