4. Interbedded agillaceous limestone and marly clays, the lime 
stone in weathering crumbling readily into rounded frag- 
ments. Fossils well preserved. Among those found are: 
Epiaster elegans Shum., Holaster simplex Shum., Nautilus 
texanus Shum 40 
5. Blue shaly clays interbedded with brittle yellow limestone of 
more or less concretionary structure. There are three beds of 
this limestone which are persistent. 
5a. Upper or O. quadriplicata limestone, underlying No. 4 
and containing Ostrea quadriplicata Shum., Plicatula in- 
congrua Con., Pecten texanus Roem., Gryphxa pitcheri 
Mort. 
5b. Middle or G. tucumcarii limestone. This bed, which 
has a thickness of four feet, is separated from the last by 
about ten feet of blue shaly clay and is highly fossiliferous, 
containing: Schlcenbachia leonensis Con., .S'. peruviana 
von B., Gryphxa Pitcheri Mort., G. dilatata var tucumcarii 
Marcou, Cyprimeria crassa Mk., Ostrea subovata / Shum., 
Pecten texanus Roem., Terebratula wacoensis Roem., Trig- 
onia emoryi Con., Epiaster sp. ind., Turritella seriatim- 
granulata Roem., T. marnochii White, Cardium multistri- 
atum Con. 
5c. Lower bed. This bed is six feet below 5b, and in places 
separates into thinner bands of limestone and shale, while 
at others it appears as a compact bed of limestone. The 
fossils contained in it are neither numerous nor very well 
preserved. The following were collected: Pecten texanus 
Roem., Schlcenbachia leonensis Con., Lima wacoensis Roem.,
