In my paper. On Hermaphroditism in viviparous Op/iiurids, I have stated (p. 10) that 

 this species appears to be a protandric hermaphrodite, the old and poorly preserved 

 material then at my disposal making this statement, however, somewhat uncertain. On a 

 renewed examination of the rich material now at hand I find that it is not protandric. 



Specimens of 5-6 mm. diameter already show gonads of distinctly female character. 

 I think that in one case I have discerned a male gonad in a specimen of 6 mm. diameter 

 of disk, together with distinct female gonads. But otherwise I have found only female 

 gonads in all the numerous specimens of various sizes, from 5 to 18 mm. diameter of disk. 

 (Among the specimens of var. pentactis male specimens are quite common.) This is 

 quite a perplexing case ; one is, indeed, tempted to suggest that the species is usually 

 parthenogenetic. I have re-examined some preparations on which the statements in my 

 paper of 1920 about the hermaphroditism of this species are (partly) based, and find that 

 there is, at least, one clearly hermaphrodite gonad from a specimen of 9-5 mm. dia-
