about 2 feet in diameter ; the combined lengtli of the umbrella 

 and arms about 4 feet. The colom- of the umbrella was pale 

 gi'een, with a deep reddish margin. Ai-ms bright blue. 



In 1896, a specimen was captured by Mr. F. W. Gamble on 

 September 1st, between Bray Head and Puffin Island. Mr. 

 Gamble informs me that slightly over a hundred young Horse- 

 Mackerel ( Caranx trachurus) were seen sheltering under the 

 umbrella. When first seen the little fish formed a zone as 

 they hovered round the Medusa. On the captui-e being made 

 with a bucket the fish were found hidden away in the sub-genital 

 pouches. The size of the fish varied from 16 to 45 mm. in 

 length ; they were sent to Mr. E. W. L. Holt for identification 

 (Holt, 1895, Journ. Mar. Biol. Assoc, p. 119 and p. 340). The 

 association of young fish with RJmostoma has been noticed by 

 Gadeau de Kerville (1894) at Granville. The same species of 

 fish was also found by him. Some other specimens of HMzos- 

 toma were seen off the mouth of the harbour early in September 

 by Mr. W. I. Beaumont. Some of these were also accompanied 

 by little fish. 



In 1897-98, none were seen.
