BUDDING IN TUNICATA. 



NOTE. 



Corrigendum. — Upon referring again to Fol's memoir 

 on the Appendiculariidse (a work which I was unable to 

 consult when writing my recent article on Budding in 

 Tunicata), I find that two unessential details in that article 

 require correction. Fol cannot be credited with the theory 

 to which I referred on pp. 51 and 52, in spite of the am- 

 biguity of his remarks on Doliolum (Fol, p. 6, footnote) ; 

 and Kowalevskia, to which I referred on p. 52, seems in 

 reality (Fol, pi. xi., fig. 5) to possess a circlet of fine cilia in 

 its branchial canals, although no statement to this effect is 

 made in the text, and no cilia are represented on pi. xi.,
