The Eev. H. Seddall to whose work " Malta 

 Past and Present" reference should be made, says: 

 "Zoophytes of many species are easily found in 

 the rock pools, and growing on the quays of the 

 harbours. Of these Anthea cereus is by far the 

 most common, with its long and finely coloured 

 tentaculae, which are not contractile within the mantle 

 of the animal as in the true anemones (Actinia)." 

 No fewer than seventeen kinds of anemones 

 may be met with, the scarlet variety of Actinia 

 wesembryanthemum being not uncommon round the 

 rocks in sheltered pools. Sertularia, Flustra, Goryo- 

 nia, Gelepora, Lepralia, Garyophyllia, with many 

 other genera are represented. Amongst the Chelen- 

 terata we must mention Pelagia noctilica, which is 

 now and again phosphorescent, especially during a 

 storm and at night. Rhyzostoma pulmo must not 

 be forgotten, nor the remarkable Charybdia marsu- 

 pialis so named from having on the abdomen a 

 curious purse, which is by some supposed to be a 

 food receptacle. Porpita mediterrunea strews the 

 beach at Marsascala after a gregale.
