- <p><b><i>Brachycycloceras</i> (?) sp. D</b></p><p>Fig. 15D</p><p><b>Material examined</b></p><p>BELGIUM – <b>Liège</b> • 1 specimen; Chokier; <i>Homoceras beyrichianum</i> Zone (early Bashkirian); probably Beyrich 1845 Coll.; illustrated in Fig. 15D; MB.C.11126.2.</p><p><b>Description</b></p><p>Specimen MB.C.11126.2 is a small fragment of 16 mm length; it is partly covered with shell remains (Fig. 15D). It is an elongate tube with an apertural angle of only 7°. The specimen shows low annuli standing in distances of about 2 mm. The shell surface has an ornament with regularly spaced growth lines arranged in distances of 0.22– 0.15 mm.</p><p><b>Remarks</b></p><p>The small specimen cannot be connected with any of the other three specimens. Both the conch form, with its very small apical angle, and the sculpture, with very weakly developed annuli, indicate that the specimen may belong to the genus <i>Cryptocycloceras</i> Shimansky, 1968.</p>
