NOTES ON SOME RARE COPEPODA FROM SCOTLAND 239 
other things besides the starfishes mentioned were brought up on 
the hooks, and among others were a few large Annelids, probably 
belonging to a species of Sadella. These Annelids form tubes of 
fine mud, which is mixed with and held together by a glutinous 
substance secreted by the animal. These tubes were found to be 
invariably more or less covered by a growth of Alcyontum. In 
some instances these tubes contained the living Annelid, but several 
of them were empty. It was only when fishing in moderately deep 
water—t15 to 20 fathoms or so—that these large worm-tubes were 
obtained. Though the Alcyonium had usually spread itself over a 
Jarge portion of the tubes, the upper end—the end that corresponded 
with the head of the worm—was generally free from the enveloping 
Zoophyte. White specks were observed on nearly all the specimens, 
and were sparingly scattered over the upper part of the tube. 
These white specks all proved to be Copepods, which, when 
examined under the microscope, were without exception found to 
belong to the species mentioned above, viz. Lichomolgus hirsutipes. 
Though we have not yet been able to ascertain if Lichomoleus 
hirsutipes is only to be obtained in the Firth of Forth associated 
with this Annelid, or whether it is associated with the same Annelid 
elsewhere in the British seas, the facts mentioned seem to indicate 
an association between the Copepod and Annelid not altogether 
accidental, and, if so, they may probably occur associated in the 
same manner in other localities where the conditions are suitable.
