Siredon maculatum. The extensor tendon arose from the fi'ont of 

 the femur, and the ligament existed beliind it as a lamina of synovial 

 membrane. 



Rana mugiens. The synovial membrane was separate from the 

 rectus tendon, so that on cutting the latter across and thi'owing it down 

 the joint was unopened. On opening the joint the ligament was seen 

 beneath the tendon that traverses the joint, and was connected with 

 the semilunar cartilage.
