CELLULARINE AND OTHER POLYZOA. 317 
■Stirparia, Goldstein, 1880, Q. J. Micr. Soc. Vict. Proc. i. p. 75. — Genotype (the only- 
species), StiijpaHa aiinulata [Bicellaria annulata, Maplestone, 1879, t. cit., 
p. 19). The generic name is pre-occupied, for Pennatulacea, by Leuckart, 
1841, Zool. Bruchstiieke, ii. p. 122 ; and I propose that it be replaced by 
Stirparidla (nom./nov.), with the genotype Stirpariella annulata (Mapl.). 
Stirjpariella, nom. nov. — See Stirparia. 
Stolonella, Hincks, 1883, A. M. N. H. (5) xi. p. 197. — Genotype (the only species), 
Stolonella clausa, Hincks, n. sp. 
.Synnota, Pieper, 1881. — See Sijnnotum. 
■Synnotum, Pieper, 1881, Neunte Jahresb. Wostfiil. Provinzial-Ver. pro 18S0, p. 47. — 
Pieper suggested the alternative names Mononota and Sijnnota for a single 
new species, Gemellaria (?) avicularis. Synnota was adopted, but amended to 
Synnotum, presumably on etymological grounds, by Hincks, 1886 (A. M. N. H. 
(5) xvii. p. 255) ; and I think this change in spelling may be accepted. 
Waters (1897, J. L. S. xxvi. p. 15) pointed out that S. aviculare is probably 
a synonym of Loricaria mgyptiaca, Audouin, 1826, p. 243 ; and I have 
satisfied myself that this conclusion is correct. The name of the genotype 
should thus be Synnotum cegyptiacum (Aud.). It does not seem to have 
occurred to other authors that this species cannot be placed in the same genus 
as Eucratea loricata (Linn.). See Eucratea and Gemellaria. 
Ternicellaria, D'Orbigny, 1851, P. F. T. 0. pp. 40, 47 ; see also 1852, A. S. K. (3) 
xvi. p. 330. — Genotype (the only species), Ternicellaria aculeata {Bicellaria 
{Tricellaria on pi. 2) aculeata, D'Orb., 1839-1846, Voy. Amer. Merid. 
V. 4, p. 8). Synonym of Tricellaria. 
Tricellaria, Fleming, 1828, p. 540. — Genotype (the only species), Tricellaria ternata 
(Cellaria ternata, Ellis and Solander, 1786, p. 30). 
Ulidium, Searles Wood, 1844, A. M. N. H. xiii. p. 17. — Genotype (the only species), 
Ulidium charlesivortkii (Melicerifa charlesworihii, Milne Edwards). The prin- 
cipal reasons given for its introduction are that Melicerita is etymologically 
incorrect, Melicertina is objectionable, and names similar to Melicerita have 
been used in other groups. Synonym of Melicerita ; see also Melicertina. 
■Unicellaria, de Blainville, 1830, p. 425 ; see also 1834, p. 461. — Genosyntypes, 
Sertularia chelata, L. (as described by Ellis, 1756, Hist. Kat. Cor. French Ed. 
p. 57), /S. cormita, L., 1758 (p. 810), Eucratea appenclicalata, Lamouroux, 1821 
(p. 8), and Lafoea lafoyi, de Blainville, nom. nov. for Lafoea cornuta, 
Lamouroux, 1821 (p. 8). The first of these species is referable to Scruparia, 
Oken, 1815; the second and third to Crisia, Lamouroux, 1812; and the 
fourth appears to be a Hydroid. 
Watersia, Levinsen, 1909, pp. 94, 99. — Genotype (the only species), Watersia 
militaris {Plustra militaris. Waters, 1887, A. M. N. H. (5) xx. p. 93).
