This new species is a native of the north-west coast of America, where it was first found by Mr. Menzies in the voyage of discovery under Vancouver, and it has been very properly named in compli-ment to that venerable botanist. The plant bears a close resemblance to some species of Disporum, and it moreover agrees with that genus in its sepals being produced into a short spur or pouch at their base. The flowers are consi-derably larger than those of lanuginosa, and they are apparently of a yellow colour. The style is long and copiously hairy. The genus is essentially distinguished from Disporum by its innate anthers, nearly concrete styles, and pendulous seeds. ZOOLOGICAL SOCIETY. March 12, 1839.— William Yarrell, Esq., in the Chair. Mr. Ogilby communicated a portion of a letter which he had re-ceived from M. Temminck. It related to two species of Monkeys, Colobus fuliginosus and Papio speciosus ; the former M. Temminck considers identical with the Bay-Monkey of Pennant, and he states that this opinion is founded upon its agreement with a coloured drawing now in his possession ; this drawing having been taken by Sydenham Edwards from the specimen of the Bay-Monkey
