particular difference; unfortunately the state of preservation does not allow a determination of the 

 number of concretions in the marginal vesicles. 



Material (see Chart XII): 



i) _ Myri Bngt, south coast of Iceland. July 27th 1904. 'Heskytteren", Gemzoe. - 2 speci- 

 mens, 37— 38 nun wide. 



2) — Lat. 63°i8' N., Long. 2i°3o' \\'., vSouth-Iceland. July 8th 1904. Depth 178 m. '•Tlior" staL 

 176(04). — 3 specimens, 22—28 — 35 nnn wide.

 Phialidiiiiii ishnidiciiiit from Iceland. 



The specimens from loc. No. 5 are very large, about 40 mm wide; both specimens have lost 

 the gastro-genital organs, btit these are regenerating; in one specimen three new stomachs are devel- 

 oping; a nematode is enclosed in the gelatinous substance near the three stomachs. 



As will appear from the above list of the material, this species has been found both south, 

 west, north, and east of Iceland; it is probable, therefore, that it is derived from a hydroid widely 

 distributed at the coasts of Iceland (possibh' Caiiipaiuilaria voluhilis?]. The specimens ha\'e all been 

 found in Jul>' or August.

Mayer 1910, Jledusce of the World, p. 2S5. 



Bell somewhat flatter than a hemisphere, about 13 mm vide. Gelatinous substance thick above, but thin at the side.s 

 of the bell. .Stomach short, with 4 well-developed lips. 4 linear gonads along the outer two-thirds of the 4 radial canals, not 

 touching the circular vessel. 16 — 30 long tentacles with well-developed, tapering basal bulbs, flanked by cirri. Cirri also arise 

 from the bell-margin between the tentacles. Marginal vesicles, each containing 5-10 concretions, alternating with the tentacles. 

 Gonads and tentacular bulbs light reddish-brown; on each interradial wall of the stomach there is a large black spot. 



The species occurs in the North-Sea, whence it is occasionally carried into the Kattegat
