BOULDER-CLAY AT BRIDLINGTON QUAY. 325 
discovered in gatherings of glacial clay from Montreal and Saco, which 
were sent to the writer of this note by Principal Dawson. 
Cytheridea elongata ‘is common enough as a recent species all 
around these islands ” and lives in the Gulf of St. Lawrence also, so 
that it is not surprising to find it in a glacial deposit*. 
The general statement made by Mr. Lamplugh in his paper re- 
specting the fauna of the shelly patches in the Boulder-clay that 
(with the exception of a doubtful Rissoa) no “species are found save 
such as might form part of the same life-group,” accurately repre- 
sents the state of the case with respect to the Ostracoda. 
FoRAMINIFERA. 
In the Monograph of the “‘ Foraminifera of the Crag,” by Prof. 
T. R. Jones, W. K. Parker, and H. B. Brady+, the following 
passage occurs :—‘‘ Some Foraminifera collected by Mr. H. C. Sorby, 
F.R.S., from the Bridlington Crag some years ago, and kindly placed 
at our disposal, have to be noticed. These comprise Cornuspira, 
Miliola, Lagena, Dentalina, Cristellaria, Polymorphina, Cassidulina, 
Truncatulina, Polystomella, and Nonionwna, and are the most con- 
spicuous of a probably more extensive fauna, nearly allied to that of 
the Suffolk Crag.” 
As Mr. H. B. Brady points out to me, however, much more is 
known of the distribution of the northern forms than when this 
paragraph was written; and, of the 18 Bridlington species described 
in the monograph, all save one have been discovered in the North 
Atlantic, and 14 of them in the Arctic seas. 
When in connexion with this fact their association with Arctic 
Mollusca is considered, the application to them of the term “‘ Crag’ 
becomes more than questionable. 
The new material has yielded 16 species, with two varieties of 
species. 
Of these 16 species, 8 are catalogued as from Bridlington in the 
monograph ; and the whole of these occur in the Scotch glacial clays. 
Of the remaining 8, 5 are Scotch glacial fossils; while 3 species 
and 2 varieties, although catalogued as glacial fossils for the first 
time, are not improbable members of the same group, so far as 
climatic conditions are concerned. 
The following is the list of Foraminifera ; the number of specimens 
found was far greater than of the Ostracoda :— 
Genus Brrocutina, D’Orbigny. 
B. ringens, Lamk. Moderately common. 
Genus Casstputtna, D’Orb. 
C. laevigata, D’Orb. Rare.
