diere, M. Vieillot founded a new species of Goose, Ariser griseus, 

 described at length in the second edition of the " Nouv. Diet. 

 d'Hist. Nat." If this assumption be correct, the same individual 

 must have afterwards served as the type of his figure of the Cere- 

 opsis ; for only a single specimen of that bird existed until very lately 

 (or indeed probably still exists) in the gallery of the Paris Museum, 

 in which Labillardiere's specimen was deposited. 



A specimen was exhibited of a small species of Deer from Chili, 

 which had lived in the Society's Menagerie for upwards of twelve 

 months, and which Mr. Bennett stated that he believed to be new. 

 It is a female, and consequently does not offer the accessory cha- 

 racters which zoologists have been in the habit of deriving from 

 the horns. The other distinctive marks are as follows : 



Cervus humilis. Cerv. parvus, ohesus, brevipes ; facie latd, hrevi, 

 obtusa ; Jissurd injra-orbilali mediocri ; cauda siibnulla : cor- 

 pore toto riifo, aniice nigrescenti, postice fronte pedibusque infe- 

 rioribus saturatioribiis , hifra dilidiori. 



Alt. ad humeros vix IJ ped. : long, caudae vix unciam superans. 



Mr. Bennett added that he was informed by Captain P, P. King, 

 R.N., that a second skin of the same species had been brought to 

 England by him ; that the young was spotted with yellow, and had 

 a yellow stripe on each side of the back ; and that the animal was 

 plentiful at Concep9ion, and found even as far south as the Archi- 

 pelago of Chiloe, living, he believed, in small herds. 



A hybrid Pheasant belonging to the Society having lately died 

 at the Garden, Mr. Yarrell observed that he had examined its body, 

 a preparation of a part of which, together with the preserved skin, 

 was then on the table. rie remarked that in mules produced be- 

 tween animals placed at different degrees of distance from each 

 other in the scale of Nature, it was a point of some interest to as- 

 certain the relative state of the sexual organs, which it might be 

 expected would be found more or less perfect, depending on the 

 extent of the distance interposed between the parent animals. The 

 bird in question was a male, bred between the pheasant and the 

 common Jbivl, but most allied in appearance to the former. The 

 sexual organs appeared to be perfect and of large size for the pe- 

 riod of the year. 



Three examples of the Ardea Nycticorax, Linn., were placed on 

 the table. On these Mr. Yarrell observed that the Menagerie of the 

 Society had furnished an interesting link in this species, in a young 

 bird which united in its plumage the brown spotted wing of the 

 Gardenian Heron with the black head and ash-coloured back of 

 the Niglit Heron : thus exhibiting the change from the young to 

 the adult bird, and proving that the two supposed species are really 

 but one. 



Two living specimens were exhibited of the Snricate, Ryzana
