Meyer did not state the number of times that the different 
combinations were found, nor did he indicate whether any of 
the numbers or combinations of numbers were met with more 
frequently than others. I am inclined to regard his case A as 
another in which gonidia were mistaken for eggs or oospores 
on account of their great size. Likewise the one and two 
oospores of his NB cases. 
Meyer’s attention at the time when he described this species 
was directed more especially to the subject of intercellular pro- 
toplasmic connections and cell membranes. His new species 
differed from two species of Volvox in which he had made a 
detailed study of those connections and membranes. It en- 
tirely lacked the protoplasmic connections between the proto- 
plasts of the adults, though such connections were said to be 
readily visible between the cells of living, unborn daughter 
coenobia (Meyer, ’96, p. 200, pl. 8, fig. a). It differed from the 
other species also in the form of the membranes of the somatic 
cells. His diagrammatic drawings, based on careful study of 
stained material, are reproduced herewith as text fig. 1. The 
protoplasts are shown globose in form, about 7.5 pw in diameter 
(Meyer, ’96. pl. 8, fig. z), and separated each from its own
