The Terebriporce have been very carefully investigated, and have had their 
distribution defined by M. Fischer, who has published an important paper 
on the subject. His inquiries extended also to the distribution in time of these 
organisms, and indicate that the Terebriporce are different in the secondary 
and tertiary beds. He has detected four or five species in the former and as 
many in the latter. In September, 1865, he luckily found in the Harbour of 
Arcachon an oyster perforated by a colony of Terebriporse, and he has found 
them since in the Mediterranean. Besides Terebriporce, M. Fischer has found 
on the coasts of the Gironde a Bryozoan belonging to the same family and 
having the same habits, but differing in having its cells borne upon alternate 
axes. It leaves upon the shells elegant impressions resembling the ramifica- 
tions of the Sertularice. He proposes to name it Spathipora. The living- 
Spathiporse are not numerous. There are only two living species known, 
one from the coasts of France and the Mediterranean, the other from the 
Pacific. — Yide Quarterly Journal of Microscopical Science, July. 
Two extreme forms of Human Crania were exhibited by Professor Huxley 
at the Biological Section of the British Association. The first was the skull 
of an adult form from the collection of the Royal College of Surgeons, and 
exhibited unusual breadth and round, the breadth being °f its length.. 
It was arched, and the jaws did not project. The palate was short and broad, 
and the suture joining the two parietal bones was completely obliterated, the 
other sutures being still open. The second skull was said to have come from 
New Zealand, but of this Professor Huxley was doubtful, as it did not pre- 
sent all the features of the Australian type. It was the narrowest skull, in 
proportion to its breadth, that he had seen recorded, the breadth being only 
tVA of the length. The first was arched and dome-like, and the contours 
almost semicircular, whilst the second had compressed and wall-like sides, and 
was roofed in like a house. The occiput of the second was remarkably flat- 
tened, the jaw projected very far, and the palate was very long and broad. 
Although there was a great deal of dissimilarity, the two agreed in cer- 
tain particulars. The length of the basi-cranial axis was nearly the same, so 
that it may be concluded that the length of the axis of a skull has no neces- 
sary relation to its absolute or relative breadth. 
The Angola in the Colony of Victoria. — Three years ago the Acclimatisa- 
tion Society of this colony communicated a series of experiments on the 
subject of the value of Angola wool, and having been convinced of its com- 
mercial importance, they proceeded to introduce ninety-three specimens. The 
animals are spreading rapidly, and it is thought the Angola wool will have as 
high a value as the Merino wool has at present. 
The Acclimatization Society of Paris has been presented by General 
Khereddin, of Tunis, with a magnificent collection of animals. The series 
consists of a fawn of the deer of Barbary, three goats to supply it with milk, 
six gazelles, a fox, a jackal, and several birds, amongst which may be named 
— a superb ostrich, a bustard, two wild pigeons, three falcons trained to fly 
at hares, two sparrowhawks trained to fly at quails, an eagle, a yellow vul- 
ture, &c. The eagle and the vulture were offered to the Museum of Natural 
History in the name of His Excellency the General Khereddin. The falcons 
and sparrowhawks have been placed in the hands of M. Barr, the able falconer 
of M. Alfred Werle, of Rheims, who will put them into training, and try
