DESCRIPTION OF SPECIES 71 



Michaelsen (1924) found brood pouches in S. sigillinoid.es containing from one to three larvae, and 

 I have found from two to fourteen in different specimens of the same species. I therefore agree with 

 van Name (1945) and Kott (1954) that S. ramulosa is a synonym of S. sigillinoides. 



Regarding S. ambellata (Michaelsen) both Michaelsen (1924) himself and Arnback (1950) are 

 inclined to regard this also as a synonym of S. sigillinoides. 



S. georgiana (Michaelsen) is another form which some authors think might be S. sigillinoides (Brewin, 

 1953). But I believe that the speciess hould be maintained (see p. 74), although I am not altogether 

 sure that it is distinct from S. gaimardi (Herdman), an insufficiently known form. 



Herdman (1886) described S. quoyi from Kerguelen, but his description did not sufficiently dis- 

 tinguish it from S. sigillinoides. Kott (1954) maintains their separation on the grounds of slight 

 anatomical distinctions in the gut and the much larger size of the larva. In view of the variations in 

 larval size which can occur within one species I am still doubtful about the validity of S. quoyi.
