All of which numerous divisions were successively descanted on, 
more particularly as regards their anatomical characters of agreement 
and difference. 
The Cantores were more summarily disposed of ; the author 
expressing an intention to treat on the sub-division of this orderin a 
special memoir. It differs remarkably from the preceding group of 
Strepitores, in being as difficult to sub-divide as that order was to 
bring together in large groups ; for, though containing, perhaps, 
triple the number of species, at the lowest rough estimate, the re- 
semblance, in all the essential details of structure, was stated to be 
so exceedingly close throughout, that divisions of analogous value to 
those distinguished by names bearing the termination rostris could 
scarcely be instituted. After describing severa] constant and inva- 
riable characters peculiar to this strongly-marked, vast order, and 
offering a few general concluding remarks, postponed the considera- 
tion of the remaining portion of his Systema Avium for a future oc- 
casion. 
A discussion ensued, in which satisfaction was expressed that the 
internal conformation of birds, which had hitherto been much neg- 
lected by the generality of systematists, had, in this instance, re- 
ceived its due share of investigation. 
Jury 10th.—A fine mounted specimen of the Burrhal Sheep was 
exhibited, the skin of which had been forwarded to the Society by 
J. E. Bicheno, Esq. This animal was killed at an altitude of 1700 
feet on the Himmalayas, near the Berinda Pass, communicating with 
Chinese Tartary: it is a species of most excessively wary disposition, 
so much so, that, in the notice accompanying the specimen, it was 
stated that no previous example of it had been obtained by Euro- 
peans ; and the individual sent was killed by a rifle bullet at a dis- 
tance of 300 yards. Mr. Ogilby, however, observed that a speci- 
men, unique until that time, existed in the museum of the Linnean 
Society ; and stated his conviction that another species of Muffon, 
with enormous horns, inhabited the same colossal range of moun-
