The pedicels have an altogether horizontal direction, are some- 

 what longer than in the moose, and show a deeper posterior con- 

 striction, to allow the unobstructed movement of the coronoid 

 process. The burrs are quite widely separated, almost an inch 

 more than in the specimen described by Dr. Wistar. The beam 

 is directed horizontally outwards, as in Alces, even drooping a 

 little, as noticed by Leidy, and is unusually long before reaching 

 the point of branching. Leaving out of account for the present 

 the peculiar portion of the antler, it obviously belongs to the 

 palmated dichotomous t}'pe of Alces. The ordinarily accepted 

 view with regard to the antlers of that animal is that brow-antlers 

 are not present. Sir Victor Brooke, however, considers the 

 anterior division of the antler the homologue of the brow-branch 

 (P. Z. S., 1878, p. 915). Assuming the correctness of the ordinary 

 view, the fossil form agrees with the recent in being devoid of 

 the brow-branch. The main antler is divided into two palmated 

 portions, of which the anterior is the smaller, though it is both 

 proportionally and absolutely much larger than in the moose 

 (figs. 5 and 6, A). This portion is twisted on itself so that its 

 flat side is presented forwards in a plane almost at right-angles 

 to that of the posterior division. The palmation of this anterior 

 portion is somewhat more pronounced, and the tines more flat- 

 tened than in the moose. In the figures all the tines appear 

 somewhat blunt, though this is due to the fact that the animal 

 died while the antlers were yet in " the velvet." In the moose 

 the division into the two palms takes place in a plane only a littie 

 above the level of the frontal ridge (2^ in.), in the fossil the beam 

 turns sharply upwards for several inches (6i) before the point of 

 separation is reached. The appearance of the anterior branch is 

 very different from what is seen in the moose. In the specimen 

 before us there arises from the point of division a narrow flat 

 plate somewhat twisted on itself, which gives off a sharp and 

 stout lateral tine, two or three inches above the point of division ; 

 above this tine the plate broadens for a little distance and then 

 bifurcates. On the right side both of these divisions are again 

 bifurcated, the outer one much more deeply than the inner ; on 

 the left side the inner prong does. not divide, though it is broad 

 and flat. This gives five prongs on the right side and four on the 

 left. Except the lateral tine, all the tines are flattened antero- 

 posteriorly, having a plate-like appearance from the front.
