CELLULARINE AND OTHER POLYZOA. 309 
Farcvminaria, Busk, 1852", p. 32. — Genotype (the only species), Farciminaria aculeata. 
Busk, n. sp. 
Filicella, Searles "Wood, 1844, A. M. N. H. xiii. p. 15. — Genotype (the only species), 
Filicella miguinea, S. "Wood, n. sp., a Crag species, possibly the adnate part of 
a species of Aetea. 
Fistulana, 0. F. Miiller, 1 776, Zool. Dan. Prodr. p. 282.— In his Corrigenda (p. 282), 
Miiller states that Fistularia, introduced in the same work, is to he changed to 
Fistulana, a course which was probably adopted because Fistularia was pre- 
occupied, in Pisces, by a Linnean genus (1758, p. 312) of the same name. 
Fistularia was introduced by Miiller, without figures, on p. 254, with the 
genosyntypes F. ramosa (Tubularia ramosa, L., 1758, p. 804; 1767, p. 1302), 
F. riiuscoides (T. muscoides, L., 1767, p. 1302), F. simplex, F. longicoriiis and 
F. niulticornis, Miill., n. spp. In 1780, Fabricius (Fauna Groenl. p. 441) uses 
Fistidana for F. ramosa and F muscoides, quoting the diagnoses of Miiller 
verhatim, iu words identical with those of Linnseus, 1767. In 1789, 
Abildgaard (in Miiller, Zool. Dan. iii. p. 15) describes and figures F. multi- 
cornis, quoting Miiller's diagnosis, with additions. 
Of Miiller's species, the first two are Hydroids, while the diagnosis of 
F. longicornis suggests a Polychoete (Spionid). F. simplex may be a Ctenostome 
Polyzoon, while it seems probable, from Abildgaard's description and figures 
(pi. 90. figs. 1-3) that F. imdticomis was also one of the Polyzoa. Smitt 
(1868, pp. 279, 280) suggests that it might be identical with Aetea truncata, 
Landsborough (see Cercaripiora), but he points out, as an objection to this 
conclusion, that Miiller had described the tentacles as 30 in number. This is 
not quite correct, as Miiller described them as being " ultra viginti," and it 
was Abildgaard who stated that they were " ad triginta." In an earlier paper 
Smitt (1865, Ofv. K. Vet.-Akad. Forh. xxii. (1865), p. 13, pi. 3. fig. 4) had 
shown that Aetea truncata has 12 tentacles, and on this ground I think that 
F. midticornis cannot have been that spenies. Abildgaard's figures seem more 
likely to have been taken from a species of Nolella, Gosse {Cylindroeeiim, 
auctt. ; see Harmer, 1915, Siboga Rep. Polyzoa, i. p. 52). Fistidana should 
be disregarded for Polyzoa. The same name was introduced in other groups, 
by Bruguiere (1789) and Lamarck (1799) ; see Sherborn, Index Animalium, i. 
1902. 
Fistidaria, 0. F. Miiller, 1776, p. 254. — See Fistulana. 
Flahellaria, Gray, 1848, pp. 106, 146. — Genosyntypes, Sertidaria spiralis, Olivi,. 
1792 (Zool. Adriat. p. 291, pi. 6. figs. 2, a, a) and Flustra setacea, Fleming, 
1828 (p. 536), referable to Caberea. Bugida murraj/ana was given as a 
synonym of Olivi's species ; but the occurrence of this northern form in the 
Adriatic seems to be very unlikely, and Olivi's species ought probably to be 
placed elsewhere in Bugula. Gray's genus thus appears to be unnecessary. 
It may be remarked that Flahellaria, Lamarck, 1816, p. 342, is used for 
certain calcareous Algae.
