rations and Adventures in Equatorial Africa” (p. 243), 
in the following passage :— 
“Before we got to town again, I shot a #boyo, a very 
shy animal of the wolf kind, with long yellowish hair, and 
straight ears. I have often watched these beasts sur- 
rounding and chasing small game for themselves. The 
drove runs very well together, and as their policy is to 
run round and round, they soon bewilder, tire out, and 
capture any animal of moderate endurance.” 
Such is M. Du Chaillu’s fragmentary notice of this 
animal, of which, however, he does not appear to have 
sent home specimens. After endeavouring in vain to find 
a name for this distinctly-marked species of Cazzs, which 
is readily recognisable by the black and white stripes 
along the flank, and the long black tail with a black ter- 
mination, I proposed at the meeting of the Zoological 
Society, on May 12th, to call it Cams lateralis. Dr. 
Peters, however, has since suggested to me that it may 
be the Canis adustus of Sundeval, and this identification 
is probably correct, although our example does not agree 
very well with Sundeval’s description. I may also remark 
that there is no example of Cazzs adustus in the British 
Museum, and that, without the aid of specimens, the 
differentiation of the various species of Caz7s is by no 
means an easy task. 
In the month of May the number of additions to the 
Society’s collection of living animals was still more nume- 
rous than in April, amounting altogether to 200. Of these 
fifty-four were received as presents and cighty-three 
acquired by purchase ; forty-five were bred in the gardens 
and eighteen were deposited for safe custody. The 
number of departures in May, by death or otherwise, was 
seventy-five. 
Amongst the 200 acquisitions in May were several of 
great interest, viz. :— 
1. A male deer, forwarded to the Gardens from Singa- 
pore by order of H.R.H. the Duke of Edinburgh. his 
is quite different from any other deer yet obtained living 
PRINCE ALFRED'S DEER (Cervus adfredz) 
by the Zoological Society. It is obviously allied to the 
axis or spotted deer of continental India, and may be the 
Malayan form of that species. It differs, however, in its 
smaller size and smaller ears, and in the dark coffee-brown 
colour of the fur. I have not been able to find any desig- 
nation applicable to it, and, at a recent meeting of the 
Zoological Society, have proposed to callit Cervus alfredz, 
after the Prince, who has transmitted the present indi- 
vidual to us. 
2. Three examples of the crested or bladder-nosed 
seal of the Arctic Seas (Cystophora cristata), purchased 
May 5, out of a whaling vessel, which brought them into 
Dundee. These are the first examples of this seal that 
have reached the Society’s gardens alive, and are of much 
interest, as making us acquainted with the external form 
of a very distinct genus of the Phocide. The bladder- 
like excrescence on the forehead, which attains an 
extraordinary development in the adult male, is but very 
slightly shown in these young animals, but a look in the 
mouth at once shows their difference from the typical 
seals of the genus Phoca. 
3.. A huia-bird (Heteralocha gouldi), from New Zea- 
land, purchased May 18th. This bird is remarkable for 
the great difference in the shape of the bill between the 
two sexes, as will be readily understood, by reference to 
the accompanying illustration, in which the short-billed 
individual is the male and the long-billed the female. The 
| figure of the male is taken from the Zoological Society” 
specimen, the head of the female is copied from Mr. 
Gould’s plate of this species in the “ Birds of Australia.” 
Such a divergence in the structure of the beak of the two 
sexes is very uncommon and scarcely to be paralleled in 
the class of birds. It is difficult to guess at the reason of 
it, or to explain it on Darwinian or any other principles. 
The story is that the male employs his stronger instru- 
ment to hew away the wood that covers the grub, and the 
female her more delicate organ to extract the precious 
morsel. Unfortunately, we have as yet only one sex of
