including the two which have recently been described by M. Brandt 

 in the ' Nouveaux Memoires de I'Acad^mie Imp^riale de St. Peters- 

 bourg.' Mr. Bennett characterized it as the 



Cavia Cutleri, King MSS. Cav. hrunnescenti-nigra ; subcristata ; 

 gents in medio nudiusculis. 



Long. tot. 10 unc. ; capitis, 3. 



The general form of the animal is probably similar to that of the 

 restless Cavy, Cavia Cobaj/a, Gmel., popularly known as the Guinea- 

 pig. It is covered universally by long, smooth, glossy, black hairs, 

 which are slightly tinged with brown. Its ears are rather large, 

 broadly expanded, and hairy ; and between them the hairs are longer 

 than those on the adjoining parts, occasioning a slight appearance of 

 a crest. On the middle of each cheek the hairs radiate as from a 

 centre, almost in a similar manner to that in which they spread from 

 around the crown of the bonneted Monkeys, and the skin is conse- 

 quently left in the middle point almost bare. The dentition is alto- 

 gether that of the restless Cavy, and the incisors, as in it, are white. 

 The skull is rather more expanded laterally, which gives to it an 

 appearance of comparative flatness. 



"This animal was known, on the survey, by the name of the Pe- 

 ruvian Cavy. The specimen in the Society's collection was presented 

 to one of the officers of the Beagle by an American sailing-master, 

 of Stonington, U.S., a very intelligent person, to whom we were 

 much indebted. The trivial name which I have proposed for it is in 

 recollection of the benefit we derived from his experience and know- 

 ledge of the intricate navigation of the south-western coast of Pata- 

 gonia, which was freely imparted to us on several occasions." —

The collection also contained specimens of a Mouse, for which 

 Mr. Bennett proposed the name of 



Mus Magellanicus. Mus caudd corpus caputque longitudine aquan- 

 te ; suprcL saturate subflavicanti-fuscus ; subtus albidus ; pedibus 

 albis. 



Long, corporis cum capite 4i ; caudeE longitudo eadem ; pedis pos- 

 tici, 1. 



Hab. apud Portum Famine dictum, in Fretu Magellanico. 



The ears are of moderate size, rounded, and hairy. 



Specimens were exhibited of several Marsupialia, on which Mr. 

 Ogilby made the following remarks. 



"A small collection of Marsupial Quadrupeds, which Mr. Gould 

 lately received from his brother-in-law, Mr. Coxen, contains two or 

 three interesting species, wliich the usual kindness of Mr. Gould 

 enables me to notice. They were all procured, as I am informed, in 

 the country beyond the Hunter River, about eighty miles north of 

 Sydney in New South Wales. The most remarkable is an unde- 

 scribed species of Phalanger, which I propose to call 



Phalangista Canina. It is similar in size and general proportions
