(vi, v) Garantiana Beds. — No rock of garantiancB hemera 

 recurs in the neighbourhood of Broadwindsor, as is shown by the 

 section at Conegar Hill (p. 153), where limestone of probably 

 schlcenbaclii date rests directly on the Murcliisonce Beds. At 

 Misterton Liineworks, the Lecker-Bridge section (South Perrott), 

 and Ten-Acres-Field Quarry, however, occurs rock very barren of 

 fossils, but similar to that of f/arantiance hemera at Green- Hill 

 Quarry, near Innsacre Farm, Shipton Gorge (Dorset) — that is, 

 somewhat soft limestone with numerous brownish oolite-granules- 

 At the Lecker-Bridge section there is below the main layer rubbly 

 limestone (0 to -i inches thick) ; but at the Hill- Farm section, 

 South Perrott (5) there is no rock at all of garantiance hemera. 



At Slade's Quarry, North Perrott, the Garantiana Beds have 

 ' expanded,' are very fossiliferous. and in addition to the quantity 

 of rich yellowish-brown ochreous matter associated with the lowest 

 layer (c) (see p. 164), their top marly layer is rich reddish-brown, 

 owing to the presence of oxidized iron-pyrites such as one is 

 accustomed to meet with at this horizon in the Burton-Bradstock- 

 Beaminster district. At the Haselbury-Mill Quarry a similar 

 ferruginous marly layer overlies a 6-inch bed of limestone, the lithic 

 structure of which calls to mind the Marl-Bed and subjacent lime- 

 stone of the neighbourhood of Bradford Abbas. 



North- west of Crewkerne, at the quarry in Hinton Park 

 (20) the rock of ffarantiance hemera consists of some r 4 feet 

 6 inches of massive rich brown, ferruginous limestone, overlying a 

 hard somewhat conglomeratic limestone (? 18 inches thick) full 

 of fossils, including Patoccras anmtlaium (A. d'Orbigny) — the 

 whole recalling the Hadspen Stone of the Castle-Cary district. 3 



Top Limestones. 3 — Top Limestones, similar to those of the 

 neighbourhood of Beaininster and Broad Windsor, extend into the 

 Crewkerne district, and maintain their similarity throughout it 

 with the exception of the neighbourhood of Haselbury Mill. In 

 this direction the Top Limestones have ' attenuated," their con- 

 stituent beds are better separated one from the other, and, at the 

 Haselbury-Mill Quarry, include a very interesting Sponge-Bed, 

 very similar in appearance to the well-known one at Shipton Gorge 

 (Dorset).;* 



Indications of the Zicfzacj Bed, similar to its equivalent at 

 Broad windsor and elsewhere in the Burton-Bradstoek-Broadwindsor 

 district, have been found in an opening near Slade's Quarry, 



1 I have seen a Kpeeiinen of Pleurotomaria, stated to have come from 

 Dinnington, in a matrix which at once called to mind that of the Irony 3>o<l 

 of Louse Hill, near Sherborne (Dorset). It may be that rock of blaydeni date 

 occurs sporadically in ' pockets ' in this neighbourhood, as is also probably 

 the case at Dundry Hill, near Bristol.
