 A. M. 602. {L. artemisianus, Wagnev. "^ L. Nuttalli, Ba.ch., 

 And. N. A. Q. t. 94.) Sage Rabbit. New Mexico. B.M.

3. Sylvilagus Bachmanni. {Lepus Bachmanni, Waterh. P. Z. S. 

 1838, p. 103, Glir. 124 ; Aud. N. A. Q. t. 108 ; Baird, N. A. M. 

 606.) 



3. EuLAGOs. 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 5, 

 the hinder upper grinder very small and very close to the pen- 

 ultimate, which has caused it to be overlooked. 



1. Eiilagos mediterraneus. {Lepus mediterraneuSy Wagner, 

 Waterhousc, Glires, 48. L. meridionalis, Gene. L. granatensis, 

 Schimper. L. timidus, var. c, Blasius, Saugeth. Deutschl. 412.) 

 Tunis, Eraser. B.M. 



Mr. Waterhouse overlooked the hinder upper grinder ; and 

 Blasius confounded this very distinct species with L. timidus. 



Length of skull 3 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. Eulagos Judcece. The Holy Land Buneas, Tristram, B.M. 

 The skull is much larger than that of E. mediterr-aneus, 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. Tostorbital process separate from the skull. 



4. Lepus, Linn. Lepus §§ A & E, 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 5 -r, 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.
