THE VOYAGE OF H.M.S. CHALLENGER 
“ The great mass of the specimens collected belong to the suborder Gorgonacea, 
the mere enumeration of the names of which would be without interest. Several species 
of the genus Primnoa were dredged in great quantities. A fine specimen of the

rare Calytrophora japonica, in nearly perfect condition, was dredged from a depth of 
610 fathoms off the Fiji Islands, while another and smaller species of more rigid growth, 
and with the verticels of polyps reversed on 
the stem (Calytrophora wyvillii, n. sp.), was 
taken off the Kermadec Islands from a 
depth of 600 fathoms. There are numerous 
species of Primnoella. In a new species 
(Primnoella murrayi ) from Station 320. at 
a depth of 600 fathoms, the verticels of 
polyps resemble minute cycad cones, from 
the peculiar imbrication of the large external 
scale-like spicules. 
“ The 
narian collected, which shows certain affinities 
to the Primnoads, is the one whose general 
appearance will be best understood from the 
accompanying illustration (fig. 234). It 
was dredged at Station 153, in the Southern 
Ocean, from a depth of 1675 fathoms. The 
stem or main axis is fiexible and only partially calcareous ; around about five-sixths of its 
surface the large polyps are tightly packed, while the remaining one-sixth is free from 
most remarkable form of Alcyo-
