What ap- pears to be a slender separate ossification (uroneural?) dorsal to urostyle may actually be part of it. Bases of neural and hemal spines of vertebrae 1 and 2 indistinct. The caudal skeleton of Ellopostoma, so far as can be deter- mined, agrees in almost all respects with the caudal skeletons of both Cobitidae (undetermined cobitid; Botia macracanthus) and Kneriidae (Cromeria, Grasseichthys) described and figured by Monod (1968). The cobitids and kneriids lack uroneurals; it is possible that one is present in Ellopostoma. The cobitids have hypural 2 fused to the ural centrum, whereas it is evidently free in the kneriids; the condition of hypural 2 in Ellopostoma is undetermined. All agree in having a single epural and five hypurals, except Botia macracanthus, which has six hypurals. Rosen and Greenwood (1970: 13, fig. 10) found six hypurals and two epurals in Kneria wittei and in Parakneria sp. In K. wittei the first epural is very reduced, but in Parakneria sp. both epurals are Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
