MATERIAL. — Four specimens (recovered with the hydrogen peroxide method); two specimens (recovered with the acetic acid method). DESCRIPTION Multi-segmented Nassellaria (with probably six segments),spindle-shaped in outline.The poreless cephalis bears a small and curved apical horn. Post-cephalic segments increase regularly in width and height until a median segment; strictures between segments welldeveloped.Thorax,abdomen and post-abdominal segments possess circular pores, apparently, quincuncially arranged. Distal segments inverted conical in shape. REMARKS Besides its similarity to Stichomitra carnegiense (Campbell & Clark, 1944) , the poor preservation of the recovered specimens does not enable the identification of the key characteristics in the apical horn, and in the upper segments. In disagreement to the description of S. carnegiense , the described species also bears spindle-shaped outline.
