238 Miscellaneous. N. bifrons by the same process. This last gemmation has been ob-served by the author in all its phases. He saw two specimens of N. splendidtti enveloped in a sort of mucosity, open and evacuate the whole of their contents, which served to form a N. hifrons. The production of the reproductive bodies by the latter was also observed ; but their development into Surirella microcora and the production oi N. splendida by conjugation rests entirely on the inductions of the author. These facts require revision and confirmation, but they are still worthy of the attention of observers, and appear to point to phsenomena quite as singular as those which have been revealed to us within the last few years by the study of the reproduction of so many of the lower animals. They in fact present in a manner the converse of the pheenomena exhibited in the ordinary alternation of generations, as several germs or eggs are necessary for the production of the last individual of the cycle. — Comptes Bendus, Jan. 22, 1855, p. 167. On Lottia zebrina and L. Scurra. By Dr. J. E. Gray. In the Philosophical Transactions for 1833, I referred these com-mon Peruvian Mollusca to the genus Lottia^ If I recollect rightly/ ;^ ( M. D'O rbigny, in his * Voya ge to South^ 4sag^^(£p"^^~^^ exami-/ nation oFsome animals of these shells in Paris/j5gures these animals, and refers them to the genus Patella ; and putting faith in the accuracy of this determination^in the Catalogue of M. D'Orbigny's collection, which has lately been transferred to the British Museum, I observed, " These are Patellce, and not Lottice.** In the Mollusca collected by M. Souleyet during the voyage of the ' Bonite,* which have lately been acquired by the Museum, there are several speci-mens of this shell, belonging to two of the varieties of it which M. D'Orbigny has regarded as distinct species, and, on examination of the animals, they prove to be Lotties, and not Patellce ; — peculiar, like Lottia Scurra, for having a series of rather large beards round the inner edge of the mantle ; and I suppose M. D'Orbigny must have mistaken these beards for the gills, and thus made the mistake which I am now desirous of rectifying. The gill of Lottia zebrina, and of several other species without or with only very rudimentary beards on the mantle-edge, as L. 'punctata, is free and floating in the nuchal mantle-cavity for the greater part of its length, while the gill of L, Scurra, the type of the proposed genus Scurria, is attached by its outer or left edge to the inner surface of the mantle, which induced me, with its peculiar habits, to regard it as a genus distinct from Lottia.
