Description and discussion The association of the aptychus form-genus Spinaptychus Trauth with thegenus Texanites was discussed on an earlier occasion by the authors (Kennedy& Klinger 1972: 394-399; Klinger 1972: 105-109). Two texanitine specimens,one of them referred tentatively to Texanites soutoni, were available to theauthors, and it was concluded that the association of Spinaptychus with Texa-nites is real. Since then, three more aptychi have been found, either in bodychambers of, or associated with, texanitids, thus further establishing the rela-tionship between Spinaptychus and Texanitinae.
