162 MR, F. E, BEDDARD ON 'THE [ Feb, 16, 
parietes by matted ligamentous cords in both Llephas africanus 
and #. mavimeus. M. Giard goes on to suggest that the same may 
be the case with /7yrax capensis, quoting “apparently confirmatory 
evidence from the well known memoir of George upon that 
animal, tL myself am unable to contirm this suggestion from my 
dissections of several examples of both J/Zyrax capensis and 
/, dorsalis, Still there remains the Elephant, which seems most 
undoubtedly to resemble the Indian Tapir in this remarkable 
specialisation, Lt is difficult to form an opinion as to whether 
any stress is to be laid upon the fact that both these animals are 
Ungulates. 
(2) Votes upon the Brain and some other points in the 
Anatomy of Hyrax. 
The Society acquired some months ago the temporary posses- 
sion of a considerable number of examples of LHyraxe capensis, 
which were all about half-grown. ‘The measurement of one 
individual (and all were of about the same size) was a foot or 
so in length. The dissection of so large a series of specimens has 
enabled me to add some facts to what is already known about the 
structure of this primitive Ungulate. I she ull deal with sueh 
organs as T have specially investigated seri@éim, and shall in some 
cases be able to compare ‘them with the corr esponding organs of 
iH. dorsalis, of which I have dissected two examples. 
A Tygos ve in.—l have already deseribed * the condition of this 
vein in Zyrax and quoted the descriptions of others. Tt is 
evident from what has been written on the subject, that the 
prevailing arrangement in /Zyra@v is the presence of a single 
azygos only, and that on the right side. In all the examples to 
which the present note refers, thisarrangement of the azygos was 
found. The comparative constancy of the azygos, Upon ‘whieh I 
have already ventured to insist, is thus established for the present 
species. 
The Brain of A yrax has been figured by several anatomists. 
Thus Serres gives in his ‘ Anatomie ‘Comparée du Cerveau’ fF two 
views of the brain. Later Dareste reported { upon three brains 
which were not very well preserved. Of these he wrote that they 
*seloignaient du type des Pachydermes pour se rapprocher de 
celui des Carnivores "—no hint, here, it will be noted, of any 
Rodent attinities. Some years later Gervais § figured a cast of the 
brain in his well-known paper upon the mammalian brain, The 
most complete series of figures known to me of the brain of this 
*Subungulate ” are those of George in his monograph || wpon 
Hyrex. The brain is figured in many views and very thoroughly. 
The brain of Wyrax is also figured by Sir Richard Owen in his
