Ceryotinz. Small Cervide in which the ‘proportionally small 
' antlers are situated on elongated pedestals, up the front of which 
the lengthy hair of the crest which is developed in the frontal 
region extends. Females hornless. Suborbital glands large in 
both sexes. No metatarsal tufts. Canine tusks large in the 
males, minute in the females. The second and third cuneiform 
bones of the tarsus ankylosed with the naviculo-cuboid. The 
lateral metatarsals wanting, and the lateral metacarpals present 
only as slender bones opposite the upper ends of the third and 
fourth metacarpals, or wanting altogether. 
Two genera are contained in this subfamily. 
Cervulus. Cervuline in which the pedestals of the antlers are di- 
vergent, and send downwards from their roots strong supra- 
orbital ridges, the antlers themselves diverging into a brow-antler 
and a simple beam. Cutaneous glands developed on the inner 
side of each supraorbital ridge. 
Elaphodus. Cervuline in which the pedestals of the antlers are con- 
vergent and do not send downwards supraorbital ridges. Antlers 
minute and simple, scarcely projecting beyond the much-developed 
frontal hair-tuft. Frontal glands.absent.

LOGY OF THE RUMINANTS, WITH A SUGGES- 
TION REGARDING A METHOD OF EXPRESSING 
THE RELATIONS OF SPECIES BY MEANS OF 
FORMULZ:.* 
THERE is so little known of the differences in the visceral anatomy 
of the many genera and species of the ruminating animals, that I feel 
that no apology is necessary for bringing before this Society the facts 
which my prosectorial opportunities afford me with reference to parts 
which are either too large or too perishable to be easily preserved in

account of those parts in’ certain species of the Cavicornia and Cervidee 
-(such as the stomach, liver, generative organs, and brain), which are 
subject to variation in the different species that I have had the oppor- 
tunity of examining.
