CYLINDRICODON.

cylindriques, mais elle paroit avoir cue des dents 
aigiies au bout de deux formes differentes.” This 
eminent physician and naturalist had the kindness 
to send me drawings of these fossils, and I perceived 
considerable resemblance between the teeth and 
some collected in Tilgate Forest, and which are 
figured tab. xv. fig. 3, 4. in my work on the fossils of 
that district. ( Vide PI. II. fig. 2, 3, 4. of this volume; 
fig. 3. is intended to explain the mode in which 
the edges of the crown of the teeth are worn from 
contact with tlie corresponding edges of their anta- 
gonists.) These specimens I submitted to the ex- 
amination of M. Cuvier, on his visit to this country 
in 1830, and that illustrious philosopher observed, 
that they were decidedly the teeth of an unknown 
reptile, but that their supposed identity with those 
of the Cylindricodon could not be determined from 
tlie figures of Dr. Jaeger. The subject has since been 
elucidated by M. Boue, the distinguished editor of 
the “ Journal de Geologie^'^ who favoured me with 
a visit soon after his return from Stutgard, where 
he had carefully examined tJie originals. This gen- 
tleman expressed his conviction that the teeth, which 
I shall now describe, must have belonged to the same 
kind of saurian ; their identification therefore rests 
upon his authority. These teeth are about an inch 
and a quarter in length, and commence with a sub- 
cylindrical shank, which gradually enlarges into a 
kind of shoulder, terminating in an obtuse angular 
apex, the margins of which are more or less worn, as 
if tlie teeth had been jilaced alternately so as to meet 
at their edges, as in Plate II. fig. 3. They are ob- 
scurely striated longitudinally, and have a thick coat
