a 7}'/<7, but there are too many tentacles for a Tima, and the size and shape remind one very much of 

 Eutontna. Bedot in his Histoire des Hydroides includes "Geryonopsis Forbesif among the synonyms 

 of Irene viridula Per. & Les. Peach (1868, p. 97) mentions a medusa, "Tima Forbesit\ which is said to 

 be distinguished from Tima bairdti by the possesion of numerous tentacles; probably also this medusa 

 belongs to Eutontna indicans. The same may be the case with a medusa mentioned by Crawford 

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

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