212 Address delivered at the sixth and last 
still continues to afford us many striking novelties. ‘Two spe- 
cies of the family of Tetradnidse, 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 Crfpt. 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 cireum- 
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 Jour- 
nal. The specimens were accompanied by some additional ob- 
servations, which will shortly appear in the Seological 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 /ringilla canaria of Linneeus. 
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 TFauna. 
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: 
alone, 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: — Strix Tengmalm: Linn., 
S§lvia suécica Lath., Sylvia Tithys Scop., A’nthus Richardé Vieill., Accéntor 
alpinus Bechst., Emberiza hortuiana Linv., Plectrophanes lapponica Meyer, 
Loxia Pytiopsittaca Bechst., Scdlopax Sabini V., Tringa rutéscens Vieill., 
Tringa Temminckii Leisler, Gallinula Bailloné Vieill., Cygnus Bewickia- 
Yarr., A’nser gambénsis Briss, A‘nas rufina Pall., Anas casarka Linn,, . 
Stéma arctica Zemm., Larus glaicus Brunn., Larus ebirneus Linn., Leéstris 
pomarinus Zenm. 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. Charadrius cantianus Lath., Anas glocitans ’ 
Pall.
