356 BRITISH NAKED-EYED MEDUSiE. 



many tentacula are suspended. The central peduncle or stomach 

 is campanulate, and opens widely by four scarcely undulated lips ; 

 and it probably may contract itself into four or six divisions. 

 Forbes took his specimens in Penzance Bay in 1836, and in Oban 

 Bay in 1845. — -Mine were taken, in July and August, 1849, in 

 Fowey Harbour. They had also six ovaries around the base of 

 the stomach ; and from each of these ran a gastro-vascular canal, 

 which divided into two, once only, before reaching the margin; 

 there were thus only twelve ocelli hulhs, from which were suspended 

 as many tentacula ; these were stout and short, and had one stiff 

 curl in each. The tentacula figured by Forbes were much longer, 

 and slightly waved, but not curled. The central peduncle, or 

 stomach, in mine was campanulate, had four rather pointed and 

 undulated lips, and, in addition, at the junction of the lips with 

 the stomach, four rounded ball-like projections. The ovaries were 

 filled Avith ova, shewing the adult state. The colours in both 

 were much alike, '^ 



I have, at various times, obtained in Scotland the following 

 new beauties; they are of suflficient interest to warrant their 

 being made widely known ; and as, although they have been sub- 

 mitted to the Edinburgh Physical Society, they have not yet been 

 published, I trust a notice of them here may not be unacceptable. 



The first is a Tima.f I have dedicated it to the memory of 

 my late friend. Professor Edward Forbes, as Tima Forhesii. I got 

 it at Peterhead in 1853, The umbrella is hemispherical, smooth, 

 transparent, and colourless ; the margin fringed with numerous 

 tentacula, alternately longer and shorter. % Four radiating vessels 

 run down the sub-umbrella, and open into a circular marginal 

 one. Peduncle large and cylindrical, extending a little below the 

 margin ; the gastric vessels run down it to the constricted point 

 and join the campanulate stomach, which opens by four large tri- 

 angular lips, covered on the edges by rather long and numerous 

 fimbriated appendages. The reproductive glands are four, one on 

 each radiating vessel ; these glands are traversed by spiral threads 

 amongst the ova. Tima Forhesii differs from T. Bairdii in having
