1862.] LISTER SHELLS IN DRIFT. 161

 Corhicula, is absent." 



The third exposure of this line of drift-deposit is a partially strati- 

 fied mound of sand and gravel, 88 yards long, 38 yards wide, and 

 about 2 yards in height, situated in Wobaston Big Meadow, about a 

 mile and a half north of Bushbury Junction. The long axis of this 

 moimd corresponds with the strike of the before-described beds, and 

 with the direction of the valley, which is due N. and S. This 

 deposit has not at present yielded me any shells nor specimens of 

 angular flints. The chief of its derived contents are the following : — - 

 pebbles of limestone, slate, quartzite, vein-quartz, black quartz, 

 veined lydian-stone, a fragment of syenite, and a small Silurian 

 coral {Cyathophylhim Loveni). The part cut into exhibits the fol- 

 lowing section : —

Two other patches of drift, lying at a somewhat higher level, occur 

 in this immediate neighbourhood, and are probably related by coin- 

 cidence of time and deposition. The first locality is that of Compton 

 Hollovray, in the parish of Tettenhall, where clay-deposits are seen 

 to fill up eroded hollows of the Keuper Sandstone on the hill-sides 

 west of the plain. These contaiu derived fossils from Liassic rocks, 

 similar to those inet with at Bushbury. A suite of them has been 

 collected by Henry Hill, Esq., of Dunstall. Many like remains were 

 found some years ago at Wightwick, another point at this higher level. 

 Here, however, the clay contains angular flints, as at Bushbury, and 

 the low hills are covered with scattered drift-pebbles. 



In drift-clay, at about the same level, near the Hospital in Wol- 

 verhampton, Liassic Oryphcece have been met with ; and fossils of 

 like age in a similar bed at the New Cemetery. I am indebted to 

 Mr. Henry Beckett, F.G.S., for some notes respecting this easterly 

 extension of the boulder-clay, as also for a notice of other exposures 

 at Penn, from two to three miles south of Wolverhampton. At Upper 

 Penn, the clay yielded pieces of wood and a broken tibia of Bos. I 

 am also informed by Mr. George E. Roberts of a considerable exten- 

 sion of these clays, vtdth sandy layers, westerly ; for they are well 

 exposed at Acleton, eight miles S.W. of Bushbury, and there abound 

 in Turritellce. A recent exposure in that district is at a spot half a 

 mile north of Badger Hall. 



In conclusion, I would call attention to the deep and wide- 

 stretching sand deposit described by Prof. Beete Jukes as lying in 

 immense quantities around West Bromwich and upon the district 

 east of Birmingham*. In the lower part of this sand, which in places
