Hindergliedmassen. Morph. JB. xiv, pp. 223-328, pis. xi & xii. 
A very elaborate memoir on the structure and development of the 
distal portion of the hind limbs of Mammals, especial attention being 
directed to the mutual relations of the astragalus and calcaueum.

A careful description of the foetal organ of Rosenmuller, or epoophoron, 
as displayed in the Sheep. New terms are proposed for the canals found 
in this structure.

Turner, W. Comparison of the Convolutions of the Seals and Walrus 
with those of the Carnivora and of Apes and Man. »J. Anat. Phys. 
xxii, pp. 554-581. 
After comparing the cerebral convolutions in these groups, it is con- 
cluded that the smooth-brained lower Primates could not have been 
derived from the Carnivora , or at least from Carnivora which had 
acquired convoluted brains, since such convolutions would be unlikely to 
disappear. If the higher Primates have been derived from lower Primates , 
then the hemispheres of the former, with their complex convolutions, 
have been evolved from a smooth- brained stock, and not from an animal 
with a brain like that of a Dog or Seal. Accepting this, it is not sur- 
prising to find that the mode of arrangement of the convolutions in the 
Primates differs from that obtaining in the Carnivora.

Describes several Mammalian remains from the Middle Miocene of 
Eibiswald, but more especially a skull referred to Rhinoceros sansaniensis . 
This skull appears to have had but a single horn, and therefore indicates 
the distinctness of R. sansaniensis from the Lower Pliocene R. schleier- 
macherij with which it has generally been identified,
