158 UPPER, OR FLINTY CHALK. 



Tab. ix. fig. 1. This appears to be the remains of a winged seed, or 

 capsvde ; the black stain near it, is produced by carbonized wood. 



Localities. Chalk-pits near Lewes and Brighton. 



3. Unknown fossil bodies, resembling " the supposed juH of the larch." 

 Tab. ix. figs. 3. 6. 9. 10. 



These are of two kinds ; the first differs but httle from the bodies 

 already described as occurring in the chalk marl at Hamsey (vide 

 description of the chalk marl fossils) ; the other variety is more elongated, 

 its surface nearly smooth, and it is solid throughout. The constituent 

 substance of these fossils, is precisely of the same nature as the vertebree, 

 and other bones' of cartilaginous fishes, that occur in the chalk ; this 

 resemblance is so striking, that it is with considerable hesitation I have 

 noticed them in this place, being fully of opinion, that they may here- 

 after prove to be parts of fishes. 



Tab. ix. figs. 9, 10, are specimens of the imbricated variety, from 

 Steyning chalk-pits. The latter (fig. 10) resembles figs. F. G. PL V. of 

 Bur tin *, which are supposed by that author to be ''ft'uit, ou noyau de 

 fruit inconnu." 



fig. 3, represents a large example of the smooth kind, from 



the upper chalk, near Lewes ; a more perfect specimen lately discovered, 

 very much resembles in form the roe of a fish. 



Tab. ix. fig. 6. This specimen is of a very singular character, and is 

 the only known instance in which the "supposed juli" have been dis- 

 covered in connexion with other remains. The substance represented 

 at the base of the drawing, possesses the character of bone, but is too 

 much injured to admit of its original nature being ascertained. The 

 mutilated remains of three of the " supposed juh" are imbedded in the 

 chalk near it ; their relation to the substance in question cannot be 

 doubted, but at present the subject is involved in obscurity, and no 

 accurate opinion can be formed of their real nature and origin. 

 Localities. Chalk-pits near Lewes, Brighton, and Steyning.
