Five miles north of High Falls the 200 foot of Harrangunk has thinned to about 10 feet (but maybe) We see here therefore a decidedly increased slope of the old sea floor and a much flatter slope from Crompton to Albany. South from High Falls to Pottersville the slope is also slight for the increased thickness is not so great as between High Falls and 5 miles to the north. In the Otisville Harrangunk Reedmann has many sparse Enigpuni, many but 1 millimeter in length. Also larger size and few segments lengths of 5 feet are indicated. These are Stylurus. Bechus nectonatus is only in that the larger legs are in front with the shorter one in the rear.
