BKITISH PAL^OGENE BKYOZOA. 227 



Note on the Use of the Name Oemellaria. — The name OemeVaria was first invented for a genus of Bryozoa 

 by J. C. Savigny somewhere about the year 1810; it was not, however, published till 1826 [Audouin, 

 No. I, p. 242J, and then only in the Preneh form of GemeUairt ; so far as I am aware, it was first used in a 

 Latinized form in 1830 by Blainville [No. 2, p. 425], who did not himself accept it. Before the publication 

 of OemeUarm or GemeUaire the genus had been described in 1821 by Lamouroux [No. 2, p. 7], who named 

 it Loricaria. Audouin, who completed Savigny's work when the latter was disabled by ill-health, of course 

 treated " Gemellaire " as a manuscript name and accepted Loricnria. ilost subsequent authorities, however, 

 have accepted Gemellaria and date it from 1805, 180!.), or 1811. Johnston [No. 2, p. 293, footnote] seems 

 to have entertained doubts as to the accuracy of this proceeding, but accepted it on the idea that copies 

 of some work of Savigny's had been placed in the principal libraries : he obviously could get no reliable 

 information regarding it. 



Mr. Hincks accepts the genus and quotes as its author " Savigny, 1811." The only reference he gives in 

 his Bibliography [No. 2, p. 588] to Savigny is " Iconographie des Zoophytes de I'Egypte,"' from the 'Description de 

 I'Egj'pte.' Miss Jelly [No. i, p. 284] quotes the same work, and so does MacgiUivray [No. 3, p. 223], who, 

 however, adds " not seen by me.'' I regret to have been unable to find any such work ; there is none such in 

 the Natural History Museum copy of the ' Description de TEgypte,' nor is any referred to iu " A Bibliographical 

 Account and Collation of ' La Description de I'Egypte ' " (London Institution : private circulation, 1838, 8vo, 

 76 pp.). None of the ordinarj- bibliographical works of reference give any information regarding it. 

 I therefore cannot help concluding that the authorities who have quoted tlvis mysterious " Iconographie " 



really refer to Audouin's " Explication sommaire des planches do Zoophytes de I'Egypte " That the 



date of this is 1826 and not 1811 admits of no doubt : the work was only entrusted to Audouin for completion 

 in 1825, and monographs issued in 1S21 are quoted. Loricaria has therefore the prior claim to adoption, but 

 unfortunately it had been previously used among fishes. Fleming [No. i, p. 541], therefore, in 182S renamed it 

 Natamia. N. loricata he clearly regarded as the type, for the onlj' other species he associated with it 

 (N. hursaria) he made the type of a new genus, Epistomia. Lamouroux did not include this latter species 

 in his Loricaria, but in the Sertularian Dynanema [No. i, p. 79]. Fleming, it must be remembered, only 

 proposed Notamia as a change of name owing to the preoccupation of Loricaria. The name Notamia cannot 

 therefore be separated from its type species and applied to one which both Lamouroux and Fleming assigned to 

 another genus. There is therefore no option but to foUow Fleming and substitute JSotamia for Gemellaria 

 and regard the species hursaria as the type of Epislomia. 



The only alternative is to accept Blainville's name GemiceUaria [No. i, p. 425], proposed in 1830, but there 

 does not seem any sufficient reason for a departure from the ordinarj' rule of nomenclature.

 Diagnosis.^ Membraniporidse in which the opesial aperture is generally of a simple 

 form and the lamina is absent or but slightly developed. 



' It will be seen from this diagnosis that in deference to recognized opinion Amphiblestrum is accepted ; it 

 appears to be an artificial but very convenient group.
