named authors is somewhat uncertain. Stephenson retains Con- 
dylactis “for forms with smooth collar aud no acrorhagi or appreci- 
able sphincter,“ and Parantheopsis “for such as have vertical rows 
of verrucae and also acrorhagi but little or no sphincter." Con- 
cerning the acrorhagi (marginal sphaerules) there are in faet no 
such neither in Condylactis nor in Parantheopsis. True enough 
that McMurrich speaks of pseudoacrorhagi in P. ocellata, and 
Clubb of such in P. eruentata, but at the same time Clubb 
remarks that they have no trace of nematocysts, and McMurrich 
says, concerning the distal papillae in eruentata and the pseudo¬ 
acrorhagi in ocellata, that they have no special development of ne¬ 
matocysts. Under such circumstances these formations cannot be 
considered as pseudoacrorhagi, a name proposed by myself (1899, 
p. 70) for such formations which look like marginal sphaerules 
but are provided with rather numerous nematocysts, though not so 
numerous as in the real acrorhagi (marginal sphaerules). The 
nematocysts of the pseudoacrorhagi are besides of about the same 
length as those of the other part of the column, while the nemato¬ 
cysts of the real acrorhagi mostly are considerably larger. In faet, 
as far I can see, the distal papillae (“pseudoacrorhagi“) are nothing 
but the uppermost verrucae, which are sometimes not so mueh 
contracted as the other verrucae, but more vesicle-like.
