identified the bones as belonging to the ancient homed sheep, 
the Keltic short-horn, the horse, and the dog. Many of the 
bones were split up, apparently for the purpose of extracting 
the marrow, and some bore the marks of the teeth of dogs. 
Some of the bones of the horse had been exposed to the 
action of fire ; the charcoal appeared chiefly to consist of 
burned stems of Ulex Europeus. 
No traces of weapons, or implements of stone or metal 
were met with, but Mr. Darbishire found a single fragment 
of bright red pottery, apparently of Roman manufacture, 
and from its shape probably being a portion of a small drink- 
ing cup. The absence of all bones of wild animals, birds, 
and fish, seemed to indicate a very low state of civilization. 
The author then proceeded to show from historical and 
legendary evidence, that the place where the shell deposit 
now exists was within historical times far removed from 
the shore, and quoted from Mr. Hall's paper before the 
Liverpool Geological Society, in 1864, as to the supposed 
ancient coast line, and submergence of the plain which once 
existed between the Great Ormes Head and Bangor, which 
is said to have taken place in the fourth century, when the 
lands and castle of Helig - ab - Glanawg were destroyed* 
The author also described Mr. Hall’s visit to the supposed 
ruins of this castle, marked “ Llys Helig ” on the ordnance 
map, only to be seen at very low tides, and submitted a 
diagram, copied from the plan of the walls and tower then 
taken ; he also gave the legend of the destruction of this 
castle, which is still told by the old Welsh people living 
near. The author concluded that when the refuse heap of' 
shells and bones was deposited, the coast line must have 
been somewhat the same as it is now, as patella, purpura, 
&c., being rock shells, could not have been found on a flat 
sandy coast; if, therefore, the plain was submerged in the 
fourth century, these shells must have been deposited 
subsequently; as besides the absence of rocks, the coast
