Report of the Marine Zoological Section, 1013. 



Once more I have to deplore the lack of interest shewn 

 by our members generally in this branch of our Society. Only 

 one rare " find " has been reported to me during the past year, 

 and that by two of our junior members — the Misses M. Carre 

 and C. Dorey — of some specimens of one of the rare Crelente- 

 rata — Lucernaria Campanulata. These were exhibited at one 

 of our meetings. 



In August I came across a remarkably fine specimen of 

 ..one of the Polyzoa — Lepralia Foliacea — which is very rare 

 here. It was fixed to a rock in one of the inner Gouillot 

 caves in Sauk. 



Phosphouescence of the sea in the summer owing to the 

 presence of minute organisms is very common, but the scene 

 I witnessed in Sauk Harbour one evening last August was so 

 exceptional as to be worth recording. 



Going down late one evening to obtain sea water for 

 the stock of animal life I had been collecting I found the 

 whole harbour most brilliantly illuminated by myriads of 

 phosphorescent points. On filling my bucket with water the 

 phosphorescence still continued in the bucket, particularly if 

 the water was agitated. The light was given oft' by medusoids 

 — little transparent masses of jelly, each a living animal and 

 an early stage in the development of the medusae or jelly-fish. 



For a number of years I have kept a large and several 

 smaller marine aquaria, and some observations I have made 

 may be interesting. 



Of the fishes I have kept I have found the little Smooth 

 Blenny — Pholis Icevis or Bletmius pkolis — and the Butterfly 

 Blenny of our rock pools the most interesting and the most 

 easily tamed. Naturally they are very pugnacious, but they 

 very soon learn to take food from your fingers and even to 

 jump out of water on to a rock to be fed. One, which I 

 kept for several years and have now returned to the sea, 

 showed no objection to being handled, and would even take 

 and eat a piece of limpet while I held it in my hand. A 

 peculiarity of this fish is that it will voluntarily leave the 

 water and will spend several hours perched on top of a rock.
