SI 2" Address delivered at the sixth and last 



still continues to afford us many striking novelties. Two spe- 

 cies of the family of Tetraonidae, belonging to the singular 

 group of Cryptonyx, in which the nail of the hinder toe is 

 wanting, have been lately exhibited in this room, and subse- 

 quently described in the Zoological Journal under the names 

 of Crypt, niger and ferrugineus. Some other Gallinaceous 

 species, together with a few Raptorial and Insessorial birds, 

 still remain to be characterised from that collection. This 

 pleasing task is now in progress ; and a detailed catalogue of 

 the whole of the collection, which is no less interesting from 

 the materials of which it is composed, than from the circum- 

 stances under which it was formed, is in the hands of the offi- 

 cers and other confidential members of the Society where it 

 is deposited. I have also to notice the arrival of some birds 

 from Dr. Heineken of Madeira, which had been previously 

 described by that gentleman in Dr. Brewster's Edinburgh Jmir^ 

 not. The specimens were accompanied by some additional ob- 

 servations, which will shortly appear in the Zoological Journal^ 

 and which, with the previous descriptions, will tend to clear 

 up many doubtful points respecting the birds of Madeira. In 

 particular, we have an opportunity of ascertaining, from these 

 specimens, what was the true jPringilla canaria of Linnaeus. 

 Some living specimens of that species, from which all our nume- 

 rous domesticated varieties have proceeded, are to be seen, with 

 their true and native characters, in the aviaries of the Zoolo- 

 gical Society. To Dr. Bancroft, also, of Jamaica, a valuable 

 corresponding member of the same Society, we are indebted 

 for some subjects of ornithology from the island where he 

 resides, which will shortly be given to the public. 



One of the most prominent objects in the institution of our 

 parent Society was the elucidation of the British Fauna. 

 This, of course, has been an equally important object with 

 ourselves ; and how far we have contributed to this end, may 

 be inferred from the fact that, in the department of birds 

 ialone, above twenty species * have been added to our catalogue 



* It may not be uninteresting to mention the names of the species thus 

 added to our Fauna. They are as follows : — jStrix Tengmalmi Linn., 

 Sylvia suecica Lath.^ Sylvia Tithys »S'cop., ^'nthus Richardi VieilL, Accentor 

 alpinus Bechst., Emberiza hortulana Linn.y Plectrophanes lapponica Meyer^ 

 Loxia Pytiopslttaca Bechst.y (Scolopax Sabini V., Trlnga rufescens Vieill.y 

 Tringa Temmlnckij Leisler, Gallinula Baillonii VieilL, Cygnus Bewickw 

 Yarr., " J'nser gambensis Briss.y ^^nas rufina Pall.y ^'nas casarka Linn., 

 Sterna arctica Temni., iarus glaucus Brunn.^ iarus eburneus Linn., Lestris 

 pomarinus Temm. To these species, entirely new to Britain, may be added 

 two more, which had previously been indicated as British, but not sufficiently 

 authenticated until lately ; viz. Chatadrius cantianus Lath., ^'nas glocitans 

 Pall.
