A4 Reports and Proceedings : 
Badgers have been found at the Wookey Hole Hyena-den. The 
Herbivora are much more numerous in the caverns than the Car- 
nivores. Elephas antiquus is associated with KH. primigenius in 
Banwell and Bleadon Caverns, with Rhinoceros hemitechus and Hip- 
popotamus major on Durdham Down, and has been found also on 
the banks of the Exe. The Mammoth is common alike in the caves 
and the river-deposits. Rhinoceros tichorhinus and R. hemitechus 
have been obtained from Wookey Hole. The remains of Horse are 
very generally met with: the caves of Bleadon and Durdham 
Down alone have yielded Hippopotamus major. The Wild Boar 
(Sus serofa) has been obtained from both caves and river-gravels. 
The Cervide comprise the Irish Elk, Red-deer, Roe-deer, and Rein- 
deer. The Bison (Aurochs, Bison priscus), a second smaller variety 
or species (B. minor), and a third and yet smaller one, and the great 
Urus (Bos primigenius), prove that the Bovide were abundant in 
the Newer Pliocene times in the district referred to. The Rodentia 
are represented by the Rabbit, Hare, and three species of Vole (Ar- 
vicola agrestis, A. pratensis, and A. amphibia). The discovery of 
the Marmot (Spermophilus erythrogenoides, Falc.), we owe to the 
energy of Dr. Falconer. 
But the last and most important addition to the fauna of the dis- 
trict in those early times is that of Man. The implements of flint, 
chert, and bone found in the Wookey Hole Hyena-den, prove him to 
have been a contemporary of the Cave-bear, Cave-tiger, Mammoth, 
and two extinct species of Rhinoceros, and to have belonged as truly 
to the Cave-fauna as any of the extant Mammalia. 
On somm New Points In THE Structure or Patmcutnus. By W. H. Batty, 
Ksq., F.L.S., F.G.S. 
HE author stated that, having had occasion, for the purpose of 
comparison, to examine the fine series of fossils belonging to 
the genus Palechinus in the well-known collection of Sir Richard 
Griffith, Bart., the eminent geologist, and Chief of the Valuation- 
department in Dublin, he was fortunate enough to find amongst 
these beautiful Hchint of the Carboniferous Limestone one of the 
species Palechinus elegans, from the lower beds of the limestone 
at Hook Point, Co. Wexford, which was sufficiently perfect to en- 
able him to make out the arrangement of the plates composing the 
apical disk—an important part of the test or shell not hitherto de- 
scribed. He found that the principal plates were the same in number 
and position as in the Secondary and more recent forms of Eehini, 
although differing in their proportions; there being five genital 
plates, one of which, rather larger than the rest, was probably the 
‘madreporiform plate, and five ocular plates; these being much 
larger than usual in more recent forms, and the genital shorter in 
proportion to their breadth. In addition to these, there were inner 
circles of ten sur-anal and a similar number of anal plates. 
The great peculiarity and most remarkable difference between 
this part of the Palechinus and that of the recent Echinide was 
described as consisting of a double perforation of the ocular plates, 
and triple perforation of the genital plates. 4
