Oswell's letter, Dr. Gray stated that Col. Steele had also brought home the horns of a 

 new species of Tragelaphus, allied to T. Euryceros and T. Angasii. He proposed to 

 name it T. Nakong. 



Dr. Crisp exhibited the skin of a horn-bill, of which the neck-feathers were covered 

 with the eggs of an apparently new species of Acavus. Dr. Crisp observed that the 

 eggs of Acari are always deposited beyond the reach of the beak in birds. Both eggs 

 and perfect insects were exhibited under the microscope, and the subject was further 

 illustrated by elaborate drawings. 



Dr. Crisp afterwards read a paper on the habits and anatomy of the wolf-fish, con- 

 taining, among other interesting information, a careful explanation of its dental sys- 

 tem, and of the intestinal canal. 



Mr. Gould exhibited and described the nest and eggs of Menura Alberti, from 

 specimens transmitted to this country by Mr. Willcox, of Sydney. The structure of 

 the nest fully corroborated the views which Mr. Gould had developed many years since 

 as to the position of Menura among the Insessorial birds, in contradistinction to those 

 of Temminck, Illiger, Swainson, and Lesson. The Menura, according to Mr. Will- 

 cox, only lays one egg, but on that point there exists some doubt. The egg of the 

 old species, Menura superba, is still unknown. 



The Secretary read a note on the capture of Delphinus Orca in South Greenland, 

 by Mr. Rehiiller, of Thorrhavn, which was communicated by Sir W. Trevelyan, to 

 whom it was addressed. It contained the description of a method of capturing these 

 animals with a net, which had proved so successful, that the number taken in West- 

 manhavn alone, since 1843 (when the net was first used), amounted to 2200, whereas 

 between 1843 and 1819, 280 only had been secured. As each animal is taken to ave- 

 rage 30 gallons of oil, this branch of industry has produced upwards of £4000 sterling 

 to the inhabitants of Westmanhavn in the last ten years. 



Tuesday, March 22, 1853. 



Mr. Gould exhibited to the meeting four species of Tetraogallus, including a new 

 one from the collection of the Hon. East India Company, obtained in Ladak, which 

 differs essentially from the older species by its smaller size, its orange legs, and its 

 sides being streaked with black instead of tender chesnut. The name proposed for it 

 is T. Thibetanus. The whole of the species live in temperate or snowy regions of the 

 Himalaya and Caucasus; and the fine health in which T. Caucasicus has for several 

 months been preserved in the Society's menagerie, would indicate that the whole of 

 them might be acclimated in the Scotch and Cumberland mountains. 



Lieut. Burgess exhibited an extensive series of drawings of the eggs of Indian 

 birds, made by himself. 



Mr. G. R. Gray communicated the descriptions of two new species of Ptilonopus 

 in the national collection, the habitat of which is unknown. These extremely beauti- 

 ful birds were characterized under the names of Pt. chrysogaster and Pt. purpureo- 

 ciuctus. 



Mr. Westwood directed the attention of the meeting to a series of most interesting 

 drawings illustrative of the transformations of several genera of Australian insects, 

 from the able pencil of Miss Scott, of Hunter's Island, New South Wales. 



Mr. Cuming communicated a paper on twenty-three new species of land shells
