400 MR. H. BOLTON", F.R.S.E., ON [Feb., 1904. 



a bed of shale with nodules called the '' Soapstone Bed." 

 (W508, e coll. Wild, M.M.) 



Only one other specimen is known, from the Middle Coal 

 Measures of Medlock Park Bridge, Ashton-under-Lyne. 

 This is also in the Manchester Museum. 



Anthrapalaemorf Ether idgii. 



A specimen of the cephalothorax of this species was 

 found in the Lower Coal Measures of Cant Clough, near 

 Burnley, in 1884. It came into the writer's possession, by 

 whom it was verified at the British Museum. The specimen 

 was afterwards lost. 



Cyclus Scotti. 



The type specimen of this species was found by Mr. George 



Scott in shale over the Gannister coal at the Old Meadows 



Colliery, Bacup. It is now in the Manchester Museum. 



(L926, M.M.) 



Predivichia rotundata. 



A specimen of this species is in the Kay-Shuttleworth 

 collection (L2161) at the Manchester Museum. It was 

 obtained from Padiham, near Burnley, and whilst its horizon 

 is unknown the writer regards it as almost certainly in the 

 Lower Coal Measures, and from the horizon of the next 

 species, viz., the Mountain and Four Feet Mine. 



Architarbus subovalis. 



The type and only specimen of this species was described 

 by Dr. Henry Woodward in 1872, where it is stated that it 

 occurred in a clay-ironstone nodule from about four feet 

 above the *' four-feet mine," or "bone-coal" of Padiham. 



This description seems to indicate the horizon as above the 

 Mountain Four Feet, a supposition which is strengthened by 

 the fact that the horizon of the species is placed bj^ Mr. R. 

 Etheridge in the Lower Coal Measures. (Etheridge. Fossils 

 of the British Islands, PL I., p. 243.)
