reefs), with fragments of drift-wood from some distant land, some- 

 times bored, or covered with, attached valves of oysters. Here, too, 

 the surface features have been variously modified, partly by faults, 

 but mostly by denudation, by which different layers of the oolitic 

 strata have been exposed, so as to modify the nature of the soils 

 according to the character of the rocks from which they have been 

 derived, for there is little evidence of foreign detrital matter (ex- 

 cept in one or two cases) being spread over the land or remaining in 

 this neighbourhood.

With the exception of one species, the individuals are all of small 

 size. Some are genuine Carboniferous species, and some genuine 

 Permain ; and they appear to be transitional from the Carboniferous 

 limestones to the Zechstein; all occurring in a well-determined 

 group of strata ; but some, characteristic elsewhere of one or other 

 of the above-mentioned formations, being found occasionally in the 

 same hand-specimen, as Productus longspinus and Strophalosia Cancrini. 

 This circumstance may be regarded as corroborative of the gradual 

 passage from the Carboniferous to the Permian, as held by Prof. 

 Geinitz for Nebraska, and by Dr. G. Stache for the southern Alps. 



II. — The Geology of the Burnlev Coal-field. 



THIS work, which is one of the recently published Memoirs of the 

 Geological Survey of England and Wales, includes a description 

 of the country around Clitheroe, Blackburn, Preston, Chorley, 

 Haslingden. and Todmorden, and explains Quarter-sheets 88 N.W., 

 89 N.E., and 92 S.W. of the One-inch Geological Map. It is by
