226 Zoological Society. 



It was observed that young of the same species had been born at 

 the Society's Gardens, but not living ; and that a female in the 

 collection of the President, the Earl of Derby, at Knowsley, had pro- 

 duced, about the same time as Lady Rolle's, two living and healthy 

 young ones, which are still thriving. 



Mr. Gould exhibited a living specimen of the red-billed Toucan, 

 Ramphastos erythrorhynchus, Gmel., which had recently come into 

 his possession. 



The exhibition was resumed of the new species of Shells contained 

 in the collection of Mr. Cuming. Those brought at the present Meet- 

 ing under the notice of the Society were accompanied by characters 

 by Mr. G. B. Sowerby, which are given in the ' Proceedings'. 



Genus Venus. Ven. Columbiensis, subimbricata, undatella, discre- 

 pans,multicostata {long. 4*3, lat. 2' 7, alt, 3*7 poll. — perhaps thelargest 

 species known), Peruviana, Australis, and spurca. 



Genus Cytherea. Cyth. radiata (belongs to that division of the 

 genus which has four cardinal teeth, and is destitute of the cordiform 

 anterior impression), unicolor, concinna, and squalida (bears some re- 

 semblance to Cyth. maculosa). 



March 10. — Specimens were exhibited of several species of Tro- 



fon, partly from the Society's collection, and partly from that of 

 Ir. Gould; and, at the request of the Chairman, Mr. Gould called 

 the attention of the Meeting to some of the more interesting among 

 them. 



One of them was the Bird represented by M. Temminck, in his 

 * Planches Coloriees ', under the name of frog, fasciatus ; and on this 

 Mr. Gould remarked, that having had an opportunity of examining 

 the drawing made by Forster, on which Pennant's original descrip- 

 tion was founded, he had ascertained that it represented a species 

 altogether distinct from M. Temminck's Z?iu£, and much more nearly 

 resembling Trog. Malabaricus. As the name of Trog. fasciatus 

 must necessarily remain with the species originally described under 

 it, the one figured by M. Temminck requires another designation; 

 and Mr. Gould proposed for it that of Trog. Temminckii. 



Another, was the splendid species figured by M. Temminck, in 

 the same work, under the name of Trog. pavoninus, a name by which 

 it is now generally known; but on referring to M. Spix's 'Avium 

 Brasiliensium Species Novae', the original description and fgure of 

 Trog. pavoninus, Spix, appear to Mr. Gould to have reference to a 

 totally different species, distinguishable by its smaller size, by the 

 absence of crest from its head, by the comparative shortness of its 

 hinder back plumes (which do not extend more than a few inches 

 beyond the tail), and by the whole of the tail-feathers being black. 

 The species exhibiting the peculiarities just adverted to will, of 

 course, retain its original name of Trog. pavoninus ; for the other 

 Mr. Gould proposed that of Trogon resplendens. 



Mr. Gould also characterized two species, hitherto apparently un- 

 described, as Trog. ambiguus and Trog. citreolus. 



March 24. — A Letter was read, addressed to the Secretary by 

 W. Wiltshire, Esq., Corr. Memb. Z.S., dated Mogadore, February 9,
