•authority " mon cabinet " attached to that species in the ' Animaux sans 

 vertebres/ * It would certainly have been desirable if M. Kiener had 

 published his reasons for this omission, for they were probably founded on 

 the discovery that the shell in question is not only no Cancellaria at all, 

 but that it is not referable to any genus hitherto established. Mr. 

 Sowerby had already intimated that this shell belongs to another genus ; 

 and M. Deshayes erroneously thinks, from Martini's figure, that it may 

 be the young of Strombus plicatus. 



This " Fusus ad formam cithara compositus " of Martini, Cancellaria 

 citharella of Lamarck, has been collected in various states by Mr. Cuming, 

 at the Philippine Islands, together with upwards of fifty other closely allied 

 species, the whole of which are new, and display a very striking association 

 of character. In addition to these I have a new one from Australia, one 

 from Sicily, some from the West Indies, collected by the Rev. Lansdowne 

 Guilding, and five collected by Sir. E. Belcher, during the surveying expe- 

 dition of the ' Sulphur/ described and figured by Mr. Hinds in the Zoology 

 of that voyage; all of which have been published in the 'Conchologia 

 Iconica/ under the head of MangeUa, a genus proposed some years since, 

 in manuscript, by the late Dr. Leach of the British Museum, of which I 

 find no published record. 



The MangeUa are nearest allied to those aberrant species of Plenrotoma 

 in which the predominant character of that genus, the fissure in the upper 

 extremity of the lip, becomes modified into a somewhat obscure sinus. 

 Their general aspect is that of a more or less fusiform MargineUa without 

 plaits or polished exterior ; distinguished, on the other hand, by a row of 

 faint wrinkle-like denticulations on the inner surface of the lip and colu- 

 mella, and a gutter-like sinus in the lip, at its junction with the body- whorl, 

 in a manner similar to that of the Plenrotoma above referred to. 



It is rarely an author has the pleasure of introducing a whole genus of 

 seventy new species, but such is the opportunity which the indefatigable 

 exertions of Mr. Cuming have afforded me, with the exception of the one 

 included by Lamarck with the Cancellaria, and the five published by Mr. 



* " II y a line autre coquille, la Cancellaria citharella de Lamarck, et dont M. Kiener ne 

 parle pas dans sa Monographie. Une telle lacune est i'aebeuse dans un ouvrage aussi specialement 

 consacre a l'illustration de la partie coucliyliologique des animaux sans vertebres. M. Sowerby 

 suppose que cette coquille appartient a un autre genre, et si Ton s'eu rapporte a la figure cite'e de 

 Martini, elle ne serait en eii'etqu'un jeune Strombe. II appartenait done a M. Kiener d'eclairer la 

 science a ce sujet." 



And again, "M. Kiener nous laisse dans l'ignorance la plus complete a 1'e'gard de cette espece 

 de Lamarck. Nous avons toujours ciu que l'un des buts que se proposait l'auteur du Species des 

 coquilles, etait de donner des renseigmncuts positifs sur les especes de Lamarck, mises a sa dispo- 

 sition. En s'abstenaut, M. Kiener ote gratuiteinent a son ouvrage ce qui lui aurait donne le plus 

 d'interet, non-seulement aux yeux des simples amateurs, qui tous consultant les travaux de 

 Lamarck, mais aussi a ccux des personnes qui font de bi science d'une maniere serieuse et qui 

 recbercbent avec avidite tout ce qui pout les eclairer sur les especes de Lamarck. Cette Cancel- 

 laria citharella, d'apres la figure de Martini, nous semble une jeune Strombus plicatus de 

 Lamarck." — Deshayes, Animaux mux vertebres, vol. ix. p. 401 and 407.
