560 THE AMERICAN NATURALIST. 
The following descriptive characters may serve to show in 
how far they fail to conform to the type characters of the 
genus: bell ovoid in profile, cuboid as seen from either pole; 
size from 2 to 3 mm. in short diameter by 4 to 5 mm. in 
height. Color a dull amber, somewhat translucent; exum- 
brellar surface dotted irregularly with light brownish warty 
clusters of nematocysts. Tentacles brown in color, rather 
short and spindle-shaped, with deep annulations. Rhopalia 
four, radially located, set in rather deep pockets somewhat 
above the level of the margin, each with several ocelli near 
the tip. Velarium well developed, and strengthened by four 
frenulz or thickenings of the subumbrella in the region of the 
‘radii. - Absence of any traces of velar canals is noteworthy, as 
is likewise absence of mesenterial filaments. Distinct gonads 
could not be distinguished, though sections showed a genital 
region and ova in process of development. Manubrium well 
developed, quadrate in form. In case the specimens may be 
referred to the genus Charibdea, it must be upon the assump- 
tion of immaturity, as Mayer has suggested, in which case they 
compare fairly well with Mayer’s C. aurifera, though in size 
somewhat larger and more brownish in color. If, as seems not 
unlikely, they must be given specific distinctness, I would pro- 
pose for the species the name verrucosa, as significant of the 
warty knots of nematocysts which adorn the outer bell.
