insculpta layer, must have come from about the horizon excellent interior of ventral valve. Steph. ma planumtina also occurs here From 23 ft blm. the insculpta larger than Rhynchella similata is its chief fossil borer. 3y greater heads: excellent. 35 feet blm top of W. insculpta Stephennema delarumtina rare but loose, as far down as top of dense lime such 81 ft blm in top of H. insculpta bed. While this suggests Rich- mound age, the great thickness of the Lynn Rch mound in that case is against it. Collected Sargra 0-5 ft above this level = 81-76 ft blm W. insculpta 5 of Rhynch. dentatum from just above dense lime lay limestone. Also Septum ridiculus. This is probably identical with the Rhe. dentatum layer at the Browns Pond section in same part of Redcliffe about 2 mi, 1 mi E of Lynn co. line. The dense blue limestone con- tains very few fossils. The first specimens large enough to be and called lynx occur 14 1/2 ft blm top of massive blue dense limestone. 1 Rhynchostea dentatum appeared to occur (lose) near this point this part of section (14 ft down.) The top of lynx lowest ones are 14 ft below dense. These lynx bed layers appear to be very much decreasing down for 15 ft when exposure ends.
