308 SIR SIDNEY F. HAEMER ON 
Eucratia, Fleming, 1828, p. 541. — Used by mistake for Eucratea {q. v.). 
Eaoplozoum*, n. gen. — Genotype, Euoj>lozoum cirratum (Cellidaria cirrata, Busic,. 
1884, p. 17). 
Zoarium erect, attached by a basal tuft of rootlets. Branches biserial, the 
zooecia large and obliquely alternating, all facing in the same direction, their 
proximal portions narrow, their distal portions expanded, the frontal membrane- 
occupying the entire surface of the expanded portion. Bnsal walls of zooecia 
strongly convex. Branches traversed by oblique joints, each zooecium being 
crossed by one joint near its proximal end and by another at the commence- 
ment of its expanded portion. Avicularia of two kinds, the smaller at the- 
distal outer border of the zooecium, and a very large kind (present on only a 
few of the zooecia) arising from the inner border. Strong flexor zooecii 
muscles present, by which the branches are inflected. Ovicells ver}' large.. 
Bifurcation of type 6 (PI. 16. fig. 6). 
It can hardly be doubted that this very remarkable species, which was- 
placed by Busk in a heterogeneous assemblage referred to Celliilaria, deserves 
recognition as the type of a new genus. It was described recently, by the- 
late Miss Alice Robertson (1921, Eec. Ind. Mus. xxii. p. 39), as Kinetoskias 
arahianensis, Roberts., n. sp. 
Euthyris, Hincks, 1882, A. M. N. H. (5) x. p. 164. — Genosynt5'pes, E. ohtecta, Hincks,, 
n. sp., Flustra homhycina, Ellis and Solander (1786, p. 14) and Carhasea 
episcopalis, Busk (1852 ^, p. 52). G. episcopalisis the genotype of EutJiyroides,. 
Harmer, 1902. F. bombycina Ell. and Sol. (nee Busk ; see Oiwhoporella)^ 
which appears to be at present unrecognizable, is the genotype of Semijlustra, 
D'Orbiguy, 1852. Euthyris ohtecta is thus left as the genotype of Eathyris, 
but if F. bombycina could be recognized it would probably become necessary to- 
regard Euthyris as a synonym of Semiflustra (q. v.). 
Eiithyroides, Harmer, 1902, Q.J. M.S. xlvi. p. 280.— Genotype, selected by the 
author, Euthyroides episcopalis {Carhasea episcopalis. Busk, 1852^, p. 52). 
Falcaria, Oken, 1815, p. 91. — Genosyntypes, Cellidaria falcata (Pallas, 1766, p. 76), 
s. coniuia (Sertidaria cornuia, L., 1758, p. 810), C ehiirnea (S. ehurnea, L., 
1758, p. 810) and C. anguina (S. anguina, L., 1758, p. 816) ; the first two 
referable to Crisia, and the third to Aetea, two genera introduced by 
Lamourous in 1812. Gray (1848, p. 136) selected Falcaria cornuta as the 
genotype. Synonym of Crisia, Lamx., 1812, and pre-occupied in Lepidoptera 
by Falcaria, Haworth, 1809, Lepid. Britann. p. 152 ; for date of publication 
of which sec Woodward, vol. ii. p. 804. 
Farcimia, Fleming, 1828, p. 534. — Genotype (the only species), Farcimia fistidosa 
(Eschara fistulosa, L., 1753, p. 804). There is no justification for including 
Nellia ocidata, Busk (see Ncllia) in this genus, as has been done by Waters 
(1887, A. M. jST. H. (5) xx. p. 92) and others. Synonym of Cellcma, Ell. and 
Sol. 1786.
