PENNATULIDA. 39 



«elegans» and of abyssicola> rather different; but this is due, partly to the colour, partly to the 

 different degree of retraction of the polyps and their tentacles, partly also, to the distance between 

 the consecutive pairs of wings. All such features are individually varying, e. g. compare Rolliker's 

 figures of St. elegans with those of Koren and Danielssen; both are true to life as I can certify 

 from the respective original specimens. As to D. borealis , its right as a separate species rests 

 on one single spicule! That a separate species cannot be maintained on such a character will 

 be admitted by all who have compared, for instance, a number of specimens of Funiculina qua- 

 drangular is. 



Distribution. This form is known from the coast and fjord-regions of Norway, from Rofoten 

 and down through the Skager Rak, in the deep channel of which it seems to be common (found by 

 the German North-Sea Expedition of 1872 and by the Gunhild ); further, it is known from a locality 

 north west of the Hebrides (west of Rona) ( Triton-); to these localities must now be added the 

 Yestman Islands, and thus its territory to the west is considerably extended, and it is quite probable 

 that it will also be found elsewhere. Its bathymetric range is between 30 and 550 fathoms; at the 

 Yestman Islands it has been found at 68 fathoms together with Virg. mira bill's and V.cladiscus. 



On the American side of the Atlantic, and only in the south, are as yet only Styla tula-species 

 having true wings with many polyps known (further particulars are wanting of the Sfylatula-species 

 taken by the Albatross » on the eastern coast of North America, off Chesapeake Bay, at a depth of 

 444 fathoms; Verrill: Am. J. Sc. Vol.29, p. 150, 1885).

This Pennatulid is said to have been taken at Iceland and brought to the Paris Museum by 

 Gaimard 1839 (Roll. Monogr. p. 243). According to its known distribution, its occurrence at Iceland 

 was verv probable, though up to the present we have had no other authority for it than the 

 above. From the results of the Ingolf , however, I am able to confirm the correctness of this 

 occurrence. At one of the stations south of Iceland (St. 47) the « Ingolf: has taken four specimens 

 of a Pennatulid which, after a thorough examination, I can state positively to be young stages of a 

 Pavonaria, and to belong without doubt to the species P. finmarchica.
