HAMITES Gigas. 
TAB. DXCIIL— ^g. 2. 
Spec. Char. Largely ribbed ; inner side plain, 
flattish; ribs composed of six laterally ex- 
panded tubercles. 
A rather suddenly curved species : six blunt spines are 
united, three on a side, to form each oblique rib, which is 
nearly lost as it passes over the front ; the spines near the 
front are largest ; the section is rather square. 
We have to acknowledge our obligations to the Right 
Honourable Lord Greenock, whose anxiety to render a 
service to Geology has induced him to lend us this and 
several other rare subjects from the Greensand formation 
near Sandgate. 
u It occurred in the second or lower bed of Limestone, 
in its uppermost course of Rag and Clay above Seabrooke, 
between Sandgate and Hythe. Other specimens have been 
collected in the same stratum and bed, upon the Roughs 
west of Hythe, one of which is in Mr. Hill’s collection.” 
For these particulars I am obliged to my respected friend 
G. E. Smith, Esq. who is residing at Sandgate. 
We are informed that there are much more gigantic 
Hamites to be found in the rocks at the south-eastern part 
of the Isle of Wight : possibly they are of the same spe- 
cies ?
