MEDUS.E. I. lOl 



The present material augments the known area of distribution to comprise the west coast of 

 Norway at Aalesund and the fjords on the north-western part of Iceland. 



The Norwegian specimens as well as those from Patreksfjord in Iceland are found in the later 

 half-part of June. Tiie .species is said to occur off the east coast of Scotland from May to August. It 

 occurs at Heligoland from the end of March to the beginning of July and ma\' be carried into the 

 beach in enormous quantities. It is found in the Danish waters from the beginning of April to the 

 end of June. In May 1916 I saw enormous quantities at the surface of the water in Lillebelt. 



Genus Saphenia Eschscholtz. 



Saphenia gracilis (Forbes and Goodsir). 



Mayer 1910, Medusa of the World, p. 294. 



S\ii. Saphenia mirabilis (Wright) Haeckel. 



Bell hemispherical, about 15 — 20 mm wide. There is a long and thin, cylindrical gelatinous peduncle which may be 

 extended to a length of 5 - 10 times the diameter of the bell. The peduncle is entirel}- surrounded by the four linear gonads, 

 which extends from the base of the peduncle to the stomach; the latter is small, flask-shaped, with 4 small, recurved lips. Two 

 long, opposite tentacles and a large number of marginal warts and cirri. 8 adradial marginal vesicles, each containing about 

 3 concretions. Stomach and gonads delicatelv pink. 



British coasts and North .Sea 



Genus Eutima Mc Crady. 



Eutlma insignis (Keferstein). 



Mayer 1910. MedusiE of the World, p. 299 



Umbrella hemispherical, about 8 mm wide. The stomachal peduncle is once or twice as long as the diameter of the 

 bell, narrow, of equal width. Stomach about half as long as the bell-radius, flask-shaped, with 4 large lips. The gonads extend 

 from near the stomach upwards along the 4 radial canals on the peduncle; there are no gonads on the subumbrella. There 

 are 4 long perradial tentacles, each flanked by a pair of cirri; moreover there are about 30 rudimentary bulbs, likewise flanked 

 by cirri. S adradial marginal vesicles, each containing 2 — 5 concretions. The animal is colourless. 



British coasts and north-west coast of France. 



Eutima elephas (Haeckel). 



Mayer 1910, Medusa; of the World, p. 300. 



Umbrella about 16 — 20 mm wide; gelatinous substance thick The upper p.irt of the stomachal peduncle is broadly 

 conical; the entire length ot the peduncle is about 3 to 4 times the diameter of the bell. Stomach short, urn-shaped, with 4 

 recurved, slightly folded hps. 4 radial canals; the gonads are developed along the radial canals on the narrow part of the 

 peduncle. There are 4 long perradial tentacles and numerous minute warts on the bell-margin; no cirri; 8 adrndial marginal 

 vesicles, each containing about 8 — 10 concretions. Stomach, canal system, and tentacles green.

 Octorchis gegenbauri (Haeckel). 



.Syn. Eutima caiiipamitata (Claus). Mayer Igio, Medusce of the World, p. 302. 



Umbrella hemispherical, about 25 — 30 mm wide. Stomachal peduncle about as long as the bell-diameter, the upper 

 part broadlv conical. Stomach small, urn-shaped, with 4 folded lips. 4 radial canals; the gonads are developed partly along 

 the subumbrella part of the radial canals, partly on the peduncle about half-way between the base of the peduncle and the 

 stomach. There arc 16 — 32 long tentacles and about 120- 150 tubercles, flanked by cirri. 8 adradial marginal vesicles, each 

 containing 16 — 20 concretions. Stomach, canal-system, gonads, and tentacles greenish.
