1868, pi. 41. 
Rhinoceros unicornis. A vertical section of a skull and a cast of the brain 
are figured by M. A. Milne-Edwards on occasion of his examination of Ste- 
reoceros. Ann. Sc. Nat. x. 1868, pis. 13 & 14. 
^ Hijraw. Dr. Gray lias reexamined the speeies of Hyrax, and 
drawn attention to eranial and dental charaeters by which divi- 
sions and species can be established which by a mere examina- 
tion of the skins can scarcely be distinguished (Ann. & Mag. 
Nat. Hist. 1868, i. pp. 35-51) *. After introductory remarks 
on the literature of this genus, he gives the following arrange- 
ment of the groups and species, each being characterized by a 
diagnosis : — 
a. Hyrax. 
a. Dorsal spot black. 
h. Dorsal spot yellow.

Rqmis cahallus. An English illustrated translation of M. Du Hiiys’s work, 
' The Percheron Horse,’ has appeared in New York, 1868, 12mo. 
^Rquus cahallus. M. A. Sanson has continued his examination of the Horse 
with five lumbar vertebrae [see Zool. Record, iii. p. 35]. It belongs to the 
Arab breed, of which, however, there is also a form with six lumbar ver- 
tebrae. This character being accompanied by others, especially in the form 
of the skull, it is evident that the two forms have a diflerent origin, the one 
with five vertebrae coming from Africa, and that with six from Asia. They 
were originally two distinct species. Robin, Journ. Anat. et Phys. 1868,
