two bands of conglomerate, which include between them the middle 

 member or Waverly proper. 



The upper Waverly, with its 100-150 feet, has been rather less 

 studied than either of the other divisions. Near the top it is charac- 

 terized by Prodiictiis scmiretiailaiiis, Spirifer stratiformis, Phillipsia me- 

 ra?necejisis, Nautilus sp, Crcnipecten, sp. n. Hemipronites is also very 

 abundant. 



The upper conglomerate, or congl. II. is itself often fossiliferous- 

 with the species characteristic of the shale below and especially Spir- 

 fer 7vinchelli. Allorisma winchelli, A. ventricosa, Sanguinolites obliquus, 

 Prothynis meeki, Edinoiiiia, etc., are the determinative forms for the 

 shale. The free-stone which lies below this shale is full of fossils. 

 Spirifer carteri, Crenipecten winchelli, Phillipsia shumardi, Rhynchonella 

 cooperi and R. contnicta are characteristic of this zone. After an in- 

 terval of shale, sometimes with Allorisma winchelli, but generally bar- 

 ren, we reach congl. IT, which varies from a narrow belt of sandy free- 

 stone to 10 feet of coarse sand and conglomerate. A few feet below 

 this is one of the most characteristic layers of the whole formation, 

 abounding in Palosoneilo concentrica, and P. aftenuata, SaTigui?iolite^ 

 unioniformis, Streblopteria media, Bellerophou lincatus, B. galericulatus^ 

 etc., etc. The same fauna may be found for 30 feet below, but 40-50- 

 feet below is a zone with quite a different habitus, containing Ryncho- 

 nella sapp/w, Leiopteria ortoni, Crenipecten tumidus. 



Near the same horizon, probably below it, but exposed further 

 west and not yet certainly located vertically, is a zone with Spirifer 

 maj'ionensis, which species is also abundant in limestone nodules some 

 15-20 feet lower along with a peculiar fauna of considerable individu- 

 ality, at Moot's run. 



Through the kindness of Mr. E. S. Clarke, a system of levels was 

 run from Granville to exposures eastward from Newark, correcting the 

 barometric work of last year. The conglomerate I. being the most, 

 available base line, the levels refer to the top of this stratum, which 

 is exposed along "the avenue" leading to the buildings of Denison. 

 University. Along a line bearing S. 68° E., for 385 miles, this con- 

 glomerate dips 79.35 feet, from this point to the south Newark quarry,, 

 a distance of 4.44 miles S. 79° E. the dip is 48.74 ft. A portion of 

 the difference in inclination is due to the increased thickness of the 

 conglomerate to the eastward, but the influence of the Clay Lick arch 

 is also beginning to be felt. In our last report the mistake was made
