[A cock and two hens of Prince Albert's Curassow, Crax albertl.'] 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.-Right 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. II.-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. III.-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 III. belong to one nest, but II. belongs to a later nest. Mr. Doggett states that be had seen one or both birds wdth more or less webbing in four different pairs of young reared by the same parents. Figures showing the right foot of III. and the left |
