the great development of the spicules between the coelenterons, which prevents a deve- 
lopment of the indirect canals. Lower down in the trunk, the endodermal indirect ca- 
nal system reaches a better development, the formation of the spicules being weaker. In 
the branches and in the trunks as well, the space between the coelenterons is rather in- 
significant, the branches are smaller and the coelenterons numerous and this, of course, 
as the distribution of the coelenterons does not occur in profuse ramification, may lead 
to direct connection, a feature we have already observed in other cases, as for instance, 
in the Hunephthya flavescens (= E. racemosa STUDER). 
Habitat: 
Greenland, east coast, without definite locality 234 met., clay with stones (Sofia 
exp., '/; 1883), 5 sps. 
Eunephthya rosea (KOR. and DAN.), 1883. 
Diagnosis: The ramification is umbellate and terminal, and as a result there 
is formed a cushion-like collection of anthocodiae. Spicules in anthocodiae are rods, 
spindles, and a few clubs and crosses. The lower part of anthocodiae is without spicules, 
at least on its ventral, inner side. No evident ridges on the anthocodiae. The anthoco-

In 1879 VERRILL described Alcyonium multiflorum from the waters of Newfoundland. 
KOREN and DANIELSEN, in 1883, note that this species seems to approximate to their species 
Duva rosea. WVERRILL points out the hypothetical relationship with Gorgonia florida, 
RATHEE. That the species not is to be referred to the genus Alcyomium is evident. It 
surely belongs to the genus Hunephthya (sensu MOLANDER). The brief account of VERRILL 
is not sufficient to allow us to judge whether this species may be considered as E. rosea 
(KOREN and DANIELSEN) or as É. florida (RATHKE). The geographical distribution of 
E. rosea includes other American waters, and it is very likely that Alcyonium maultiflorum 
is identical with £. rosea. On account of the rules of nomenclature the Z. rosea (KOR. 
and DAN.) should be replaced by £. multiflora (VERRILL), but I retain the name E. rosea, 
as VERRILL'S description does not provide any certain grounds for defining the real 
nature of Alcyonmium multiflorum as E. rosea or KH. tlorida. 
BrocH (1912) classes Funephthya rosea, E. florida, and E. spitzbergensis together as 
one species, Z. florida (RATHKE). BRocH has evidently made a mistake in this. The terminal 
ramification with £. rosea and £. florida distinguish them very clearly from ZE. spitzber- 
gensis. The differences between the armature are less. The spicules of the anthocodiae of 
E. florida and E. rosea are mostly rods and spindles, within £. spitzbergensis these spicules 
are mixed with numerous clubs, and they also have greater length. The distinction 
between HX. rosea and ZE. florida is connected with the stronger development of spicules
