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

 in the ' Nouveaux Mėmoires de l'Acadėmie Impėriale de St. Peters- 

 bourg.' Mr. Bennett characterized it as the 



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

 genis in medio nudiuscuUs. 



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



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

 restless Cavy, Cavia Cobaya, Gmel., popularly knowii as the Guinea- 

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

 tvhich are slightly tinged with bro\vn. Its ears are rather large, 

 broadly expanded, and hair}- ; 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 \vhich 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 skuU is rather more expaiided 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 coUection 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 vėre 

 much indebted. The tri\-ial 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-westem coast of Pata- 

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

The coUection also contained specimens of a Mouse, for which 

 M r. Bennett proposed the name of 



Mus Magellanictjs. Mus caudd corpus caputque longitudine aguan- 

 te ; suprcL saturate suhflavicanti-fuscus ; subtiis albidus ; pedibus 

 albis. 



Long. corporis cum capite 4i ; caudtE 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 foUowing remarks. 



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

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

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

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

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

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

 scribed species of Phalanger, which I propose to call 



Phalangista Canina. lt is similar in size and general proportions
