Sp. Char. Vertebra 3 four incbes bigb, three-quarters of an inch in length, and 
with a transverse diameter of more than two inches. Outline of the centrums oval, 
with a slightly concave surface. Teripheral fissures very narrow and numerous; margins 
of the centrums prominent and rounded. 
Ohs. The present very remarkable specimen consists of seven vertebrae of a 
Selachian fish, firmly united together, but slightly displaced obliquely from their normal 
position, and as a whole six inches in length. In all probability, from the difference in 
the height and transverse measurement, these vertebrso had to some extent an oval 
outline, but this may have been intensified by the oblique displacement they have 
undergone. 
With our present unsatisfactory knowledge of the remains of this group of fish 
in bygone periods, it is difficult to decide on a genus for these remains, but there is a 
general correspondence to the excellent figures given by Agassiz of the vertebra of 
extinct species of Lamm, for it is quite clear that the whole of each centrum was ossified, 
as in the family represented by the genus in question. According to Agassiz’s statement 
as to the number of the peripheral fissures, in the anterior, posterior, and abdominal 
regions of the column, the present specimen would be those of the abdominal. 
It must be the representative of a very large fish. The Australian Museum 
contains a Carcliarodoii Rondeletii, about nine feet long, with vertebrse the centrums of 
which are about half the size only of those in this fossil. Judging by these measure- 
ments, it would appear to Mr. J. Douglas Ogilby, who has kindly gone into the question 
with me, that we have here the remains of a fish which must have been from eighteen 
to twenty feet long. '
