CELLULARINE AND OTHER POLYZOA. 305 
Ghlidonia, Lamouroux, 1824, p. 192. — Lamouroux states that Savigny's species (see 
below) appears to be the Vorticella polypina " des auteurs," and the author 
he had specially in mind may well have been Esper, who uses this name in 
Th. ii. of the Forsetz. d. Pflanzenth., Vorticella, PL 1. figs. 1, 2. The text of 
this part of the " Fortsetzungen " ends with p. 48, and it contains nO' 
description of the plate in question. It was published in two Lieferungen, 
9 and 10, in 1798 and 1806, respectively. The plate presumably appeared 
between 1798 and 1810, the date of Esper's death. 
The name " Chlidonies" was used by Savigny (Description de I'flgypte), at 
the foot of his PI. 13, in which figs. 3'-3' give admirable representations of 
what is almost certainly the same species as Vorticella pohjpina, Esp. 
Audouin, in his "Explications" (1826, p. 243) of Savigny's plates, did not,, 
however, accept Savigny's name, as he describes the species figured as 
Eucratea cordieri . Lamarck (1816, p. 140) introduced a new name, Cellaria 
vesicidosa, with Vorticella 'polypina, Esp. as a synonj'm, but with a query; and 
Hammer (1829, in Esper, Pflanzenth. iii. Lief. 16, p. 255) uses Eucratea: 
vesiculosa in describing Esper"s plate. Lamarck's trivial name antedates 
Audouin's, but Bertoloui (1810, Ear. Ital. Plant., Decas Tertia, p. 112; see 
also 1819, Amoen. Ital. p. 273) had previously described the same species 
as Cellaria pyriformis, in both papers giving a recognizable description of 
Chlidonia, based on actual specimens. His 1810 synonymy refers to Vorticella 
polypiina, L. (1767, p. 1317), an Infusorian. In 1819 he cited Esper's figures, 
thereby making his descriptions more intelligible ; while by rejecting his 
earlier synonymy he furnished a justification for the introduction, otherwise 
invalid, of a new trivial name in 1810. 
The genotype thus appears to be Chlidonia pyriformis (Bert.), of which the 
other names indicated above are synonyms. Chlidonia, Lamx., 1824, ante- 
dates both C/iZicZoma, Hiibner, 1825-1826* (Verz. bekannt. Schmetterl.p. 393) 
and Chlidonia, Herrich-Schiiffer, 1838 (in Panzer, Deutsohl. Insecten, Heft 
157), two genera of Insects. Chlidonias was introduced by Rafinesque, 1822 
(Kentucky Gazette, xxxvi. (8) p. 3), and this name is regarded as valid by 
Ornithologists. There seems to be no inconvenience in retaining Chlidonia 
for Polyzoa, in spite of its close resemblance to the name of a genus of Birds. 
Cinetoscias, von Martens, 1879, Zool. Reo. for 1877, xiv. Molluscoida, p. 94. — An 
emendation proposed b}^ von Martens, in recording the introduction of 
Kinetosldas (q. v.). Although the name might have been tlius spelt it is 
undesirable to alter the accepted original form. 
Columnaria, Levinsen, 1909, p. 116.- — Introduced for Columnaria borealis, n. sp., and 
all the species of Farciminaria described by Eusk (1884, pp. 48-51), except 
E. atlanticn. No genotype was selected, but this is of small importance, since 
the name is pre-ocoupied, in Anthozoa, by Columnaria, Goldfuss, 1826, Petr. 
German, i. pt. 1, p. 72 (for date of publication see Woodward, vol. ii. p. 692). 
L prefer not to suggest a new name without making a study of the species 
involved.
