1) In the figure (PL XXIII, fig. 73) the median antenna is ahsent, presumahly because 

 Kinberg confounded the frontal tubercle with it; as well-known, he overlooked also the ventral jaw. 



2) On account of the absence of a notopodium in the parapodia Ehlers based a new genus 

 Leocratidcs on this species. However it jjossesses a small acicula in the base of its dorsal cirrus 

 and the anterior parapodia in the species of Leocrates also lack the notopodium; therefore I 

 believe that the species can be ranged in the genus Leocruies. 



3) By Ehlers considered as identical with Leocr. chinensis Kbg. (Die Polychaeten des Ma- 

 gellan, und Chilen. strandes, 1901, p. 83, PI. XI, figs. 10—15). 



4) According to the explanations of Von Marenzeller (Zur Kenntniss der Adriat. Anneli- 

 den, I, p. 130) and of Marion et Bobretzky (loc. cit.) the name Oxydromus can no longer be 

 maintained. • ■
