Before passing to the consideration of certain intestinal peculi- 
arities, I cannot omit noticing a few additional points of general 
interest. As in the aged animal, so also in the young individual, 
the cerebellum is situated on a level with, and is not overlapped by, 
the cerebrum. In the Edinburgh specimen I found the rudimental 
uvula to consist of three small, conical, and closely approximated 
papillee, but in the present example there are only two minute pro- 
cesses of a similar character, united at the base and subsequently 
diverging from one another at right angles. From former exami- 
nations, I feel quite certain that the fibres of the ligamentum nuche do 
not exhibit, under the microscope, any transverse striation, neither 
in the fresh state nor when dried, and I cannot but suppose that the 
appearances indicated by Prof. Quekett must have been accidental. 
Except in the truly anomalous instance described by Prof. Owen— 
where a double gall-bladder occurred in a female—all previously 
recorded dissections of the giraffe point to the absence of a gall- 
bladder ; and this rule, which also holds good in the case before us, 
very strongly indicates the Cervine affinities of the genus. 
_ Without entering upon a minute description of the parasites 
infesting the Giraffe, I may here notice that a careful scrutiny of 
the viscera of the Society’s young specimen has enabled me to add 
yet another species to the list.of Entozoa. From the liver and sub- 
lingual cellular tissues of the Edinburgh specimen I obtained nume- 
rous Cysticerci and Cercarie, together with about forty examples of 
an unusually large fluke* ; and though neither of these helminthic 
forms existed in the present instance, the cecum was nevertheless 
abundantly supplied with Trichocephali, markedly different from those 
so commonly found in man. Provisionally, I recognize this nema- 
tode entozoon under the combined generic and specific title of 
Trichocephalus gracilis+. 
In regard to certain peculiar modifications of structure found in 
the alimentary canal, I have, in the first place, to remark the 
presence of valvular folds at the anterior border of Peyer’s glands. 
All the agminated follicles or patches do not exhibit this smgular 
folding, only three or four of the glands being thus extended; in 
these, however, the duplication was even more developed than re- 
presented in my original figure in the Article “‘ Ruminantia”’ previ- 
ously cited. In the Society’s young giraffe, also, the lateral margins 
of the glands are more elevated, whilst well-marked transverse ridges 
pass across the follicles from side to side. Morphologically speak- 
ing, these rudimental partitions undoubtedly represent the lobular 
foldings of ordinary compound glands—a view which is more clearly 
brought out by considering the complexity of that unique differen- 
tiation which I have next to notice. From the juvenile character of 
the Society’s animal I scarcely expected to detect more than a mere 
* Fasciola gigantea mihi, in Mem. loc. cit. 
+ From other animals which have more or less recently died at the Society's 
Menagerie, [ have procured a variety of interesting Entozoa. See two Memoirs 
in the Linnean Society’s Transactions, vol. xxii. pp. 155, 363. Plates 31-33, 
and 63.
