Show 58 MESSRS. DANFORD AND ALSTON ON [Feb. 3, But on examining two other pairs of horns from the same locality, in Danford's own collection, we find that they do not present the peculiarities of the British-Museum skeleton, but agree excellently with Blyth's type. In these horns (one pair of which are represented in figs. 2, 5) the terminal portion is only gently bent upwards, the sculpture is small and sharp, the fronto-orbital edge is not distinct, except at the base, and the orbital surface is strongly convex^ throughout, so that towards the middle of the horn it runs almost insensibly into the frontal surface. As it is hardly possible that two closely allied species should be found together on the Cilician Taurus, the above comparisons appear to us to be of some importance, as illustrating the wide range of variation in the form of the horns in one species of Wild Sheep, and the consequent necessity of examining a large series of specimens of such animals before deciding as to their specific identity. When such series are available from different localities, we suspect that some of the recently described new species will prove to have been founded on individual varieties. With a view to contributing to such material, we have had the accompanying figures prepared, and have drawn up the following list of the specimens examined, with a table of their principal measurements. a. A n enormous head in the British Museum, presented by Mr. W . Burckhart Barker, and said to be from " an island in the Mediterranean" (!). b. Skin with horns. Erzeroom, Dickson and Ross, in the British Museum. One of the types of Blyth's 0. gmelini, the others being a ewe and a lamb (figs. 1, 4, pp. 56, 57). c. Horns, Cilician Taurus, in Danford's collection (figs. 2, 5, pp. 56, 57). d. Horns, Cilician Taurus, in Danford's collection. e. Skeleton, Cilician Taurus, Danford, in British Museum (figs. 3, 6, pp. 56, 57). MEASUREMENTS. Length of horn along curve of fronto- Circumference at one half of length ...

The males in both cases have no white saddle-mark ; and the females are hornless. Dr. Straueh informs us that the original type specimen of S. G. |
