F. B. REPORT, 1906. 



PLATE XI 



The figure is a reproduction of a photograph taken by Dr. Williamson through 

 the glass front of the tank, and shows the eggs and male in situ. The male lump- 

 sucker (a) occupies a position which he often took up, adhering to the side of the 

 tank abov-e the eggs. His outline is somewhat blurred, owing to movement while 

 the photograph was being taken. Very often he sat on the stone behind the eggs, 

 part of which is shown at b. The egg-masses which he is guarding and attending 

 to are shown at c, c. The anemone, which was his constant companion, is repre- 

 sented at d.
