onlyfrom a narrow stratigraphic interval of Tournaisian (early Osagean)agein the New Providence Shale Member of the Borden Formation in north--central Kentucky and southern Indiana,USA.The holotype of T.ver-neuilanum has not been studied since Milne-Edwards and Haime(1850,1851)originally described the external features of the genus based on thissingle specimen collected by Verneuil from the classic ButtonmoldKnob locality near Louisville,Kentucky.No other primary type materialis known to exist.Stumm's(1948:pl.17:25—29)description and illustra-  \ntions of transverse and longitudinal thin sections of a topotype andPickett's(1967:pl.1:12)discussion and illustration of a transverse thinsection of another topotype are the only means of presently evaluatingthe internal morphology of Trochophyllum.The paucity of detailed in-formation on morphological features needed for a modern appraisal ofthe systematic affinities of the genus,has led to disagreements betweencoral specialists concerning the relationships of this rare coral to othersimilar genera such as Permia Stuckenberg of Hudson and CrassiphyllumGrove(see Pickett 1967:7).The few species,exclusive of the type,assigned to Trochophyllum from Carboniferous rocks outside of the typearea,actually belong to other genera or need further study to determinetheir true affinities.  \nThe senior author became interested in Trcchophyllum during aninvestigation of small aulate solitary corals from the Carboniferous ofSpain and solicited the help of the junior author to compile informationon this peculiar coral.Because Trochophyllum is a part of the NorthAmerican Midcontinent (Southeastern Province)coral fauna,its systematicrelationships have an important bearing on the question of endemism ofthat fauna(see Sando et al.1977).This paper presents the results of adetailed joint study of the holotype and topotypes of the type speciesand provides our opinions concerning the systematic relationships andmorphogenesis of the genus.  \nAll figures in the text were drawn by the senior author,except wherenoted.  \nAcknowledgements.—We are deeply grateful to Dr.Pierre Semenoff-Tian--Chansky,Institut de
