fElem. de Zoology.} 



Goodrich, in his Geography, enumerates the following species in the United 

 States, viz: 



1. The American Elk, or Wapiti, C. Strongyloceros. 



2. The Moose, C. alces Americanus. 



3. The Caribou, or American Reindeer, C. tarandus. 



4. Common Deer, C. Virginianus. 



5. The long-tailed Deer, C. leucurus. 



6. The black-tailed or Mule Deer, C. macrotis. 



The tegumentary appendages of all these species, so far as we have had an opportunity 

 to examine them, have a great sameness of structure ; sufficiently so to connect them into 

 one group. The cortex is, paved, the divisions have the shape of compressed pentagons, 

 octagons and polygons ; the coloring matter lies immediately beneath the cortex, the centre- 

 being colorless, and the shaft having no canal ; the button is spindle-shaped, succeeded by 

 a slender neck, the shaft is feebly flexible, bending at right angles; the ductility very 

 considerable, but accompanied with little elasticity or tenacity.* 



We will now give a particular description of a hair of one of the species. 



1. The Stag or Deer, Cervus elephus. Specimen from the Western part of the State. 

 Hair. Length, about 2 inches; greatest diameter, fa, and least diameter, T ^ of an inch ; 

 button, spindle-shaped ; length, fa of an inch, and diameter, T |^ of an inch. Neck. 

 Length, fa of an inch; diameter, %%-$ of an inch, gradually widening to a stalk. f Apex, 

 gradually tapering to a point ; color, for one inch and -fa white, opaque, gradually darken- 

 ing for -J&0- of an inch, succeeded by light brown or fawn color, and terminating in black at 

 the apex. The whole stalk is undulated, the highest waves of which are in the centre. 

 The interstices between the paved portions, darker colored than that of the pavement ; 

 flexibility feeble, bends at right angles, and remains bent. No central canal. 



Ductility, Elasticity and Tenacity. May llth, 1849. One inch with 170 grains was 

 deprived of its undulations. Upon removing this weight the undulations returned. 

 With 180 grains it stretched -fa of an inch, elasticity entire.

* Perhaps a large portion of the animal vitality conveyed to the exterior is expended on the horns. 



t When the part that widens is observed on its flat sides, the paved cortex is seen on it; while on the elipsoids the cortex 

 appears plain.
