638 ON THE ANATOMY OF THE CHINESE WATER-DEER. [Nov. 14, 
reticulum-cells are rather shallow. The psalterium has, as I count, 
nine primary lamine, and is quadruplicate. 
The length of the intestines in the present specimen (the body of 
which had a total length of 33 inches, including the three-inch- 
long tail) was 29 feet 2 inches, 21 feet 7 inches being small 
intestine, the remainder (7 feet 7 inches) colon and rectum. The 
relative lengths, therefore, of these parts were not very different from 
those that obtained in the younger individual already described. 
The czecum was three inches long. There were 23 coils in the colic 
spiral ; and at the junction of the ileum and cecum is a distinct 
glandular patch, like a largish ‘* Peyer’s patch,” though not having 
the complex structure of the ileo-czecal gland met with in Moschus, 
Cervus, Camelopardalis, &c. 
The only figure hitherto extant (that given by Prof. Garrod in 
his paper already quoted) of the brain of Hydropotes having been 
taken from a very young specimen, it may be worth while to give 
figures of the superior and lateral aspects of that removed from this 
adult specimen, which will be useful for comparison with Garrod’s 
earlier one, as well as with those given by that author and Prof. 
Flower of the brain in Hlaphodus, Moschus, and Pudua, and with 
the series of semidiagrammatic sketches illustrating Dr. Krueg’s 
valuable paper on the cerebral convolutions of the Ungulata gene- 
rally 1, whose nomenclature on the subject I have also adopted. 
In its cerebral organization Hydropotes approaches the genus 
Capreolus more nearly than any other Cervine form known to me, the 
similarity of the two being obvious on comparison of the figures now ex- 
hibited (seep. 637) with those of Leuret and Gratiolet * and of Krueg* 
of the Roe. From Elaphodus and Pudua these two forms differ in 
the entire disappearance (save very slightly anteriorly ) of the calloso- 
marginal (‘ splenial ’’) sulcus from the superior aspect of the hemi- 
spheres, owing to the greater “ pronation”? of their brain generally. 
Sir Victor Brooke has been led, from a consideration of other 
points *, to associate Hydropotes and Capreolus with Alces, as a 
roup per se, with affinities in some points in the direction of the 
Old-World (Plesiometacarpal), in others in that of the New-World 
(Idiometacarpal) forms. It appears to me that the additional evi- 
dence in this paper, especially that derived from the resemblance of 
the generative organs, is strongly in favour of this association, 
so far, at least, as Hydropotes and Capreolus are concerned. The 
general similarity in facies of Capreolus to Hydropotes has often 
struck me, and has even, I believe, led others into the error of 
mistaking one for the other! 
That Hydropotes is in no way intimately related to Moschus 
was already amply demonstrated ; and the latter form also differs, 
as we now know, in the conformation of its glans penis and in the 
possession of Cowper’s glands.
