The fauna, as a whole, is fairly uniformly distributed in the 

 limestone, but one or two horizons occur which are marked by 

 special forms. In the basal conglomerate occurs a small species of 

 Favosites (F. hisitigeri), which appears to be especially abundant 

 at this horizon. A short distance from the base we. meet with a
