In concluding these tedious, but in the present state of science, indis- 

 pensable details, we may be permitted to enquire whether they suggest 

 or lead to any general principles or facts? Whether, for instance, they 

 justify our separation of the Gouri Gao as a distinct type among the Bovi- 

 nae ? and whether, as well with reference to the introduction of this new 

 form as to the obvious vagueness characterising the extant definitions of 

 the other forms, these details suggest no feasible improvements upon 

 those definitions ? 



Both these questions may 1 think be fairly and usefully answered in 

 the affirmative and I shall terminate this paper with the following im- 

 proved indications of the principal Genera or groups of the Bovinee. 



Bos. Cranium moderate, proportional or without excess in the cere- 

 bral or facial region : frontals shorter than the face, flat and not broader 

 than long. Occipital plane of the scull quadrangular, never arched along 

 the culmenal line, nor indented by the temporal fossee ; smaller much
