was a bed of bluish clay about 7 iucbes thick, full of pebbles, 

 many of which were glacially facetted. This was evidently the 

 redistributed Boulder-clay derived from the brown Boulder-clay on 

 which it rested, which was only exposed about 6 inches in depth. 



Specimen 2 was taken from this brown Boulder-clay, but it was 

 only a surface specimen, much perforated by rootlet tubes. 



It will be seen from this description that the paucity of Fora- 

 minifera in specimens Nos. 1 and 2 is not surprising. 



Specimens Nos. 3 and 4 were taken from the blue clay (Formby 

 and Leasowe Marine Beds) a little west of the west end of the old 

 Wallasey Embankment, at a dejjth of 18 inches below the Superior 

 Peat and horizontally about 20 feet apart. Here were found 

 numei'ous specimens of Scrohicidaria piper ata,VQxi\GdiX as in life, with 

 both valves united but in a very chalky condition. This was a good 

 representative of the Scrohicularia Clay of the Formby and Leasowe 

 Marine Beds, and yielded Foraminifera in profusion. 



No. 5 is a specimen of brown Boulder-clay taken between Dove 

 Point and Hoylake at a greater depth than specimen No. 1 ; the 

 capping of redistributed blue clay and pebbles and Inferior Peat 

 and Forest Bed was more developed, and good-sized roots traversed 

 them, striking into the Boulder-clay below. This was an outlier 

 of the Inferior Peat-and-Forest Bed, the Superior Peat and Formby 

 and Leasowe Beds appearing on a higher level of the shore 

 immediately opposite the outlier. Mr. Wright's report shows that 

 notwithstanding the shallow depth at which the specimen of 

 Boulder-clay was taken it contained eleven species of Foraminifera. 

 The relations between these Glacial Foraminifera and the Post-Glacial 

 forms will be discussed later on. 



Report by Mr. Joseph Wright, F.G.S. 



No. 1, from between upper and lower peat beds, Leasowe Shore. 

 Weight of clay, 15-8 oz. troy. After washing, '8 oz. fine ; no coarse. 

 Clay very fine and containing a large quantity of vegetable matter. 

 Only one Foraminifer was obtained ; it was a weak specimen of 

 Trochammina inflata. 



No. 2. Brown Boulder-clay, under lower peat. Weight of clay, 

 18-4: oz. troy. After washing, 2-8 oz. fine ; "6 coarse. Most of the 

 stones more or less rounded, one of them showing faint strife. Clay 

 containing a large quantity of vegetable matter. Foraminifera very 

 rare, only three specimens of Polystomella striato-punctata. 



No. 3. Blue clay with Scrohicularia in sitii. Weight of clay, 

 17-8 oz. troy. After washing, '56 oz. fine ; '01 coarse. Fragments 

 of shells only. Clay containing a quantity of vegetable matter. 

 Foraminifera most abundant. 



FORAMINIFERA. 



* MiUolina seminulum (Linne). One specimen. 

 Cornuspira involvens, Rss. One specimen. 



* Troehamniina inflata (Montag.). Very common. (PI. V, Fig. 1.)
