The tail (fig. 28) is naked on the inner surface for one-third its length; color white at base, with a black terminal brush, and but faint traces of the colored line on its upper side, which is often plainly marked in this deer. Tn this individual there is no distinct vertebral stripe. The horns, which were just starting, meas- ure 30 mm. in length. Metatarsal gland (fig. 'i'.') 75 mm. in length; the tuft of hair in which it lies, 125. Specimens examined later in the season were redder, with less sooty on the chest, the color deep- ening to cinnamon rufous on the back, becoming paler on the head. neck, and limbs. Both summer and winter skins had the dark vertebral line. Near the Pacific coast, this deer has smaller ears than in the interior, near the desert: and in summer its color is redder. A herd seen near the last Monument (No. 25S) was almost as red as the range cattle feeding near them. The blackish areas found on the mule deer of the interior region of the continent are much more intense in the Pacific-coast form. The crown of the head, much of the ears, and a vertebral stripe are usu- ally very black. When the dark vertebral line is plainly marked, it is usually prolonged on the upper side of the tail (fig. 28), connecting with the black terminal brush. The tail is composed of nine short vertebrae, Odocoileus couesi having eleven much longer ones. Oilo- in 'ill us In in hni iis califomicus has the longest tail of any form of the group known from the Mexican Border. Those from the desert side of the Coast Range often lack the black line on the upper side of the tail, and their paler colora- Fig. 29. —Odocoileus hemionus californi- C"D s. M KT AT A R- SAL GLAND.
