The above strata are seen just to the east of Pittenweem. 

 Beneath them are about 450 feet of measures with no marine beds. 

 In these measures there are more shale and fireclay than sandstone, 

 though the alternations of argillaceous with arenaceous strata are 

 numberless. Nearly all the shales are charged with ironstone bands 

 and nodules, and some of them are nighly bituminous. Ten thin 

 coals occur in this part of the section, most of which rest on fireclay 

 with Stigmarian rootlets. 



Plant-remains are very generally distributed throughout, though 

 the species are few as before. The remains of Stigmaria are 

 common, not only in the fireclays underlying the coals, but in other 

 beds. Lepidodendron and Lepidophyllum are found in many of the 

 strata, and Sphenopteris affinis and Cyclopteris Jiahellata are not rare 

 in a fragmentary state ; the latter species has not been found much 

 above the line of 2250 feet. There are also the teeth and scales of 

 small Ganoids at various horizons, often associated with plants ; and 

 the carapaces of Ostracod crustaceans are very plentiful in some of 

 the black shales and ironstones. Leperditia Okeni, var. scotohurdi- 

 galensis, is the most prevalent ; the other species are Beyrichia 

 subarcuata, Cythere superha, and Carhonia subula. 



Below the above measures, and at a depth of over 2800 feet, 

 there comes into section a bed of shale, about ten feet thick, with 

 two bands of calcareous ironstone. This deposit contains the fol- 

 lowing marine species : —
