A CASE OF A SYNDACTYLOUS CAT

epiphysis, a proximal and a medial phalanx. Each of the proxi- 

 mal and medial phalanges shows a distinct proximal epiphysis.. 

 The distal phalanx representing digit 3-4 and the distal phalanx 

 of digit 5 have fused in a curious way. The bone thus formed 

 articulates with the distal end of medial phalanx 3-4 and with 

 the side of medial phalanx 5. The claw borne by this distal 

 phalanx shows the parts of two claws quite distinctly (fig. 2).

The metatarsal bones of digit 3-4 are relatively short. As a 

 result the distal end of the medial phalanx is approximately 

 even with the distal end of the proximal phalanx of digit 5. 

 This discrepancy in length accounts for the peculiar articulation 

 of the distal phalanx. The fusion of these distal phalanges has. 

 resulted in a bending inward of the phalanges of digit 5 (fig. 5).
