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

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

 pubhshed his reasons for tliis 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 formarn, 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 Eev. Lansdowne 

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

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

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

 Iconica,' under the head of Mangelia, a genus proposed some years since, 

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

 find no pubhshed record. 



The Mangelia are nearest allied to those aberrant species of Pleurotoma 

 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 Marginella Tvithout 

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

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

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

 in a manner similar to that of the Pleurotomce 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 Cancellance, and the five pubhshed by Mr. 



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

 parle pas daus sa Monoyrafhie. Une telle lacune est laclieuse dans un ouvrage aussi specialement 

 consacre a I'illustratiou de la pai'tie concliyliologique des auimaux sans vertebres. M. Sowerby 

 suppose que cette coquille appai'tient a un autre genre, et si Ton s'eu rapporte a la iigure citee de 

 Martini, elle ne serait en ellet qu'un jeune Strombe. II apparteuait done a M. Kiener d'e'clairer la 

 science a ce sujet." 



And again, " M. Kiener nous laisse dans I'ignorance la plus complete a I'egard de cette espece 

 de Lamarck. Nous avons toujours cru que I'uu des buts que se proposait I'auteur du Species des 

 coquilles, etait de donner des renseignnieuts positifs sur les especes de Lamarck, miscs a sa dispo- 

 sition. En s'abstenaut, M. Kiener ote gratuitement a son ouvi-age ce qui lui aurait donne le plus 

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

 Lamarck, mais aussi a ceux des persounes qui font de la science d'une maniere serieuse et qui 

 recherchent avec avidite tout ce qui pent les eclairer sui" les especes de Lamarck. Cette Cancel- 

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

 Lamarck." — Deshayes, Animaux sans vertelires, vol. ix. p. 401 and 407.
