form, in the Cartilaginous Fishes, true conglomerate glands. To the 

 class of Mammalia mammary glands are peculiar ; and it might al- 

 most have been expected a priori that in that class these organs 

 should be found in the various degrees of simplicity or complication 

 of which they are capable. Such appears to be the case; in Cetacea 

 they are simple cceca (and in this respect the glands of Monotremata 

 agree with these mammary glands); in higher forms they are con- 

 glomerate, and cannot be misunderstood. 



Mr. Owen added, with reference to the microscopic test of the 

 nature of the secretion which was proposed by M.Geoffroy, that he 

 had not been able to procure either from the glands themselves or 

 the openings of their ducts any portion of their secretions to which 

 the test could be applied ; globules-of oil alone offering themselves 

 to his observation, and these existed also in the spirit in which the 

 animals were preserved. 



September 10*. — A letter was read, addressed to Mr. Vigors by 

 B. H. Hodgson, Esq., Corr. Memb. Z. S., and dated Nepal Resi- 

 dency, February 23, 1833. It referred to the zoological specimens 

 which the writer had forwarded to Calcutta, to be thence transmit- 

 ted to England, some account of which, as contained in a letter 

 from Mr. Prinsep, was read at the last Meeting. 



The Secretary called the attention of the Society to several re- 

 cent acquisitions to the Menagerie; including a specimen of the 

 red-handed Tamarin Monkey, Midas rufimanus, Geoff., presented by 

 J. Christopher, Esq. ; of the crested Porcupine, Hystrix cristata, Linn., 

 which had recently been brought forth there, being the first instance 

 of such an occurrence in this species, and respecting which he added, 

 that observation of the young while sucking confirmed the correct- 

 ness of M. Blumenbach's statement that the nipple is nearly axil- 

 lary ; of the purple-crested Touraco, Corythaix porphyreolopha, Vig., 

 presented by J.J.Audubon, Esq.; and of the Platycercus Novce 

 Hollandice, Vig., Psittacus Novce Hollandice, Lath., a species which 

 appears not to have been seen since the time when it was originally 

 described until very recently, when a living specimen for the Me« 

 nagerie, and skins for the Museum, were obtained nearly simulta- 

 neously. 



Mr. Bennett also called the attention of the Meeting to a living 

 Lemur, forming part of the Society's collection, iind pointed out the 

 distinguishing marks which induced him to consider it as the repre- 

 sentative of an undescribed species, for which he proposed the name 

 of Lemur rujifrons. 



At the request of the Chairman, Mr. Gould exhibited a series of 

 specimens of the genus Malurus, Vieill., including the whole of the 

 species previously known, together with one, forming part of the 

 Society's collection, which he regarded as hitherto undescribed. 

 He characterized it as the Mall n us pectoralis. 



Mr, Gould also exhibited specimens of the male and female of 

 the Trogon pavoniuus, Spins : the latter, he stated, has hitherto 



• The Proceeding! of August 13 and 27 will be found in the Lond. and 

 Edinb. Phil. Mag. for November last.
