XXIII. On a Specimen of Osfeocella se[^teiitiionalis (Gray). 

 By Sydney J. Hickson, F.R.S. 



Professor of Zoology in ilic University of Mauchesler. 

 Received and read May gth, igi i. 



In January of this year Professor Bell asked me to 

 examine " some pieces of Osteocella with the polyps on," 

 that had been sent to him by Rev. J. H. Keen. My 

 memory being at fault, I referred to the literature of 

 P ennatulida and found that Gray's genus Osteocella 

 founded on some specimens of the axes of Peuftaiulids 

 had almost been forgotten, the specimens, when referred 

 to, being assigned without much reason by different 

 authors to other and better known genera. 



The " pieces,'' unfortunately, do not make up the 

 whole of this magnificent specimen, but represent 

 different regions cut out in lengths of from lOO — 200 mm. 



Fortunately, however, the pieces are very well pre- 

 served, and it is possible to study nearly all the important 

 features that the species exhibits. 



The following particulars were supplied by Rev. J. H. 

 Keen : — The specimen was taken off Lucy Island, seven 

 miles S.W. of Metlakatla, British Columbia, in about 

 30 fathoms, December 15th, 1910. 



" It came up on a halibut hook with a dogfish. The 

 dogfish, on finding itself hooked, had rushed round and 

 round the pennatulid, which was completely tied up in the 

 line. It was alive when procured and writhed like a worm.
