706 On Various Genera of the Ruminants. [July, 



Horns attached to highest line of forehead, more or less depressed, 

 and angular, and directed upwards and outwards with little curvature. 



A true dorsal ridge but confined to the withers. 



Mnfle moderate. 



Dewlap moderate. 



Thirteen pairs of ribs. 



Type. Bos frontalis vel Gayceus vel Sylhetanus. 



The Gavi or Gabi. Habitat trans-Brahmaputram, the forests under 

 the ranges extending from Assam to the sea. The Senbar vel Phain 

 may probably be a second species, and Bos Sondaicus or the Benteng, a 

 3rd, and the insular species : but these want testing. The first is more 

 than half redeemed from the wild state, like the Yak of Tibet. The 

 others are entirely wild. I possess no memoranda of the soft anatomy 

 or intestines, nor of the breeding season and gestation. 



3. Genus Bibos. 



Gaur, or Gauri Gau. 



Cranium large, massive, with the frontal and cerebral portions pre- 

 ponderant over the facial. 



Frontals as long as the face, broader than long, concave and sur- 

 mounted by a salient arched crest. 



Occipital plane spheroidal, very large, larger than the frontal plane, 

 deeply indented centrally by the temporal pits, and forming an acute 

 angle with the frontal plane. 



Orbits salient. 



Condyles of great foramen and of lower jaw low, and the latter 

 straight. 



Horns attached below crest of forehead, sub-depressed, sub-angular, 

 and curving ascendantly. 



Thirteen pairs of ribs. 



Dorsal ridge co-extensive with the ribs, and of great elevation. 



Mufle small. 



Dewlap small. 



Type. Bos Gaurus vel ? Cavifrons. The Gaur or Gauri Gau. Caesar's 

 wild Bull of Europe and Aristotle's of Persia, are two other species of
