•»* Lepisosleus Filto7ii, p. 252. Since the notice of this ichthyolite was 
written, Mr. Martin, of Pulborough, has discovered, in western Sussex, a 
splendid specimen of the liead and anterior part of the body, wltich he has, 
witli great liberality, submitted to my examination. By this interesting ex- 
ample we have been able to ascertain that the mouth was rounded, and the 
jaws were very strong and thick ; there are no teeth of detention, but those in 
the front of the mouth are more pointed and elongated than those which 
occupy the middle.* There are eleven or twelve teeth remaining in the lower 
and ten in the upper jaw. The skull is so much crushed, that neither its 
form, nor the situation of the orbits, can be determined. 
* Mr. Webster’s fig. 5. pi. vi. “ Geological Transactions,” second series, vol. ii., represents 
a portion of the jaw, with some of the teeth of the front row, of a young individual. Mr. W. 
mentions that he has found similar teeth in the Purbeck limestone.
