JS^uculse, at least of such as have nearly the same form as his 

 N. margaritacea, are pearly within, the number of such is really 

 very few ; and the ligament in the Trigonise is entirely external, 

 whereas in all the Nuculse it is almost wholly internal. Besides the 

 six species mentioned by Lamarck, three are given by Montagu, three 

 by Say in his American Conchology, one in my own work on the 

 Genera of Shells, one in Wood's Suppt. and one in the Zool. Journ. 

 To these 15 I now had [.s«V] 9 from my own collection, and 10 

 collected by Mr. Cuming."

" The scientific Public and Conchologists are already aware that it 

 is intended to introduce in this work figures and descriptions of all 

 the new species which have been collected by Mr. H. Cuming. They 

 will be brought in under the various Genera to which they belong ; 

 and several have already appeared among the Cypraeadaj. I take this 

 opportunity of drawing the attention of Naturalists to this subject, in 

 tViis place, because it will be seen that half the number of species 

 of the beautiful Genus Cancellaria at present known have been 

 discovered and first brought to England by that Gentleman, to whose 

 indefatigable industry we are indebted for the knowledge of at 

 least 500 species of various Genera, among which are several new 

 Genera and a great variety of the most interesting and remarkable 

 species. The care and precision with which Mr. Cuming has 

 preserved all the particulars relative to localities and habitations of 

 the various subjects collected by him, entitle him to our warmest 

 admiration and praise, and I shall gladly avail myself of the 

 advantages afforded to me by this circumstance, not only in stating 

 the localities and habitats of such Shells as have been first discovered 

 by Mr. Cuming, but of such others as we were previously acquainted 

 with, though we know not those particulars. The descriptions of all 

 the species discovered by Mr. Cuming either have appeared or will 

 appear in the * Proceedings of the Committee of Science of the 

 Zoological Society,' to which we shall refer, by the initials Z.P. 



" The list here given of the species of the Genus Cancellaria will be 

 found to be much more copious than that in Lam. Hist. nat. des 

 Anim. sans vert, where only nine species that really belong to the 

 Genus are given,*' eight of these are in this list, and to these I have 

 added one in my work on the Genera of Recent and Fossil Shells, tw'O 

 in the catalogue of the Tankerville Collection, and sixteen in the 

 present Conchological Illustrations : the remaining twenty-one have 

 been discovered by Mr. Cuming, and are figured from his collection."
