Exposures cease before the red beds1 are reached. South ofHollowing Run no important outcrops appear until the axis of LittleMountain is passed, when the red Catskill beds, on the south side ofthe syncline, are seen dipping to the north. FORMATIONAL CORRELATION OF HOLLOWING RUN SECTION. By E. M. Kindle. The bearing of the detailed paleontological data given in the preced-ing pages on the correlation of the section may be briefly summed up. Zones 11 and 12 of the writers section represent a portion of No. 8of Whites section, which he called the Genesee shale. These bedshave been found to hold a fauna which is distinctively Nunda. Thephysical characteristics of the beds, which are hard and slaty insteadof fissile, confirm the evidence of the fossils and indicate that the lowerbeds of the sec
