Not S. indivisa, Stechow, Abh. math.-phys. Klasse K. 

 Bayer Akad. Wissensch., iii. Suppl.-Bd., 1913, p. 134, 

 figs. 106, 107 ; (Sertularella No. 9, Inaba, Zool. Mag. 

 Tokyo, 1890, figs. 22-25). 



Hartlaub has united 8. indivisa, S. solidula, and S. varia- 

 bilis under the name of S. solidula, and in view of the extreme 

 range of variation found among these forms, I cannot but 

 concur in his judgment. The species, however, must be 

 named S. indivisa instead of 8. solidula^ the former name 

 having priority. 



Hartlaub also considers it probable that the S. sieboldi and 

 S. muelleri of Kirchenpauer belong to the same species. It 

 would be impossible to identify them from Kirchenpauer's 

 -account, but Hartlaub's descriptions and figures seem to 

 me to support his opinion. 



S. exigua, Thompson, is also ranked by Hartlaub as a 

 synonym, on the strength of specimens marked S. exigua in 

 the Kirchenpauer collection. 8. exigua, however, has four- 

 toothed hydrothecse, consequently Kirchenpauer's specimen 

 must be incorrectly referred to that species. 



Inaba's Species 9, which Stechow refers to S. indivisa, is 

 also a four-toothed form, and, therefore, its reference to 

 S. indivisa is inadmissible. 



The " Endeavour " specimens agree pretty closely with the 

 typical S. indivisa, but are very thin and delicate. Most of 

 them were growing on S. adpressa, Ritchie.
