CELLULAEINE AND OTHER POLYZOA. 313 
Melicerita. — The introduction of this genus b}' Milne Edwards (1836, A. S. N. Zool. 
(2) vi. p. 347), with only one species given merelj' as " Melicerite de 
Charlesworth," was not strictlj' in order. Searles Wood (1844 ; see Ulidium) 
quotes this as Melicerita charlesivortldi, -which was thus regularized, and hecame 
the genotype. His simultaneous introduction of Ulidium, with the same 
genotype, was unnecessary. In the A. S. N". (3) xvii., dated 1852, but probably 
published later, D'Orhigny refers to the species as M. charlesvortliii. 
Melicertina, Ehrenberg, 1839, Phys. Abh. Akad. Wiss. Berlin, J. 1838, Tab. ii.— 
Proposed to replace Melicerita, which " ist nicht sprachgemiiss." This 
emendation need not be accepted. 
Membranicellaria, Levinsen, 1902, Vid. Medd. naturh. Foren. Copenhagen, 1902, 
p. 22 n. — Introduced for Melicerita dubia, Busk (1884, p. 97) and a number 
of Cretaceous species, which are indicated. Genotype, now selected, Membrani- 
cellana dubia {Melicerita dubia, Busk). Levinsen subsequently (1909, p. 207) 
described M. dubia, from part of Busk's original material, but he gives 
M. d'dbia. Busk, as a doubtful synonym. His reason for inserting a query is 
not apparent, but if it should prove that two species were included in Busk's 
material the form described by Busk would be the genotype, as no other was 
indicated in Levinsen's original account. 
Menipea, Lamouroux, 1812, p. 183. — Genosyntypes, Gellaria cirrata, Ellis and 
Solander (1786, p. 29), quoted by Lamouroux as cin-Jiata, and G. Jlabelluni, 
Ell. and Sol. (1786, p. 28). Genolectotype, Menipea cirrata : see Schweigger, 
1819, Tab. 8 ; 1820, p. 428. The reasons given by Marcus (1922, 
p. 11) for regarding M. cirrata as a synonym of Gellidaria crispa, PaUas 
(1766, p. 71) seem to me sufficient. Pallas gave the locality as " Oceanus 
Orientalis," but on p. 72 he states that it was found with a Fucus qualified 
by the adjective " capensis," which presumably meant the Cape of Good Hope, 
as explicitly stated in the German Edition (1787, i. p. 107) of Pallas' work. 
Seba's figure (Thesaurus, iii. PI. 101, No. 8) is hardly demonstrative, as it is 
stated to be by Marcus, but it may have referred to the species which was 
later described by PaUas, who gives this reference. The correct name of the 
genotype appears to be Menipea crispa (Pall.). Waters' selection (1897, 
J. L. S. xxvi. p. 2) of M. bushii, Wyv. Thorns, (see under -jPrnma, in Sect. V.) 
is obviously invalidated by the fact that this species was not included by 
Lamouroux. 
Mononota, Pieper, 1881.— See Synnotum. 
Monsella, Canu, 1900, Bull. Soc. Geol. France (3) xxviii. p. 437. — Genotype, selected 
by the author, Monsella eoeena (Planicellaria eocena, Meunier and Pergens, 
1886, " Les Bryozoaires du Systeme Montien (Eocene Inferieur)," Louvain, 
privately printed, p. 7). Canu gives figures of this species, copied from 
Meunier and Pergens.
