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 Sabella. 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 Alcyonium. In 

 some instances these tubes contained the living Annelid, but several 

 of them were empty. It was only when fishing in moderately deep 

 water 15 to 20 fathoms or so that these large worm-tubes were 

 obtained. Though the Alcyonium had usually spread itself over a 

 large 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 Lichomolgus 

 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.
