Cervus ITiictttanensiiii. 



This beautiful deer is found throughout Yucatan and the

 legs a brownish-yellow, lighter on the inner side ; the inner 

 side of the thigh, and the under side of the tail, as well as

 each side of the nose and upper lip ; a black line reaches 

 from the nostril to the edge of the lip, and also passes 

 around the lower jaw.

 and there is no gland on the metatarsal bones.
