Mr. W. Bateson exhibited three common blue Antwerp Pigeons, 
lent by Mr. F. Doggett, of Cambridge, showing webbing between 
the toes. The amount of webbing differed in each case. All the 
birds were the offspring of a single pair which were absolutely 
normal. The following remarks gave the details of each case :— 
I.— hight foot. Digits 2 and 3 united by a web extending nearly 
to end of 2nd phalanx of each toe. In digits 3 and 4 the web does 
not extend quite so far. 
Left foot. Like right foot, but the edge of the web between 
digits 2 and 3, when the foot is extended, stretches more nearly in 
a straight line from digit to digit, instead of being curved to form 
a bay. 
Il.—Right foot. Digits 3 and 4 webbed like 2 and 3 in right 
foot of foregoing. Digits 2 and 3 not webbed at all. 
Left foot. Like the right, but the web between digits 3 and 4 
extends rather beyond 2nd phalanx and is continued up the 
side of the toes on to the terminal phalanx as a narrow flap of 
skin. 
II1.—Both feet have the three digits completely webbed together 
to the bases of the claws. Right foot has digits 3 and 4 united by 
a loose web, but digits 2 and 3 are closely webbed together, so 
that they can scarcely be moved independently. In the left foot 
all three digits are thus closely united and the foot has a somewhat 
deformed appearance. The bird can, however, sit on a perch 
without difficulty. 
The hallux is normal in every case. 
The web is pink, healthy-looking skin, with scaling on the dorsal 
surface near the digits. - 
The birds I. and ITI. belong to one nest, but IT. belongs to a later 
nest. Mr. Doggett states that he had seen one or both birds with 
more or less webbing in four different pairs of young reared by the 
same parents. Figures showing the right foot of ILI. and the left
