In connexion with the interesting observations on the 

 "Palolo'^ of Samoa {Eunice viridis, Gray) by Mr. McM. 

 Woodworth in the ' American Naturalist •" for December, 

 1903, a somewhat imperfect digest of which appeared in 

 ' Nature' of March 31st, 1904 f, it is well to remember that 

 previous observers had tilled in much of the gap. Thus, 

 even in the case of the first examples as described by Dr. Gray J, 

 the discoverer, Mr. Stair, stated that the worm came from 

 the coral-reefs. Subsequent observers knew that they dwelt 

 in fissures and crevices of the rocks at and near low water, 

 and that the swarming of the headless portions was connected 

 with reproduction. The first head was described and figured 

 by Dr. J. D. Macdonald§, one of those able naval surgeons, 

 like Huxley and Moss, who have — when on duty on Ijoard 

 ship — largely contributed to our knowledge of marine animals. 

 Eunicids are very abundant in cracks and fissures of rocks 

 everywhere, and especially in coral-reefs; but it has yet to 

 be proved that they bore in the latter. Moreover, epitokous 

 annelids have been familiar to zoologists for a long time, 

 and the step to link on the '' Palolo '' of Samoa therewith 

 was brief, for it was evidently the posterior region distended

t Since this date a long discussion as to priority in finding that " Palolo " 

 was Etmice viridis has taken place between Benedict Friedliinder and 

 Ivi-iimer {cf. Zool. Anzeiger, July 12, 1904).
