T. ijiconspicua, Forbes, as a variety of Fhialidium varia- 

 hile, which was abundant at St. Andrews in June, 1889. 

 None exceeded a quarter of an inch in diameter, and all 

 were immature. 



Clubb {7) records Thaumantias convexa, Forbes {9) 

 which was found by Mr. I. C. Thompson, off Penmaenmawr, 

 in July, 1885. Hseckel considers T. convexa to be identical 

 with Fhialidium variabile. 



Eutima insignis, (Keferstein 15). 



Keferstein first described this medusa from St. Vaast, 

 Normandy, 1862. In 1893 I took an adult specimen at 

 Plymouth. It is a rare medusa and has not been 

 recorded from other localities. 



In the adult the umbrella is hemispherical, about 7 mm. 

 wide and 3^ mm. high. The manubrium is very long, 

 about 9 mm. Mouth with four large lips. The gonads 

 are on the radial canals, along the lower half of peduncle. 

 On the margin of umbrella there are four very long 

 perradial tentacles, about 20 mm. long when fully ex- 

 panded. At the base of each tentacle there is a pair of 

 cirri. About 30 bulbs are also evenly distributed upon the 

 margin, each with a pair of cirri. Eight adradial mar- 

 ginal vesicles, each with 2 — 5 otoliths. The medusa is 

 perfectly colourless. 



An early stage of this medusa was taken in Port Erin 

 Bay, 1893. Umbrella about IJ mm. in diameter. Four 

 large perradial tentacles, four interradial and eight adra- 

 dial bulbs. A pair of cirri at the base of each tentacle and 

 bulb. 



Saphenia mirahilis, (Wright 15). 



First taken by Strethill Wright in 1858 near Queens- 

 ferry, Firth of Forth.
