B) Umbellatae: anthocodiaeé distributed terminally. Spicules of anthocodia are mostly rods and spindles, which 
in places pass into clubs. 
a) Exclusively terminal ramification. 
1) Armature weak, the lower part of anthocodia usually without spicules, at least as its ventral, inward 
turned side. CEN rosea (Kor. and DAN:) (Fig. 13 d). 
2) Armature powerful, even in the lower part of anthocodia. E. florida (RATKHE), 1806. 
b) The ramification basal. BP. spitebergensis (DAN.) (Fig. 13 e). 
KÖUKENTHAL distinguishes Hunephthya nephthyiformis as two groups, 1) Divari- 
catae-glomeratae, 2) Umbellatae. "This classification is based upon the different situation 
of the polyps on the branches. To the former group he reckons Hunephthya glomerata 
VERRILL, £. hyalina (DANIELSEN), and £. racemosa (STUDER): and to the latter HH. rosea 
(KOR. and DAN.), H. spitzbergensis (DANIELSEN), and EE. florida (RATHKE). ÅA new

species, H. groenlandica, proposed by myself, belongs to divaricatae-qglomeratae. H. glo- 
merata ineludes two different types. 
The first type has short anthocodiae, at most 3 mm. in length, which are situated in 
large numbers close together on the branches. These latter lie very close to each other. 
The spicules of anthocodiae are short and broad, the ridges on the anthocodiae low. The 
spicules are not so strongly concentrated on the ridges, but lie more evenly distributed 
above the whole anthocodia. The difference between spindles and clubs is not so apparent, 
and the spicules are very broad in relation to their length. (Fig. 13 a.) 
The second type has longer anthocodiae, up to 6 mm., with evident ridges. The an- 
thocodiae well differentiated in shaft and head. The anthocodiae are not placed so close 
together on the branches as in the other type. The spicules in the anthocodiae are longer 
and narrower; the thorns here are more scattered and are higher, but not so broad as in 
the first type. The difference between spindles and clubs very evident, the latter mainly 
on the ridges. (Fig. 13 b.)
