is identical with V. mirabilis. It is said to resemble V. multiflora Kner, and to have its, < calicles aussi 

 profondement separes que cenx des V. mirabilis Mull. (Bull. Soe. Zool. de France, vol. 14, pp. 36, 37); 

 but a more particular description of it is wanting. 



With regard to the distribution, I have to add here a new locality of no small interest, 

 viz. the Vestman Islands off Iceland. During the summer of 1900, about fifty large and small frag- 

 ments of specimens with wings with 4 — 9 polyps were taken here, also 14 young stages, most of them 

 with 3 polyps in the wings (the Diana , A. C. Johansen), and in the summer of 1901 the Museum has 

 received from Th. Jonsson, physician in the Vestman Islands, a large fragment (145™™ long) with (8 — 9) 

 polyps in the wings. Hitherto J', mirabilis was only mentioned from the coasts of Scandinavia, Den- 

 mark and Great Britain. On the west coast of Norway it reaches as far north as Lofoten (Grieg, 

 1. c. p. n), on the British coasts it does not seem to have been found farther north than Scotland; in 

 the Danish seas its southern boundary is given as the Great Belt and the Sound down to south 

 of Hveen (Levinsen, Hauchs Togter, p. 399); for England, in the Channel (Falmouth and Eddystone, 

 Marshall: Oban Penn. p. 75, W. P. Marshall (sen.): Jouru. Mar. Biol. Ass., vol. III. p. 335). The fact 

 of this species having now been found at the Vestman Islands not only removes its northern boundary 

 and considerably extends its western territory, but, when we consider that in recent years we have 

 been able, just at the Vestman Islands, to point out several Atlantic animals known as belonging to 

 the fauna, partly of the south-west of Europe, partly of the Azores, the probability that the « V. Ljung- 

 maiini ■ taken at the Azores and in the Bay of Gascony is identical with V. mirabilis rises almost to 

 a certainty. If my supposition that V. vntitiflora is also to be referred to mirabilis, be correct, the 

 Mediterranean will also belong to the territory of the species, the Adriatic at all events where V. multi- 

 flora has been taken in the Bay of Fiume (at the island of Veglia) 1 ); also at Naples (Nisida) has a 

 Virgularia been found (Kolliker, Monogr. p. 369), but of its more particular determination nothing is 

 as yet known; also at southern France, Cap Beam (Lacaze Duthiers, Comptes rend. Acad. Sc. 

 1891, and Corallaires du Golfe du Lion, p. 359). On the American side of the Atlantic the species 

 has not hitherto been found, according to existing statements; but according to what has been said 

 above of V. Lyungmanni K611. it no doubt occurs there also, since 15 specimens of V. <s.Ljungmanni 

 were taken already in 1872 at a depth of 200 fathoms in the Gulf of St. Lawrence north east of Cap 

 des Rosiers (Whiteaves I.e. p. 34). 



The depths at which V. mirabilis has hitherto been found seem not to exceed 150 — 200 fathoms. 

 At the Vestman Islands it has been taken at 98 fathoms (the «Diana» St. 41) and at 49 fathoms (the 

 Diana St. 18).
