120 THE CRETACEOUS- ROCKS OF BRITAIN. 
Mr. Davidson gives a table on p. 115 showing the Brachiopddit 
found by Mr. Wiest in each of his beds, from which it appears that 
the same species were obtained from Beds II. and III., except that 
Terebratella Menardi was only found in the latter. The Rhyn- 
chonella Cuvieri of this list is what he subsequently described as 
Rhynch. Wiesti. 
The commonest fossils in the bottom layer or “ Scaphites bed ’’ 
are Am. [Schioenbachia] varians, Am. [Schl.] Coupei, Am. [ Acantho - 
ceras] rotomagensis, Am. [Acanthi] Mantelli, Scaphites cequalis , 
Turrilites Wiesti , Nautilus expansus, N. Icevigatus , Cucullcea maille- 
ana, and Calerites castanea. A complete list of the fossils found 
at Chard and Chardstock will be found at the end of the chapter. 
The quarries at Chardstock, three miles south-west of Chard, 
are now abandoned and overgrown. There is, however, a small 
exposure in a quarry half a mile north of Tytherleigh and east 
of the old quarries. 
The higher part of the Lower Chalk was only seen in two places, 
and in each case it was overlain by grey marl, which may be the 
Belemnite marl or a band of marl at a lower horizon, like that at 
Lulworth (see p. 98.) 
The first locality was a quarry about two miles W.S.W. of Crew- 
kerne, on the hill south-west of Combe Farm* As seen in 1893, 
this showed : —

and seen for - - - - - - t - - -12

There is a dip of about 5° to the south, and the surface at the top 
of the quarry is about 80 feet above the base of the Chalk to the east¬ 
ward. In the blocky chalk w T ere found Pecten Beaveri , Pecten 
orbicularis, Ostrea vesicularis, Inoceramus sp., and Sponge remains. 
No flints were seen. 
a. Whitish chalk. b. Soft grey marl. 
The only other exposure of this marl met with in the district was 
in a quarry over two miles north-w est of Chard,called Combe Wood 
Quarry. This is a remarkable section, for the beds dip eastward 
at about 12°, as shown in Fig. 29i
