Wright appears to have overlooked the 

 fact that Forbes and Goodsir had previously 

 described this medusa from the Sound of 

 Mull, Scotland, in 1853, under the name 

 Plancia gracilis. The medusa described by 

 Forbes and Goodsir is 8 mm. wide, has 

 about 60 cirri, and 2 long tentacles about 

 as long as the bell-diameter. The peduncle 

 is about 1.5 times as long as the bell-radius. 

 The stomach is small and flask-shaped 

 with 4 short, simple lips. The stomach is 

 pink. For description of S. gracilis based 

 upon the accounts of Haeckel, Cunningham, 

 and Browne, see synoptic table of the species 

 of Saphenia.
