Gersemia uvaeformis (MAY), 1900. 
Diagnosis: "The anthocodiae are numerous on each branch. The lower part of the 
anthocodia without spicules. The spicules of the upper part of the anthocodia are spindles 
and rods with strong thorns. Spicules of branch bark (basal spicules) are numerous 
and consist partly of rollers with girdles (dumb-bells not so conspicuous), partly of 
larger spindles and clubs; 0.1—0.3 mm. (Pl. I, fig. 1.) 
1907, Eunephthya uvaeformis, KÖKENTHAL. 
This species very much resembles the Gersemia rubiformis, but differs in many 
respects, however. The colony does not attain the size of G. rubiformis, and it lacks its 
profuse ramification. The trunk is visible, in the case of better developed specimens 
at least. The branches are expanded at the points and bear anthocodiae. These, whose 
length varies between 1 and 3 mm., depending on age and degree of contraction, are closely 
packed and have a clear calyx. This is pointed out by KUKENTHAL as something specific 
for this species, but as we have already noticed in the previous species, it is of rather 
usual occurrence. That it appears here as a rule is explained by the powerful armature 
in the branch bark and by the considerable size of these spicules, and also by the fact that 
the anthocodiae lie very close. In the upper part of the anthocodia are situated large, broad 
spindles, arranged in numerous rows and usually with strong thorns, which are very uni- 
formly distributed. These spindles are very typical and are easy to distinguish from 
those of Gersemia rubiformis, which, as regards position, correspond to them. The lower 
part of the anthocodia is without spicules. In the branch bark there are to be found, 
intermingled, lärge spindle- and club-shaped spicules and small rollers with girdles. 
The trunk spicules are narrower, are spindle-shaped, and have long, narrow thorns. 
The coenenchym between the coelenterons is, in most cases, without spicules.
