Stomotoca apicata (McCrady). Fig. 77. 
( Saphenia apicata McCr. Proc. Elliott Soc., vol. I, No. 1, p. 130.) 
Male . — Bell broad and shallow, with a long conical projection at its summit. Marginal tentacles 2, 
very long, but capable of retracting into short, finger-like bodies as in the figure; rudiments of other 
tentacles around the margin. Proboscis very large and bulky, composed of lobes that extend to the 4 
mouth tentacles, which are pointed and reach below the velum. Radial canals 4. 
Colors . — Tentacles rich purple, tipped with olive green. Spermaries and basal part of proboscis 
clear light emerald green. These colors differ greatly from those given by McCrady. They are taken 
by myself from a living specimen. 
Female (==Dinamatella cavosa Fewkes). — Bell subglobular with a cone-shaped apical projection, 
the cone being shorter than in the male, and divided into two portions, a basal dome-shaped portion 
being surmounted by the short subconical apical part. Tentacles 2, hollow, very long ; besides these 
there are 6 rudimentary tentacles on the bell margin which bear pigment spots at their bases. 
Gemmaria cladophora A. Ag. Fig. 78. 
(North American Acalephje, p. 184.) 
Bell rather deep, the apical portion being elevated into a shallow rounded dome not sharply, but 
still evidently differentiated from the rest of the bell. Tentacles 4, two of which are much the longest 
and bear curious clusters of nematocysts borne on short stalks or pedicels. Proboscis scarcely reach-
