REPORT OP THE STATE PALEONTOLOGIST 1902 1043 Still another characteristic pedicle valve from the same horizon has a width of 13 mm with a hight of 16 mm, but is very ventri- cose, appearing- proportionally higher. The plications are almost invisible and the sinus narrow, very shallow and rounded. This species is well represented in the upper Stromatopora bed of the Manlius limestone in the city quarry at Becraft. Its main distinguishing features are its subrhomboidal outline, shallow, narrow and rounded sinus, and obsolete or faint, broadly rounded plications. In the latter two features it differs materially from S. eriensis Grabau. Measurements of two characteristic pedicle valves from this bed give 1 2 width in mm . 12 12 hight in mm 9 10 A comparison of typical S. coralliensis with the types of S. modestus from Cumberland Md. shows a close rela- tionship, the latter differing chiefly in its extremely shallow sinus and faint fold, and in the total absence of plications. Specimens similar in most respects to typical S. corallin- e n s i s have been found in the Cumberland strata. Spirifer eriensis Grabau var. Geol. Soc. Am. Bui. 1S99. 11:3G6, pi. 21, fig. 2a-b A variety of this species is more common in the upper Stroma- topora bed at Becraft than S. corallinensis. It is char.
