diėre, M. Vieillot founded a new species of Goose, Anser griseus, 

 described at length in tlie second edition of the " Nouv. Dict. 

 d'Hist. Nat." Ifthis assumption be correct, the šame individual 

 mušt l)ave afterw'ards 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 vvhich Labillardiere's specimen vvas deposited. 



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

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

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

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

 racters vvhich zoologists have been in the habit of deriving from 

 the horns. The other distinctive marks are as follovvs : 



Cervus humilis, Cerv.parvus, obesus, brevipes ;Jacie latč, brevi, 

 obtusa ; Jissurd infra-orbitali mediocri ; cauda subnulla : cor- 

 pore toto riįfo, antici nigrescenti, postice Jronte pedibusęue infe- 

 rioribus saturatioribus , infra dilidiori. 



Alt. ad humeros vix 1 J ped. : long. caudae vix unciam superans. 



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

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

 England byhim ; that the young vvas spotted vvith yellovv, and had 

 a yellovv stripe on each side of the back ; and that the animal vvas 

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

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



A hybrid Pheasant belonging to the Society having lately died 

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

 a preparation of a part of vvhich, together vvith the preserved skin, 

 vvas then on the table. He remarked that in mules produced be- 

 tween animals placed at dift'erent degrees of distance from each 

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

 certain the relative statė of the sexual organs, vvhich it might be 

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

 extent of the distance interposed betvveen the parent animals. The 

 bird in question vvas a malė, bred betvveen the pheasant and the 

 commonjoijol, 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., vvere 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 vvhich united in its plumage the brovvn spotted wing of the 

 Gardcnian Heron vvith the black head and ash-coloured back of 

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

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

 but one. 



Tvvo living specimens vvere exhibited of the Suricate, Ryzana
