T. larynx on the other hand had fully mature hydranths, 
evidently shedding their larvae ; for I found many newly fixed 
actinulae, and many well developed larvae still in the gono- 
phores ; but I was unable to find any free larvae in the plankton 
of the bay. This was probably due to the fact that there are 
very strong currents around the Sker Rock* which would 
carry the larvae rapidly away. ’ 
‘“‘ Tubularia can be obtained only at very low tides, and 
lives only for a few days in the tanks at the Biological Station ; 
so for nearly a week in the middle of my visit I had no living 
material. During this time I examined in the laboratory 
about half a dozen different series of sections through Tubularia, 
belonging to Mr. Chadwick at the Biological Station, and 
found many interesting problems which I shall attempt to 
solve during this winter with the aid of some long series of 
sections of my own which are now being made. 
‘“T gladly acknowledge the help afforded me by the 
Biological Station, both in connection with the collection of the 
necessary material, and also in the subsequent work upon it. 
I hope to complete the investigation m the University 
Laboratory of Zoology, at Liverpool.”
