[BIGELOW] A NEW GENUS OF ANTHOMEDUSÆ 95 
from the Pandeide, the presence of labial knobs, is certainly of far less 
phylogenetic importance than the structure of the tentacles, because 
in Calycopsis (an offshoot no doubt, of the Pandeidæ) one species 
has them, others lack them (1913, Hartlaub, 1913). 
The abaxial ocelli, too, further suggest a Pandeid relationship, 
for as a rule the ocelli of Cytæidæ and Bougainvilleide are axial, if 
present, though this is not invariably the case (Maas, 1909, has des- 
cribed them as abaxial in his Turritopsis Pactfica').
