The above-described specimens agree well with A. H. Claek's 

 descriptions of G. parviflora. By my specimens the cirrals are a little 

 shorter; one may, however, also find cirri with longer segments, as 

 my figure of a cirrus from Sp. 4 shows. 



None of these 7 specimens has a genital gland on Pg, contrary 

 to the type specimen from the Siboga St. 50. From some other Siboga- 

 localities, however, there are specimens with a gonad first on P3, as in 

 the Bockian specimens. Might this difference perhaps have the value 

 of variety? The disparity is probably not a difference of age, since 

 for instance Sp. 2 is completely mature and nevertheless has no trace 

 of a genital gland on P^.
