414 A. R. Horwood—Upper Trias, Leicestershire. 
and not referable to that genus, and later he said it came from the 
Rheetic. ; 
Red Marl. 
Voltzia sp.—Mr. Harrison records the fact that the only fossil he 
found in the Red Marl was ‘‘ casts of the spreading leaves” of Voltzva. 
It is probable that careful search, as suggested by Browne, would 
reveal the occurrence of teeth, ete., of sharks in the skerries and 
coarse sandstones. The late Mr. G. Lomas found Estheria minuta 
var. brodieana in the Red Marl at Oxton, near Liverpool. Near 
Newark scales of Gyrolepis associated with salt pseudomorphs have 
been found in the grey beds. In some dolomitic skerries there are 
obscure traces of organisms which might be the casts of mollusca. 
In marls and clays containing pyrites or allied decomposing agents 
where sulphuric acid is formed fossils may be dissolved as pointed out 
by P. M. Duncan. The high proportion of sulphuric acid in the 
Gypsiferous Marls is in itself a reason for their apparently (I would 
emphasize this word, and endeavour to stimulate research for traces 
of life at this horizon, rather than discourage it, as is usually the 
practice) unfossiliferous nature. 
Tea-green Maris. 
It is due to the last cause that probably the occurrence of fossils in 
the T'ea-green Marls is little known. But though they are not 
abundant they occur in some variety. They have been found in the 
West of England and at other places. ; 
In Leicestershire at all of the three principal exposures, Gipsy 
Lane, Spinney Hills, and Glen Parva, scales of fossil fish have been 
discovered. ‘They belong apparently to a Semionotoid type. They 
were especially abundant at Spinney Hills, where the Tea-green Marls 
were green and blue and buff in colour. With them occur Hstheria 
minuta (Alberti) in some quantity. There are obscure remains of 
what are probably plants and apparently casts of shells. 
Mr. Harrison records that he found an insect wing, but he said it 
perished immediately, and it is more than probable that it was 
Estheria. At the same time the lithic structure is similar to the 
insect-beds of the Rheetic and Upper Lias, so that, especially as insect 
remains occur in the Rheetic, not far above the bone-bed, it is less 
improbable. At the Spinney Hills Colobodus frequens (Dames) was 
found and teeth and scales of a paleoniscid fish. 
At Glen Parva there are, as at Gipsy Lane, regular bands of fish- 
scales, and, in addition to these, Orbiculovdea townshend, Davidson, 
and annelid tracks have been found by Mr. A. J.S. Cannon. ‘This 
Brachiopod is common to the Rheetic also. 
The continuity of the fauna is, moreover, carried on by the 
occurrence of true Rheetic fossils in the Sully Beds below the Bone- 
bed, represented in the West of England and Wales. 
Rhetie. 
In the notes which follow the localities given are preceded by 
a number indicating the horizon at which the specimens were found, 
which is correlated with the Pylle Hill sequence as defined by Wilson.
