a Tima, but there are too many tentacles for a Tima, and the size and shape remind one very much of 

 Eufoiuiin. Bedot in his Histoire des Hydroi'des includes '•^Geryonopsis Forbcsii" among the synonyms 

 of Irene viriditla Per. & Les. Peach (1868, p. 97) mentions a medusa, ^'■Ti'via Forbcsir\ which is said Xo 

 be distinguished from T/'um baird/i by the possesion of numerous tentacles; probably also this medusa 

 belongs to E/ffoni/ia iiid!ca)is. The same ma\- be the case witli a medusa mentioned b\- Crawford 

 (1891, p. 296): "A form evidently allied to Tinia, but with shorter peduncle, with more numerous tent- 

 acles, and with the reproductive organs only on a portion of the canals . . .".
