2. Sylvilagus Artemisia, Bachm., Waterh. Gl. 126; Baird, N. 
A. M. 602. (ZL. artemisianus, Wagner. ? L. Nuttalli, Bach., 
Aud. N. A. Q. t. 94.) Sage Rabbit. New Mexico. B.M. 
** Soles of feet very sparsely furred. 
3. Sylvilagus Bachmanni. (Lepus Bachmanni, Waterh. P. Z. 8. 
1838, p. 103, Glir. 124; Aud. N. A. Q.t. 108; Baird, N. A. M. 
606.) : 
3. Euracos. Skull rather elongated; face broad, rounded 
above; the intermaxillary bones form a ridge on each side; 
anterior orbital notch narrow; postorbital aperture oblong, 
elongate, narrow, behind complete from the coalescence of the 
hinder end of the postorbital process with the skull. Grinders 3, 
the hinder upper grinder very small and very close to the pen- 
ultimate, which has caused it to be overlooked. 
1. Eulagos mediterraneus. (Lepus mediterraneus, Wagner, 
Waterhouse, Glires, 48. L. meridionalis, Géné. L. granatensis, 
Schimper. L. timidus, var. c, Blasius, Saugeth. Deutschl. 412.) 
Tunis, Fraser. B.M. 
Mr. Waterhouse overlooked the hinder upper grinder; and 
Blasius confounded this very distinct species with L. timidus. 
Length of skull 8 inches 3 lines, width at zygomata 1 inch 
5 lines, of nose in front of orbit 9 lines. The upper edge of the 
orbits narrow, ascending. 
2. Kulagos Judee. The Holy Land Buneas, Tristram, B.M. 
The skull is much larger than that of E. mediterrancus, nearly 
as large as that of the common hare, Lepus timidus. Length 
of skull 3 inches 10 lines, width at zygomata 1 inch 9 lines, at 
front of orbits 1 inch. The upper edge of the orbits wide, 
expanded, forming a concave hood. 
II. Postorbital process separate from the skull. 
4, Lepus, Linn. Lepus §§ A & BH, Baird, N. A. M.575. Skull 
narrow, slightly curved above ; face margined by the upper edge 
of the intermaxillaries. The front lower edge of the zygoma swol- 
len, rounded, solid. Postorbital process very large, the hinder 
part nearly parallel with the skull, but separated from it by a 
slit. Grinders $+, hinder upper very small; cutting-teeth 
narrow, upper with a central groove. Born covered with hair, 
and the eyes open. Lives on the surface or behind stones.
