386 ON LOPHOTRAGUS MICHIANUS. 
The colic coil was not disposed in quite the ordinary manner; but 
the peculiarity was probably an individual one. At its end the large 
intestine made a complete transverse reduplication before turning © 
forward from the right iliac fossa to form its terminal and irregular 
curve round to the sigmoid flexure. 
The spleen is flat on one side, domed on the other, and circular. 
The liver is composed of two nearly equal lobes, from the abdomi- 
nal surface of the right of which is developed the triangular and 
laterally directed caudal lobe. The Spigelian lobe is only rudimen- 
tary, being represented by a slight tumefaction of the vertebral border 
of the portal fissure. There is no gall-bladder: 
In the arteries of the neck the arrangement is that found in the 
Ruminantia generally, the ascending aorta giving origin, first to the 
left brachial with the corresponding vertebral, then to the left carotid, 
and finally to the same three vessels of the right side. 
There are thirty-eight tracheal rings above the accessory bronchus 
and nine below it, making forty-seven in all. In the lungs the 
two lobes of the left side and the five on the right were found, the 
right lung being the larger. The lower lobe of each lung is com- 
paratively small. 
The brain (figs. 1 and 2) is richly convoluted for its size, its mea- 
surements, after having been hardened in spirit, being :—

It is therefore somewhat larger than in Cervus humilis, as may be 
inferred from the measurements given by Professor Flower*. This 
species it also closely resembles in its convolutions, as well as in the 
considerable development of the anterior lobes. The hippocampal, 
inferior external, together with superior and middle external gyri, are 
easily recognizable, the sulcus separating the last two being long, and 
the middle external gyrus traversed in the direction of its length by 
a minor sulcus. ‘There is a break in the sulcus which separates the 
middle and inferior external gyri a little more than an inch from the 
anterior border of the hemisphere, which is peculiar. As in Moschus 
and in Cervus humilis, the calloso-marginal sulcus appears on the 
superior surface of the brain, allowing the hippocampal gyrus to 
appear between it and the middle line. In Cervulus muntjac the convo- 
lutions are slightly less developed than in Michie’s Deer, and the
