ON COLLECTING FOSSIL ECHINODERMATA. 335 
There is a matchless suite of fossil Echinidz in the 
British Museum, which has been arranged and named by 
Mr. 8. P. Woopwarp, and is now the most instructive and 
interesting collection extant. It contains examples of the 
following genera, viz., Ananchytes, Echinocorys, Echino- 
_lampas, Holaster, Galerites, Cidaris, Diadema, Acrosalenia, 
Glypticus, Disaster, Pygurus, Clypeaster, Scutella, Salmasis, 
Kchinocyanus, &c. There is also a good series of echinital 
spines.
