NOTE ON PYROSOMA. DAT 
of Pyrosoma, but they must not be mistaken for such an 
alteration in the relation of the axes of endostyle and stig- 
mata to one another as that which has clearly occurred in 
certain species of Doliolum and in Anchinia. 
I am not aware that Professor Salensky has anywhere 
referred to the inaccuracy I have mentioned above, but 
if the present attempt to point it out should not be per- 
fectly satisfactory to him, I trust that he will refer to the 
subject, and that he will himself do morphologists the 
service of making it clear. For myself I have no hesitation 
in saying that, while fig. 1 is correct, figs. 2 and 3 are 
fundamentally wrong; and that Salensky’s language 
requires correction wherever (¢.g. p. 32) 1t implies that 
the long axes of the stigmata of the Ascidiozooid are 
parallel to the long axis of the endostyle, either in adult 
or embryo.
