From the offset of the supra-basilar, the beam and its main 

 branches are broad and compressed, but nowhere to the 

 extent of pagination ; the section yielded by the former, being- 

 ovate, with constriction in the three intervals between the 

 offsets of the successive antlers. The beam and its branches 

 are boldly and closely channelled, the grooves being con- 

 tinued out on the flattened sides of the long straight tynes ; 

 but they are alike free from pearly rugosity. 1 



The two most striking characters about the horn consist : 

 1st. In the enormous spread of the tynes of the median and 

 royal antlers, straight outwards from the beam, as compared 

 with the length of the latter. 2nd. In the symmetrical direc- 

 tion of the elongated tynes of the median and royal antlers, 

 which diverge forward in the same vertical plane. 



The supra-basilar, or master-antler, being the lowermost 

 antler, is thrown forwards and outwards, at right angles to 

 the beam, its upper edge being about 6| inches above the 

 bur. It is flattened for about 5 inches, and then bifurcates ; 

 each division again bifurcating, so that there are three forks 

 and four snags, which are all in nearly the same vertical plane. 

 The upper branch is directed nearly straight forwards, the 

 lower inclines downwards. The snags are of unequal length, 

 the uppermost or fourth being little more than an elongated 

 tubercle. The tip of the second snag, which is above entire, 

 stretches out about 17 inches from the beam. The expansion 

 of the third snag, which is wanting, must have been greater. 

 The first snag is also wanting, being broken off at its base. 2 



The second or median antler is thrown off about 6 inches 

 above the supra-basilar. It is directed straight forwards 

 from the anterior edge of the beam in a flattened branch, 

 which, after stretching about 6 or 7 inches, bifurcates, the 

 upper lobe consisting of a single, straight, flattened, conical, 

 and slender tyne of great length, which inclines slightly 

 upwards, an intermediate piece near the tip being wanting ; 

 while the lower lobe forms a flattened branch, which again 

 bifurcates at about four inches. The upper tyne is directed 

 straight forwards at right angles to the beam, and attains 



upon the inner side the convexity of the 

 section is continued uniformly upwards 

 a little above the supra-basilar antler, 

 while upon the outer side it is flattened. 

 On examining the continuation of the 

 beam immediately below the terminal 

 section it is seen to be less flattened than 

 the royal, the section measuring about

1 Extract from Note-book. — ' The 

 channelling is much more boldly deve- 

 loped upon the inner side than upon the 



outer.' — [Ed.] 



2 Extract from Note-book. — ' The su- 

 pra-basilar antler, as a whole, is some- 

 what concave, the concavity being in- 

 wards. When the horn is laid flat, the 

 common plane of the supra-basilar is 

 raised some inches above that common 

 to the median and royal antlers. The 

 section of the supra-basilar is much less 

 flattened than that of the median and 

 royal, the section forming an oval, convex 

 outwards and flattened inwards.' — [Ed.]
