THE FISHES OF LEICESTERSHIRE AND RUTLAND. 
zone), Plungar (see “ Greol. South-West Part of Lincolnshire, etc.,” ‘Mem. Geol. 
Survey,’ p. 125). 
Teeth appear to have been found by Mr. Harrison* * * § in the Upper Keuper 
Sandstone, in a cutting near the Dane Hills, but none of these are in the 
Museum. 
Hyhodus crassus, Agassiz. 
In Rutland. — Remains of this have hitherto been attributed to the Inferior 
Oolite, Braunston, Oakham, but Mr. A. S. Woodward, at p. 301 ‘ Catalogue of 
Fossil Fishes,’ writes: — “47,144. Type specimen of Hyhodus crassus, Agassiz, 
described and figured, tom. cit, p. 47, pi. x., fig. 23, said to have been obtained 
from the Inferior Oolite of Braunston, Oakham ; the locality cannot be accurate, 
and is given by Agassiz as Rodmore Pits, near Towcester.” 
Hyhodus cloacinus, Quenstedt. 
To Mr. W. J. Harrison appears to belong the honour of having first 
found some teeth and fragments of teeth and portions of two or more fin-spines 
in the Rhsetic bone-bed. Spinney Hills, identical with those assigned by Quenstedt 
to H. cloacinus, hitherto described only from the Rhaetics of Wurtemberg ; 
and the Museum has lately acquired a number of teeth (not quite so fine) 
from Mr. Quilter, found by him in the same place, and fully described by 
Mr. A. S. Woodward.! 
Hyhodus minor, Agassiz. 
The Museum possesses a nice tooth of this small Shark, found by Mr. Harrison 
in the Rhsetic bone-beds. Spinney Hills,! and has lately acquired quite a quantity 
of teeth, collected by Mr. H. E. Quilter from the same place, and described by 
Mr. A. S. Woodward, § who thinks it is quite possible that the teeth now 
ssigned to Hyhodus minor will eventually prove to belong to the Shark 
whose dorsal fin-spines, found in the Rhaetics, are known as “ Nemacanthus,” 
—and in this case the small fragment mentioned by him at p. 19 would be 
assigned to the present species, as would also portions of three or four spines 
recorded by Mr. Harrison under the names of Nemacanthus monilifer and 
Hyhodus minor, % and now in the Museum. 
The Museum of Practical Geology, Jermyn St., London, possesses a spine 
{Nemacanthus monilifer) from the Rhaetics of Wigston.
