“ Calymene” oldhami Reed, 1915

Figs 10.11, 12

1915 Calymene oldhami sp. nov. Reed; p. 47–48, pl. 8, figs 10,11.

Material. Holotype: cranidium with partial thorax and hypostome in part and counterpart from Lower Naungkangyi Beds (probable Darriwilian) at Man-shio, Figs 10.11, 12 (Reed, 1915, pl. 8 figs 11,10), GSI 11557, 11558.

Discussion. A single small cranidium was the basis for this species. Reed (1915) illustrated both part and counterpart of this specimen, and this is followed herein. However, the specimens have deteriorated since their original description. For example, the hypostome is quite clearly shown on Brock’s illustration (Reed, 1915, pl. 8, fig. 11) and displays the median fork consistent with calymenid affinities; this is no longer clearly shown. They are included here for completeness. It is not possible to give a more precise generic assignment to this species, which is best regarded as a nomen dubium.
