H.M.S. “Lightning,” 1868. Station 12. Lat. 59° 36' N., 
long. 7° 20' W. 530 fathoms. Temp. 47°’3F. Globigerina ooze. 
Three small specimens without arms. 
Station 16. Lat. 61° 2' hi ; long. 12° 4' W. 650 fathoms 
Globigerina ooze. Two small specimens without arms. 
“ Once or twice we found a fragment of the stem of Rhizocrinus 
in the cold area.” * 
Remarks. — So far as my information goes, this widely distributed 
species was never dredged by the “ Porcupine,” not even on the 
the “ LToZi^ewm-ground ” in 1869. But according to Sir Wyville,t 
“ several occurred attached to the beards of the Holteiiioe off the 
Butt of the Lews.” This would be at Stations 47 and 90, both of 
them close to hsTo. xii. of the “Lightning” cruise, which was the 
original LToZ^e^m-ground, and was described by Sir Wyville as being 
in the Faeroe channel. There is, however, no mention of Rhizo- 
crinus in the accounts of the dredgings at these stations, either in 
The Depths of the Sea, or in the Koyal Society Keport ; and I 
suspect therefore that Sir WyviUe was speaking from memory only, 
and confounded the dredgings of the two years. At any rate, if the 
“ Porcupine ” did obtain specimens on the HoUenia-gco\mdi in 1869, 
they have since disappeared. 
Sir Wyville mentioned individuals of considerable size as having 
been dredged by the “ Porcupine ” in 862 fathoms off Cape Clear. 
They really belong, however, to the species which three years later 
was met with off Barbadoes by the “ Hassler,” and was subsequently 
described by Mr Pourtales under the following name : —
