1937. The right tibia and fibula. 



Only the proximal third of the fibula is free, and projects upwards as a styliform process 

 of the tibia. 



1938. The right astragalus. 1939. The right os calcis. 



1940. The right scaphoides. 



1941. The bones of the left hind foot. The same process of the proximal end of the 

 inner metatarsal (ii) takes the place of the inner cuneiform bone, as in the 

 common Hare : a process of the scaphoid seems to represent a rudiment of 

 the missing metatarsal. 



1942. The left radius and ulna.

1943. The left humerus, longitudinally bisected. 



1944. The left femur, longitudinally bisected. 



1945. The left tibia, longitudinally bisected. It shows the complete coalescence of 

 the fibula with the tibia, along their distal halves. 



1946. The occipital segment of the skull of a Hare. 



A bristle is passed through the sinus traversing the basioccipital by which the tympanic 

 cavities intercommunicate.

1947. The parietal and frontal segments of the same skull. 



A bristle is passed through the short ecto-carotid canal, which pierces the outer and the 

 back part of each alisphenoid, and also communicates with the interior of the cranium. The 

 intercondyloid foramen is here pierced between the ento- and ecto-pterygoid processes of the 

 sphenoid.

1948. The occipital segment, with the right petrotympanic and mastoid, of a Hare. 



A bristle is passed through the ento-carotid canal, which pierces the under part of the tym-
