LOWER CHALK—NORTH DORSET.

grouping now proposed. It was pointed out (Vol. I, p. 165) 
that the fauna of the nodule bed was that of the Eye Hill sand; 
the list there given is here repeated, with the addition of a few 
species since found by Mr. Scanes, and the omission of Exogyra 
conica and Terebratella pectita, which were obtained only from 
the sand below :— 
Ammonites [Schloenb.] varians. 
„ [ », ] Coupei. 
,, [Acanth.] Mantelli. 
Avicula gryphseoides. 
Pecten asper. . 
,, Galliennei. 
,, (Neithea) quadricostatus 
Ostrea canaliculata. 
Spondylus striatus ? 
Venus rotomagensis. 
Ehynchonella grasiana. 
Catopygus carinatus. 
Cottaldia Benettise. 
Discoidea subuculus. 
Holaster Isevis. 
Salenia petalifera. 
Micrabacia coronula. 
Siphonia tulipa (? derived) 
Porosphcera globular is. 
The next exposure is in a large quarry at Belchahvell, the base of 
which is not many feet above the Greensand, while the Melbourn 
Eock is visible at the top. The dip is eastward at about 15°, but, 
even allowing for this, there cannot be more than 140 feet of Lower 
Chalk here. Nothing like Chalk Marl is seen, the lowest part 
consisting of greyish marly chalk, rather soft, but blocky and not 
clearly bedded; this passes up into greyish-white chalk, which dries 
nearly white. No fossils were seen in situ, only a few in a fallen 
block of hard grey gritty chalk, which was unlike any tiling seen in 
the face of the pit. 
At Ibberton, 200 yards north of the church, there is a steep 
bank, which shows in one place a foot or two of grey chalk-marl 
with bluish mottlings. There can be but very little of this material, 
for Greensand is exposed in the hollow below the north-west side 
of the church, and to the south-west is a small pit in blocky chalk 
at a slightly higher level. 
The next section is at Woolland, in a pit on the slope of the hill, 
about 350 yards south-east of the church, where the following section 
was seen by Mr. Hill in 1893 : — 
ft. 
Soil and chalk rubble -------- 1 
Whitish blocky chalk, much fractured.3 
Soft silty and crumbly chalk, with occasional hard lumps ; 
where damp the colour is darkish grey, but it dries to a light 
grey - -.- - - - 2j 
Grey chalk consisting of very hard lumps with soft silty chalk 
between them, mottled with brown markings ; a few fossils 6 
The fossils found were Am. [Acanth.] rotomagensis ? (fragment), 
Pecten orbicularis, Rhynchonella grasiana, and Terebratula bipli¬ 
ca,ta. The hard lumps may be regarded as the incipient condition 
of a course of hard grey chalk, like those farther east. 
The next section is a pit near Moots Copse, half a mile north of 
Higher Anstey. Here. Mr. Hill saw : —
