4. Zoological Society, (11, Hanover Square.) 



March Uth, 1865. 



The Secretary called the attention of the meeting to several recent 

 interesting additions to the Society's Menagerie, amongst which were 

 specimens of a three-banded Armadillo (Toli/peutes conurus) and a 

 male Siamese Pheasant {JEuplocamus prcelatus) . — Mr. Alfred Newton 

 exhibited specimens of several new or little-known Birds' Eggs, and 

 gave descriptions of others, amongst which were those of Elanoides 

 furcatus, Nucifraga caryocatactes^Didunculus strigirostris, JPhalaropus 

 fulicariuSj Opistliocomus cristatics, Mareca americana, and Fulix affinis. 

 Mr. Newton believed that the eggs of the Nutcracker {Nucifraga 

 caryocatactes)^ which had been obtained from the island of Bornholm, 

 were the first really authentic examples of this species that had 

 reached this country. — Mr. Sclater exhibited and made remarks on 

 the eggs of several birds, laid in the Society's Menagerie, amongst 

 which were those of the Horned Pheasant Ceriornis satyra). — A paper 

 was read by Mr. W. S. Dallas, on the feathers of Dinornis rohustus, 

 in which a full description of their structure, as exhibited in a por- 

 tion of the skin of this extinct bird attached to a skeleton, lately 

 acquired by the Yorkshire Philosophical Society, was given. The 

 remnants of the large accessary plume attached to each feather, 

 manifested a near relationship between Dinornis and the Emeus and 

 Cassowaries. — Dr. Crisp read a paper on the Anatomy of the Bactrian 

 Camel, in which a description of certain intestinal glands, not before 

 noticed in this animal, was given. — Dr. J. E. G-ray gave a notice of 

 a Common Porpoise {Fhoccena communis), which had lately died in 

 the Society's Gardens, and which was remarkable for having a row of 

 tubercles on the upper margin of the dorsal fin. This structure did 

 not appear to have been previously noticed in the Common Porpoise, 

 although a species from South America, lately described by Dr. Bur- 

 meister, possessed it in a highly developed degree. — Three communi- 

 cations were read from Dr. P. P. Carpenter, entitled — (1.) Descrip- 

 tions of new species or varieties of Chitonidce and AcmcBidce, from the 

 Panama collection of the late Professor C. B. Adams. (2.) Diag- 

 noses of a new species of Mollusks, from the West Tropical region of 

 North America. (3.) Diagnoses of a new species and a new genus 

 of Mollusks, from the Eeigen Mazatlan collection, with an account of
