registering the observations; or if both the sidereal and mean time 

 were given, as in the Greenwich Observations. 



" Should this subject be found to possess sufficient interest to 

 engage a few careful observers in thus watching for the eclipses of 

 Jupiter's satellites during the present year, the results might be 

 communicated to the Society, so as to appear in one of their 

 Monthly Notices during the session of 1834- ; and thus evidence 

 would be had, at one view, of the degree of advantage to be ex- 

 pected from the adoption of such a plan of simultaneous and uni- 

 form observation." 



ZOOLOGICAL SOCIETY. 



June 11. — A specimen of the Patagonian Penguin, Aptenodytes 

 Patachonica, Gmel., recently presented to the Society by Lady 

 Rolle, was exhibited. Mr. Yarrell availed himself of the oppor- 

 tunity to point out on it the proofs which it afforded of the state- 

 ment made by him at the Meeting on March 12, that the woolly 

 Penguin of Dr. Latham is the young condition of this species. 



A specimen was exhibited of a Goose from the Sandwich Islands, 

 being one of a pair recently living at the Society's Gardens, to which 

 they were presented by Lady Giengall. Mr. Vigors characterized 

 it as a species of Barnacle Goose, by the name of Bernicla Sandvi- 

 censis, and pointed out its distinguishing marks. He also observed 

 on the general resemblance in the distribution of colouring which 

 occurs in the species of Bernicla and in those of many other groups 

 of Birds. 



Numerous skins of Birds were exhibited, which had recently been 

 obtained by the Society from California. They formed part of the 

 collection, the Mammalia of which were brought under the notice of 

 the Society by Mr. Bennett on March 26 (see page 66). Mr. Vi- 

 gors remarked on them generally as regarded the geographical distri- 

 bution of many of them; and pointed out, as apparently hitherto un- 

 described, an Ortyx, a Falco, two species of Coccothraustes , and a 

 Psittacara. Among the known birds were several of those first 

 described by Mr. Swainson in the i Fauna Boreali- Americana,' and 

 a specimen of Ortyx Montezumce, Vig. 



Dr. Grant directed the attention of the Meeting to a fine entire 

 skull of the round-headed Grampus, (Delphinus globiceps, Cuv.,) 

 from the North Pacific Ocean, presented to the Society by Capt. 

 Delvitte, R.N., Corr. Memb. Z.S. He availed himself of the op- 

 portunity of entering into some details regarding the osteology 

 of the head of the Grampus and other predaceous Cetacea. 



Specimens were exhibited of two Monkeys, forming part of the 

 Society's Museum, which Mr. Bennett characterized as Semnopi- 

 thecus Nestor and Cercopithecus pogonias. The former may be 

 assumed to be a native of India; the latter is from the vicinity of 

 Fernando Po. 



A specimen was exhibited of the black Lemur, Lemur niger, 

 Geoff., which had recently been added to the Society's Menagerie. 

 In calling the attention of the Society to it, Mr. Bennett stated his
