with regard to spiculation; the want of spicules in the tentacles of this species, stated by Kolliker, 

 is for instance in no way a constant feature, and will rarely, I think, hold good for young colonies. 



Distribution. The species has been found on the Norwegian coast, at least from Trondhjem 

 Fjord to into the Christiania- Fjord; also in the Skager Rak, in the deep channel of which it is evidently 

 numerous (many specimens, both large and small, have been taken in 1897 by Dr. J oh. Petersen; 

 comp. Vid. Medd. Nath. For. Kbhvn. 1898, p. 1 ; main- specimens have later been taken at the same 

 locality by the steamer Thor ); at Bohuslan; the west coast of Scotland, the Hebrides; midway 

 between the Hebrides and Sudero; the Fseroe Channel, in the warm area (among others by the «Michael 

 Sars , 1902); the Atlantic, west of Brittany (48 26' N. Lat. 9° 44' W. Long., K611. Monogr. p. 369), and 

 nearer the coast of Brittany, as also off Arcachon (P.Fischer, Bull. Soc. Zool. Fr., vol.14, P-34); a l so m 

 the northern part of the Bay of Gascony I Trichoptilum sp. Roule, Camp, du Caudan , p. 307); the 

 Mediterranean (Golfe du Lion, Naples, Adriatic Sea). To these localities is to be added the American 

 side of the Atlantic [P. armata Yerr.) from Sable Island to in the Carribbean Sea (Verrill). 



The new localities, the stations of the Ingolf Nr. 40, 62 c N. Lat, 21 36' W. Long., and Nr. 18, 

 61° 44' N. Lat, 30° 29' W. Long., and the station of the Thor Nr. 167, 63° 5' N. Lat, 20 7' W. Long., 

 accordingly extend the European distribution of the species in a way that can only serve to bear 

 out my supposition of the identity of armata with quadrangular is. 



In the Atlantic the species is thus known so far, only north of the equator and inside 

 the territory of the positive bottom temperatures l ). The depths are given as from 10 — 30 fathoms 

 up to 769 fathoms; the above mentioned stations of the < Ingolf » exceed the greatest depth hitherto 

 known, one being 845 fathoms, the other 1135 fathoms. According to what is stated above, the 

 species, outside the Atlantic, may occur at New-Zealand, at a depth of 700 fathoms; but at all events 

 it is certain that the genus Funiculina belongs also to the Indo-Paeifie Ocean, the young stages of 

 Leptoptihuii and Trichoptilum having been taken there by the Challenger in two widely separated 

 localities, both south of the equator.

In one locality, south of Iceland, the Ingolf has taken one complete and five more or 



less incomplete specimens of a Protoptilum which is to be referred to the form P. carpenteri Koll. 



') On PI. II, figs. 3, 3 a of the Chall. Report on the Alcyonaria (vol. 31, 1S891 Wright and Studer — among the 

 Strophogorgise, however — have figured a fragment of a « Trichoptilum , which, in their opinion, is perhaps a new species of 

 this genus . The very incomplete specimen has been taken at Station 143 of the Challenger'-, off the Cape of Good Hope. 

 The figure shows only three developed polyp-calyxes, and no incomplete polyps or zooids whatever, and just as little the form 

 of the calcareous axis: neither is anything said of the latter in the explanation. To judge from the figure the question may 

 be of a Funiculina, but it is impossible to decide whether it is F. quadrangularis.
