" The following remarks are intended to bring the above 

 Report up to the present date, so far as the writer (who 

 has been absent from the district for several years) is able. 



p. 233. Polynoe extenuata, here mentioned, should be 

 referred to P. reticulata, Claparede. 



p. 234. Polynoe prop in qua, Mgrn. is the Lepidonotus 

 semisculptus of Johnston's Brit. Museum Catalogue, and 

 hence should appear now as Polynoe semisculpta. 



p. 235. Undoubtedly the P. floccosa of Prof. M'Intosh's 

 list is also a synonym for the last named species, P. 

 semisculpta. 



p. 255. Joyeux Lafuie (Archiv. d. Zool. Exp. (Ser. 2), 

 viii., p. 244, 1890) shows that only one European species 

 of Ghcetopterus exists, viz., C. variopedatus, Ren., hence 

 this name replaces that of C. insignis. 



p. 256. The form here entered as Siphonostoma dip- 

 lochaUos has been shown by further investigation to be 

 the Flabelligera affinis of Malmgren. 



p. 248. Here is given a note on the embryology of 

 Arenicola and of Scoloplos, and while the remarks relating 

 to the latter have been found to require no correction, 

 my experience on the Jersey Coast has brought up facts 

 which show that an error was made as to the parent 

 species of those larvae described as belonging to Arenicola', 

 hence this note must be corrected by the substitution of 

 the name Phyllodoce macula ta for that of Arenicola. 

 With this alteration of name the description holds good. 

 In the description of pi. xiv., figs. 12 to 21 refer therefore 

 to the embryology of Phyllodoce macula ta, and not to 

 Arenicola. " 



Since Mr. Hornell left Liverpool for Jersey three 

 additional species of Polyclneta have been added, viz., 

 Arenicola ecaudata, Johnston, Magelona papillicornis, 

 Mull., and Autolytus longisetosus, Orst.
