ophiurians matching it so exactly in color. It probably belongs 
to the genus Gorgonella. The colony is flabellate in form with 
the branches occasionally anastomosing, and some specimens at- 
tain a height of about eighteen inches. It was the commonest 
gorgonian found in our dredging, being secured at various sta- 
tions. It is also the most beautiful aleyonarian secured by us, 
being a brilliant coral red with light yellow calyces that appear 
almost white against the red background. The ecalyces are 
usually biserially arranged, alternating along the antero-lateral 
edges of the branches, their walls being formed largely of rows 
of perpendicular spicules which also encrust the dorsal sur- 
faces of the infolded tentacles. The cortex spicules of the stem 
and branches are bright red and in the form of girdled spindles 
characteristic of the family Gorgonellide. The axis cylinder is 
ivory white, smooth and calcareous throughout. 
Three other species belonging to this same family are allied 
to the genus Juncella. They are unbranched rod-like colonies, 
showing a longitudinal band devoid of polyps. The first of 
these was from Station 55, depth 33 fathoms. The ecalyces are 
elub-shaped, facing upward with their sides pressed to the 
stem and their walls armed with a mosaic of red spicules which 
also encrust the dorsal surface of the infolded tentacles. ‘The 
spicules are the double clubs and double stars characteristic of 
the genus. Another species from Station 78, depth 35 to 75 
fathoms, had much larger calyces, but was also deep red in 
color; and still another from the same station had very prom- 
inent calyces which were cylindrical in shape and very much 
more prominent than in any of the other species. 
A very fine primnoid was dredged at Station 46, depth 100 
fathoms. Two large flabellate specimens came up, appearing 
to be parts of the same colony. If so, the whole colony would 
be about seventeen inches high. It belongs to the genus Primnoa 
in the original sense, but would now most likely find a place 
in the genus Caligorgia. The calyces are in the form of bent 
elubs facing upward and inward and with walls beset with reg- 
ular rows of scale-like ctenate spicules in imbricating series. 
The polyps are in whorls of four and the specimen bears a gen- 
eral resemblance to Primnoa pourtalesi. 
Among the shallow-water forms of gorgonians, by far the
