In elaborating the genus Lunulicardium which is so exten- sively represented in the Intumescens zone of western New York I have secured some very delicate barite replacements of the valves of Lun. clymeniae which retain the protegulum and give some indications of the value of torsion of the shell as an ontogenic character and it has become possible also to make some observations on the probable phylogenic significance of the same feature. Lunulicardium has been commonly re- garded as a bivalve with a long and wide byssal opening. Beus- hausen has shown that the beaks in a certain subdivision of the.
