Anthomedus^. 



Among the Ctenophorse Bero'e and Gydippe were common 

 in August, and remained during the autumn and early 

 winter. As these lessened in numbers Lesueuria, absent 

 before, made its appearance. On 21st January there were 

 several Lesueurice and one Bero'e. Shortly afterwards all 

 three vanished, and have not yet reappeared. 



Tiara octona and Margelis ramosa {Bougainvillia hritannica^ 

 Forbes) were fairly numerous during August. A specimen 

 of the former was captured as late as 7th October. 



Godonium pulchellum [Sarsia pulchella, Forbes) was found 

 only sparingly till towards the close of September, when it 

 was extremely abundant and ripe. After the winter's 

 absence a single young individual was captured in May. 

 The peduncle protruded considerably beyond the velum, and 

 the stomach was greatly distended with food. 



Among the more interesting of the Anthomedusge was 

 Euphysa aurata^ of which many were brought in during 

 August. This form had the characteristic single abnormally 

 developed tentacle and the three bulbs. In no case were 

 there tentacle rudiments distinguishable from the bulbs. In 

 addition to the scarlet spot on each yellow ocellus, a scarlet 

 ring ran round the umbrellar margin. 



A single specimen of Godonium gemmiferum [Sarsia gemmi- 

 fera) was captured on 16th August. This was a specially 

 interesting form. The peduncle was much longer than, 

 nearly six times the length of, the umbrella, a condition 

 not mentioned by Forbes. It was beset along its course with 

 spirally arranged buds in different stages of ripeness, and 

 terminated in a bottle-shaped stomach. 



Hyhocodon seemed to be over for the year, as not a single 

 individual appeared in August. It had been plentiful about 

 June, which seems to be its season. Many specimens were 

 preserved in the laboratory, showing that process of budding 

 at the base of the single tentacle from which it gets its name 

 of humpbacked.
