274 A. R. Horwood—Transition-bed and Crinoidal Limestone. 
? Fish-teeth._—Mr. Charles Upton found amongst the micro-organisms of the 
Upper Coral-Bed ( Zrwel/ei-hemera) a number of minute teeth not unlike those from 
the Rheetic which are generally called ‘‘Sawrichthys acuminatus’’, only much smaller. 
Also he obtained a minute round Lepidotus-like tooth. 
? Fish-remains in the Scissum-Beds.—Brodie, writing of the beds at Leckhampton 
Hill (Quart. Journ. Geol. Soc., vol. vii, 1851, pp. 208-12), which are now called the 
Scissum-Beds, observes: ‘‘ Bones, scales, Coprolites and teeth of Fish are dispersed 
throughout the mass, and may be most readily distinguished on the surface.” 
At Crickley Hill the Scissum-Beds reveal on their weathered surfaces, mixed up 
with the sand-grains and shell-debris, innumerable black particles, which prove to be 
minute phosphatic bodies. ‘hese may be the objects to which Brodie refers, but it 
is impossible to identify them. 
Tue Inrerior-OoLire VERIEBRATES OF NO VALUE FOR THE PURPOSES 
OF MINUTE ZONING. 
From the above list it will be observed that the fish-teeth called 
Strophodus are commonest in the Top-Beds (and especially in the 
Clypeus-Grit) ; the Reptilian remains in the ‘ Intervening-Beds” ; 
while the Freestone Series (except at Huddingknoll, near Painswick, 
where Strophodus teeth are very common) contains very few verte- 
brate-remains indeed. The Upper Coral-Bed has yielded a few, but 
unfortunately indeterminate, teeth, although probably piscine. 
Except, then, that the flat Strophodus teeth predominate in the 
Top-Beds, the little acuminate ? fish-teeth in the Upper Coral-Bed, 
and the reptilian remains in the Intervening-Beds, the Inferior-Oolite 
vertebrates afford little assistance in subdividing the series and are 
useless for minute zoning purposes. 
VII.—Nore oN A FURTHER EXTENSION OF THE ‘ TRANSITION-BED’ AND 
Crinormat Limestone Banp In THE Mippue Liss or LEercestERsHIReE. 
By A. R. Horwoop, Leicester Museum. s 
LLUSION has been made in a previous paper’ to the crinoidal 
limestone band and Transition-bed at Billesdon Coplow, and to 
the existence of the former at Tilton Hill near Lowesby Station. At 
the latter place, though the Transition-bed is not exposed in situ, the 
position of the crinoidal limestone bed (after making full allowance 
for Drift deposits), is low enough, with beds normally horizontal or 
with a slight easterly dip, to adduce without any doubt the extension 
of the Transition-bed above it at this point. Thus the crinoidal 
limestone band had been traced at three points —Tilton (vide 
Wilson, ibid.),? Billesdon Coplow, Tilton Hill—in the southern portion 
of the exposed area of the Rock-bed in Leicestershire, up to the time 
when the second paper, contributed by the author dealing with this 
bed in Leicestershire, was written. That is to say, it had only been 
found in the southern series of bold escarpments or spurs into which 
the district is divided. For the Twyford brook, running more or less 
west and east, divides the two series to which reference is directly 
made into a northern and a southern series, or if we include the 
Belvoir, Stathern, Eastwell, Holwell, and Waltham tract still more to 
the north, into three, with a central tract north of the Twyford brook.
