ample was often fixed to the glass by its ectoderm, which ap- 

 parently had very minute or granular suckers. 



Swarms of an Edwardsia occur in the stomach of the 

 flounder. 



Genus 6. Cerianthus, Delle Chiaje. 



Cerianthus Lloydii^ Gosse, Brit. Anem. p. 268, pi. 7. fig. 8, 

 and woodcut, p. 269. 



Procured at low water from the margin of the East Rocks, 

 and occasionally thrown on the West Sands after storms. A 

 splendid specimen from the latter (measuring Ih inches long 

 and as thick as a finger) in February discharged a vast num- 

 ber of ova after a week's confinement. The majority of these 

 bodies were rather coarsely granular, ovoid in form ; and some 

 had minute papillae at one end. No cilia were present, so 

 that in all probability they were dead. Both examples had 

 the first series of tentacles of the usual brown colour, with 

 about four faintly marked whitish specks on the inner surface. 

 The second series were uniformly brown.

Pennatula phosphorea, L. ; Johnst. Brit. Zooph.

Abundant on muddy ground in deep water, and often 

 brought up on the lines of the fishermen. 



Genus Virgularia, Lamck. 

 Virgularia mirabilis^ L. ; Johnst. Brit. Zooph. p. 161, pi. 30. 

 Occasionally in the stomach of the cod. 



Fam. Alcyoniadae.

Alcyonium digitatum^ L. ; Johnst. Brit. Zooph. 

 p. 174, pi. 34.

 rocks and stones between tide-marks. Often thrown in large 

 quantities on the West Sands after storms, attached to various 

 submarine structures.
