We feel happy, that in recording this new and beautiful bird, an early opportunity is given us of commemorating our deep sense of the kindness we received from a young naturalist of France, whose writings have already acquired celebrity, and who promises to inherit the great and commanding talents of his illustrious father. In prosecuting our studies at the _Garden of Plants_, we met with such unexampled liberality from its most distinguished Professors, that we feel embarrassed where first to return our thanks. But the facilities and attentions we received from M. Isidore Geoffroy Saint Hilaire, partly involved a sacrifice of personal convenience; uncalled for, either by the nature of his appointment, or by the common rules of courtesy. So much for the reception which British naturalists receive in France. We should do well, when striving to imitate the Zoological Institutions of that nation, if we imbibed somewhat more of their liberality. We hope the time is not far distant, when the system of regulations and restrictions, which now fence the Museum of a popular Society, from all who cannot pay for admittance, as members, may be exchanged for a policy more creditable to the age, and more honourable to the nation. We shall offer a few remarks, illustrating this particular genus, in our next number. Total length, 9 in.; wings 5; tail (beyond) 1½, from the base, 3½. * * * * * * [Illustration: AMPULLARIA Pl. 1. _A. carinata._] AMPULLARIA carinata. _Carinated Apple-snail._ ---- Family Ampullaridæ.--Guild. GENERIC CHARACTER. PACHYSTOMA. Shell ventricose; margin of the lip thick, generally grooved; operculum testaceous. Zool. Journ. 12. p. 536. SPECIFIC CHARACTER. _Shell olive, ventricose, without bands; whorls carinated near the suture._ ---- In the first Series of our Illustrations, we endeavoured to lessen the confusion which, at that time, prevailed among the species of Ampullaria, figuring and naming such as appeared to us truly distinct. During the course of our labours, the sixth part of the "_Animaux sans Vetebres_" of the celebrated Lamarck was published in Paris; in which is described several species, figured in our volumes under other names. A want of mutual communication between authors writing at the same time, and on the same subject, has naturally caused confusion in nomenclature; which, at an early period, we intend to elucidate. Our friend the Rev. L. Guilding, whose accuracy of observation can only be equalled by his indefatigable zeal, has established the distinction between the horny and shelly operculated _Ampullariæ_, on anatomical principles. The present species (which was engraved before his valuable memoir was published) must consequently be placed in his genus _Pachystoma_; while the _carinata_ of Lamarck, from having a horny operculum, remains with the true Ampullariæ.
