. Bulletin of the British Museum (Natural History), Geology. . Figs. 25—27. (25)Occlusal aspect. Dissopsalis pyroclasticus sp. nov. Right mandible with P4, Mi_3. (26) Lateral aspect. (27) Medial aspect. Holotype (), Kaboor. xi. Description. The mandible is robust and heavy. The symphysial junction extends back as far as the middle of P2. The canine alveolus is not fully preserved but suggests a normal sized canine. Px is single rooted and crowded behind the canine. P 2 and P 3 both had large double roots and were tightly packed against each other close behind Pr P4 is a large heavy tooth; the cusp is keeled anteriorly and posteriorly, the posterior keel continuing into a small accessory cusp, trenchant buccally and sloping down to a cingulum on the lingual side. Mx is smaller than P4; the trigonid is greatly worn, and of the three cusps the protoconid was larger than the paraconid, while the metaconid was very much smaller than either of the others; the talonid is broken, but must have been about the same length as the trigonid, basined with high buccal rim and low lingual rim. M 2 is larger than M1 but structur- ally similar; the metaconid is reduced to a minute peg and the paraconid-protoconid.
