BOULDER-CLAY AT BRIDLINGTON QUAY. Path 
has been found includes fourteen stations in the North Atlantic, the 
most northerly being about lat. 60° N.” 
Puluvinulina Karsteni is a Shetland form, and is figured in 
Mr. H. B. Brady’s paper on the ‘‘Rhizopodal Fauna of the 
Shetlands”’*. 
Several species of Nonionina occur in the glacial clays, so that the 
appearance of a species doubtfully named UN. orbicularis raises no 
difficulty regarding the general character of the group. 
The Foraminifera, as well as the Ostracoda derived from the 
new material I have examined, when compared with the Scotch 
fossils and studied together, give considerable ground for the sup- 
position that these ‘“‘ shelly patches” in the Bridlington Boulder-clay 
belong very closely to the same period of the glacial epoch as that 
represented by the fossiliferous clays of the coast of Scotland.

Discussion. 
Dr. J. Gwyn Jurrreys believed, from a personal inspection, that 
this was a remanré deposit. He had supplied Prof. Phillips with a list 
of the Bridlington shells for the second and posthumous edition of 
his ‘Geology of Yorkshire.’ The present list showed that the 
total number of species and varieties amounted to 74+, of which 33 
were purely arctic forms, 1 a deep-water form (480 to 560 fms.), 
2 American forms, 33 shallow-water forms (under 100 fms.), and 
there were 5 perfectly new species. Besides the peculiarly arctic 
species, 20 of the littoral species are also arctic, making the total 
number of the latter 61, or nearly 87 per cent. of the whole. 
Similar purely arctic forms had been lately found in deposits near 
Glasgow. These shells were much more arctic in character than 
those of Moel Tryfaen, which might be referred to a Celtic area of 
distribution. 
Prof. T. M‘K. Hueuss said that many years ago he had found, 
with Mr. Lyell, in Dimlington cliff, a lenticular bed of sand with 
Nucula Cobboldie, Astarte compressa, and other shells, some of the 
bivalves with the shells in contact. He thought it more probable 
that the shelly patches were pushed up by the grounding of ice- 
bergs and shore-ice from the sea-bottom close by, than that they
