232 Notice of Orthoceras anmddris and striata. 



its chambers and 

 siphunculus nearly 

 perfect. 



Its general ap- 

 pearance somewhat 

 resembles a trans- 

 versely fluted co- 

 lumn, with an ele- 

 vated ring corre- 

 sponding to each septum. It is surrounded, also, by a number 

 of beautifully waved lines, which, on the rings, form angular 

 projections. The specimens I have yet seen, from this place, 

 are quite straight, and present, perhaps, three or four varieties. 



Some specimens {Jig, 67.) have elevated rings, with waved 

 lines around them; others (/^. 68.) have slight depressions 

 with longitudinal straight lines. The larger kind are fre- 

 quently from 2 in. to 3 in. in diameter, and upwards of 1 ft. 

 in length ; but the smaller specimens are generally most perfect 

 and beautiful. 



The shaft from which the new trilobite was obtained, and 

 from which the most perfect orthoceratites may also be pro- 

 cured, is at this time filled with water ; and the open-work or 

 out-crop of this stratum being subject to decomposition, from 

 atmospheric influence, very few specimens of value can at this 

 time be obtained. 



The upper, or Dudley, stratum, which also extends superfi- 

 cially to this place, carries with it all the train of fossils which 

 are found at Dudley and Walsall ; but, in the lower stratum, 

 I have not yet heard of any others than the large trilobite and 

 orthoceratites having been found. 



Since I wrote the above, I have been informed, by Mr. 

 Miller of Bristol, that he has in his possession two specimens 

 of trilobites, discovered in the transition limestone at Ledbury,
