3738. The skull of a young Goat (Copra Hircus). 



The deciduous molars and the first and second true molars are in place : the three pre- 

 molars (p 2, p 3 & p 4) are exposed in their formative sockets on the right side of both upper 

 and lower jaws, and also the last trilobed molar of the lower jaw. 



Purchased. 



3739. The horns, somewhat malformed, of a common Goat (Copra Hircus). 



Hunterian. 



3740. The horns of the Angora variety of the Goat (Copra Hircus). Purchased. 



3741. The horns of the Iceland, or four-horned, variety of the Goat (Copra Hircus). 



Mm. Brookes. 



3742. The skull, with the dried skin and horns, of the Ibex (Copra Ibex). 



The horns are very long and large, with a gentle curve upwards, outwards and backwards, 

 in nearly the same plane : their fore part is square or flattened, with prominent transverse 

 ridges. 



Hunterian. 



3743. The horns of the Caucasian Ibex (Copra Cancasica). 



The horns are obtuse, not squared, in front, but are similarly ridged transversely. 



Mus. Brit. 



3744. The frontlet and horns of the male Copra JEgagrus. 



The long diameter of the base of the horn is placed obliquely to the axis of the skull, the 

 bases of the pair converging anteriorly. The annual rings of growth are well shown in these 

 horns, owing to the beak-like process, which bends down from the fore part of each ring, 

 forming the undulating anterior ridge of the horn. This process is seen in the four lower 

 rings ; that of the fifth is shorter, and it is not distinguishable in the apical segment. These 

 segments, successively and annually pushed upward from the base of the horn, answer to the 

 antlers which are successively developed and shed in the Deer-tribe. 



Purchased. 



3745. The frontlet and horns of a smaller individual of the Copra ^Egagrus. 



Each horn has eight rings, the last-formed one being much shorter than the rest. 



Purchased. 



3746. The horns of the variety of the Wild Goat called Copra jflyagrus by Pallas. 



Each horn has six irregular nodules on the anterior surface, more widely apart from each 

 other than in the Capra JEgagrus of Cuvier, of which, if the animal be not specifically distinct, 

 it must be a well-marked variety.
