organisms, together with the Graptolites, have caused the Moffat 
Shales to be referred without doubt to the Llandeilo Flags. 
Mr. Brown’s fossils are, however, a very interesting discovery. 
They are not Molluscan, but Crustacean, being the remains of a 
phyllopodous animal that cannot be referred to any described genus. 
It is more nearly allied to Dithyrocaris than to Peltocaris, which is 
found in the same deposits. ‘One specimen is preserved, so as to 
exhibit the dorsal aspect of the whole carapace, which is in one piece, 
with the exception of the separate rostrum, as in Dithyrocaris. 
The round carapace, marked by concentric rings of growth, might 
be easily mistaken for a Discina. Several specimens are compressed 
laterally, and exhibit only the half of the carapace, having the ap- 
pearance of an Estheria, or even of a Modiolopsis.—H. W. 
MISCELUANEHOUS:

Tur vast Wealden formation at the back of the Isle of Wight, 
between Black Gang and Brooke, has long been celebrated for the 
great variety and wealth of its fossil remains. Numerous bones of 
Reptiles have been found in this formation near Brooke, principally 
belonging to that enormous lizard, the Iguanodon, which, with the 
Megalosaurus, Hyleosaurus, and other extinct monsters, passed their 
lives on the banks of this great Wealden river. Within the last few 
days, the Rev. W. Fox, of Brixton, near Brooke, well known among 
palzontologists for his labours in this branch of geology, has dis- 
covered in these beds a new reptile of the Dinosaurian family. The 
only parts of the skeleton wanting are the head and neck. The 
animal was above six feet long from the shoulder to the rump, and 
was furnished with a massive tail five feet long. The legs were 
about four feet in length, terminating in a broad, short foot. One 
of the most remarkable features of this strange reptile is the manner 
in which it is clothed in bony armour. Plates of bone from half an 
inch to four inches in diameter, and about half an inch thick, - 
covered its body, with the exception of its back, which was protected 
by a great bony shield. Another remarkable characteristic of this 
animal was a very curious process of spine-like bones, which ran 
along the body and the tail, some of which are fifteen inches long, 
and weigh seven pounds. ‘The remains of this extinct monster were 
examined last week by Prof. Owen, as well as the Wealden formation 
from which they were extracted; and we understand that, with 
reference to the extraordinary nature of the spine-like bones to 
which we have alluded, Prof. Owen is of opinion that the most 
appropriate name for this new Saurian would be Polacanthus.—
