 to base is -il inches.

 Giraffa reticulata, Thomas, Proc. Zool. Soc. 1901, vol. ii. p. 476. 



Size rather less than in the other East African Giraffes. Dis- 

 tinguished from camelopardalis by the general colour pattern, the 

 body being reddish brown with a white network superimposed, 

 the dark body-colour thus being cut up into a number of large 

 reddish-brown rectangular patches. On the head the reticulations 

 are considerably smaller and are continued forwards over the 

 cheeks as far as the chin. Anterior horn large and very stout.
