10. Hozobn.—At a meeting of the Natural History Society of Mon- 
treal in January last, Dr. Dawson exhibited a photograph of a remarkable 
specimen of Hozoén Canadense, found the past summer in the Lauren- 
tian limestone of Tudor, Canada West, by Mr. Vennor, of the Canadian 
Geological Survey, and which had been examined and described for Sir 
Logan by Dr. Dawson. The rocks at Tudor and its vicinity, which, 
according to the observations of Mr. Vennor are Lower Laurentian, have 
experienced less metamorphism than is usual in neat of that age, 
and this peculiarity gives especial interest to the present specimen, which 
is contained in a rock scarcely altered and in a condition ae essentially 
different from that of ordinary Silurian fossils. 
The matrix is a coarse laminated limestone of a dark color, and con- 
taining much sand and finely comminuted carbonaceous matter. The 
fossil itself is of a flattened clavate form, about six and a half inches in 
length, and with the septa of its chambers perfectly preserved, exhibiting 
on one side a well defined marginal wall produced by coalescence of the 
septa, and apparently traversed by small orifices. Un ae r the microscope 
the minute structures of Hozod “ene can be detected, though less 
included in the serpentinous limestones, and as cectioelag the prs 
tions raised i in some quarters to the or ganic it of f Hozoon. The s ci-

(from a notice of the meeting of 0 California Academy, Aug. 20, 1866.) 
—Prof. Blake read a paper upon a “ New ee vm Fossils in the Gold- 
ing Rocks of California,” and exhibited specimens of Ammonites from 
a cut on the line of the Central Pacific Railroad, near ‘ar Colfax. Although 
thes sen exe was quite perfect, it was not sufficiently so to ena- 
ble seen. Prof. Blake remarked that these fossils were 
atenholy: of. the secondary period, and that they were apparently spe- 
cifically identical with those from the American river, in the same vicinity,
