or lachrymal vacuity of such dimensions as to exclude the lachrymal 

 bone from articulation with the nasal. Upper canines usually pres- 

 ent in both sexes, and sometimes attaining a very great size in the 

 male. Lateral digits of both fore and bind feet almost always 

 present, and frequently the distal ends of the metapodials. Placenta 

 with few cotyledons. Gall bladder absent (except in Moschus).

Subfamily CERVIN^E. 



Horn- deciduous, .solid, developed from the frontal bone, more or 

 less branched, covered at first by a soft, hairy integument, known as 

 "velvet;" when the horns attain their full size, which they do in 

 a very short time, there arises at the base of each a ring of tubercles, 

 known as the "burr;" this compresses and finally illiterates the 

 blood vessels supplying the velvet, which dries up and is stripped 

 off, leaving the bone hard and insensible; the horns or " antlers " are 

 sheil annually, the separation of the " beam " from its " pedicel " tak- 

 ing place just below the burr; antlers are [normally] wanting in the 

 female (excepting in the reindeer), but they are presenl in tin' male 

 of nearly all species. Stomach in four divisions, of tin' ordinary 

 ruminant pattern. Dental formula, i. j^; c. (usually) j^; jnn. :J :*.

 under the Government of the United Slates, and others were purchased in 

 18G6. These were distributed through Arizona and Texas for breeding pur- 

 poses; bul many died, and the experiment proved unsatisfactory. Consequently 

 those thai survived were turned adrift to shift for themselves. During the 

 period occupied by the Boundary Survey some camels were known to exist, 

 most of them north of the Gila River, in southwest Arizona. We saw a skel- 

 eton of one on the Tide Desert, bill no living camel. [For an account of the 

 introduction of camels and dromedaries into Texas, see Attwater, Hull. Am.
