306 SUPPLEMENTARY NOTES 



fest in the passage of one nucleus through the combined protoplasm 

 of the zygote to join the other, which remains in place. 



It is obvious that Ceratiomyxa must be regarded, not as primitive, 

 but as a highly specialized genus, the relationships of which with the 

 Myxogastres, while apparent, cannot at present be more particularly 

 indicated. 



In the discussion of Diachea cerifera G. List. (p. 150) it is noted that 

 this species does not seem to belong in the genus to which it is assigned, 

 and it is suggested that it might better be placed in Leptoderma. 

 Meylan (Bull. Soc. Vaud. Sci. Nat. 58: 82, 1933) transfers the species 

 to Diacheopsis as D. cerifera (G. List.) Meyl. This may prove to be 

 an acceptable solution of the problem of its disposition.
