Section of the Clee Hills at Oreton. 



These Millstone Grits are non-fossiliferous ; but the mineralogist may- 

 detect in their conglomerated structure many pebbles of a high class, 

 jaspers and cornelians of pure quality being often met with. These 

 beds lead up to the Mountain Limestone, which contains a fine series of 

 organic remains, such as palatal teeth of the Cestraciont fishes. Peta- 

 lodus Hastingsii and Psammodus porosus are abundant ; yet, although 

 fragments of their jaws are not uncommon, I have only met with one 

 specimen having the teeth in their true position. Shells and corals are 

 plentiful, but limited in species, only the most typical being found. The 

 Crinoids are well represented in the fragmentalia — one bed lying low 

 down upon the yellow sandstone is little else than a mass of detached 

 ossicula and pelvic plates, which are nearly all referable to one genus, 

 Cyathocrinus. 



The ridge is boldly quarried ; in two cases the excavations pass 

 through its back-bone of Mountain Limestone to the underlying yellow 

 sandstones, and these spots I would especially recommend to the 

 geologist who wishes to work out the animal contents of those particular 

 strata. The rugged masses that are broken up for the kilns are weari- 

 some to work and nearly devoid of fossils. The easternmost quarry on 

 the ridge, where the beds are most vertical in their dip, I would also 

 specially recommend; for in the yellow sandstone there exposed I have 

 recently obtained some interesting remains of Pterichthys, consisting of 

 plates of the back and, what are even more easy to make out, their 

 curiously-shaped tails. These are new to English beds. With these 

 I have found scales of H'oloj^ti/chms noMlisimus, S. giganteus, 

 and a detached jaw-tooth of H, Eillertii (?) The fine head of 

 Pterichthys, a new species, according to Sir P. Egerton, discovered 

 by Mr. Baxter, of Worcester, was obtained from a quarry at Farlow, a
