LEPTOMEDUS/E — EUTIMA, EUTIMIUM. 



305 



close to the stomach. Peduncle well developed, narrow, tapering, and reaching slightly 

 beyond the velar opening, being about as long as bell-radius. Stomach short, 4 slightly fim- 

 briated lips. The stomach and gonads are opaque white, the tentacle-bulbs green. Common 

 at the Bahamas and Tortugas in spring and winter months. Hydroid unknown. 



Eutima pretiosa. 



Eutimalphes pretiosa, Haeckel, 1879, Syst. der Medusen, p. 195, taf. 11, fig. 8. 



Bell flatter than a hemisphere, 40 mm. wide. 60 to 80 short, crumpled tentacles, with 

 thick, conical basal bulbs. Numerous cirri; a few marginal warts are scattered between the 

 tentacles. 8 large lithocysts, each with 16 to 20 concretions. Peduncle thick and pyramidal, 

 about as wide as the bell-radius at its base and as long as wide. Stomach large, with 4 

 very large, recurved lips with curtain-like, complexly folded margins. Each lip is about as 

 long as bell-radius. 4 linear, folded, curtain-like gonads occupying nearly the entire lengths 

 of the 4 radial-canals. Described by Haeckel from a preserved specimen found off the coast 

 of Australia. (See text-figure 169.) 



Genus EUTIMIUM Haeckel, 1879, sens. ampl. 



Eutimium + Octorchidium, Haeckel, 1879, Syst. der Medusen, pp. 190 195.

The genus Eutimium was founded by Haeckel, 1879, for E. elephas of the German 

 Ocean, but this has marginal warts and should be called Eutima. 



GENERIC CHARACTERS. 



Eucopidae with 8 lithocysts, 2 in each quadrant, and with 4 or more tentacles. There are 

 neither cirri nor -warts upon the bell-margin or upon the sides of the tentacles. The gonads 

 are developed upon the 4 radial-canals. There is a well-developed peduncle. In some species 

 there are 8 gonads, 2 upon each radial-canal; in others, however, there are but 4 gonads, one 

 upon each radial-canal.

 Annual Report Fishery Board of Scotland. 



Haeckel, 1879, restricts Eutimium to include only those forms with 4 tentacles which 

 have 4 gonads, one on each radial-canal. He applies the generic name Octorchidiutn to 

 embrace those forms which have 8 gonads, 2 on each radial-canal. 



Eutimium is very closely allied to Eutima, but lacks the warts or cirri which characterize 



the latter genus.
