Mr. W. Bat«son exhibited three common blue A ntwerp Pigeons, 

 lent by Mr. V. Doggott, of Cambridge, sliowiug 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. — Ric/Jitfoot. 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. — Bight 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 tliree digits completely webbed together 

 to tlie bases of the claws. Eight 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 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 III. and the left
