818 THE ZOOLOGIST. 
C. cristatus.— One shot near Hungerford, Feb. 1808. 
C. auritus.— Frequent in all our rivers. Sometimes seen about 
Hamstead, making its nest of rushes floating on the water, and 
laying generally eight eggs of a [? dull or dirty] white. 
C. urinator.*—One shot at Sulhampstead and one at Sunning, 
Dec. 1795. 
Podiceps rubricollis (Ind. Orn. ii. 783-6).—Shot at Burghfield, 
May, 1792. 
Larus tridactylus.—In stormy springs occasionally shot. 
L. canus.—Frequent about Newbury in the spring. 
L. nevius.t—T wo shot at Reading, March, 1794. One, winged, 
lived many weeks with ducks and fowls in a large yard in the 
strictest friendship. 
L. ridibundus.—Often shot about the Kennet. 
Sterna hirundo.—Sometimes seen about Reading. 
S. minuta.—Shot at Wallingford, Sept. 1794. 
S. fissipes.—Shot at Maiden Early, Sept. 1794. 
Ardea cinerea. —Common in the marshes about Newbury. In 
a male I dissected, Dec. 1793, I found six small perch, weighing 
about 2 oz. each. 
A. stellaris.—These birds, like the above, were about thirty 
years ago very common in the marshes between Newbury and 
Reading, but since the peat has been so much dug out they are 
become very rare. From repeated dissections I found the male 
alone had the loose membrane on the internal side of the trachea, 
joined by a strong ligament, which, passing into the lungs, authors 
conclude can be filled with air and exploded at pleasure, occa- 
sioning the bellowing noise, thereby controverting vulgar errors, 
particularly of our own poet, Thompson. In all of them which 
I have dissected I have found the female alone possessing the 
singular formation of the trachea, which after having passed into 
the thorax to the lower part of the sternum, was reflected to the 
superior portion of that bone, was again reflected, divided, and 
passed into the lungs. Some of the above observations were 
transmitted to my inestimable ornithological friend, Dr. Latham, 
F.L.S., and noticed by him in the second Supplement of his 
‘ Synopsis.’ 
* Podiceps cristatus in the winter plumage. Itis singular that the author should 
have placed some of the Grebes in the genus Colymbus, but the Red-necked Grebe in 
the genus Podiceps.—Ep.
