SYSTEMATIC AND BIOLOGICAL ACCOUNT 119 Using again the terminology that I employed in 1932 (p. 318) the headpiece of the bract would be described as small, the phyllocyst comparatively small and near the apex. In optical section the head and neck shield resemble those of Diphyes bojani. The sutural surface is in a groove. In fact the whole bract has not evolved far beyond the developmental stage through which Diphyid eudoxid bracts pass. The edges of the sutural surface tend to lap over one another as if lapping round the stem. These ventral edges are cut away like the sides of a man's tail-coat till they meet the dorsal edge of the bract. The tip of the bract is rounded and conical, and the sutural surface does not reach the apex. The eudoxid, then, may be regarded as more primitive than that of a species such as D. Man.
